Ship pipelines can transport many things including water, oil, air, and steam. More often than not, these pipelines pass through an array of different types of valves depending on pipeline pressure and overall usage and necessity. Below you will find description of the 10 different types of marine industrial valves that have well deserved their sea legs.


Gates are typically used in the wider sections of pipes to control the flow of heavy and solid liquids. They are specifically designed to control the opening and closing of liquid flow and are usually operated in a fully open or fully closed position with minimal obstruction through the bore/body.


Globes have a twisted bore that gives it the superior ability to regulate the flow of fluid beyond starting and stopping. It is often used for in-line applications and contains a disk blocker attached to the stem that can be lifted and lowered through the passageway and into the seat.


Check valves allow fluid to flow in one direction and open automatically when there’s pressure coming from the inlet side and close with outlet side pressure.


A butterfly has the ability to adjust and regulate the flow of liquids through different disc rotations on a notch positioning plate. They can be used on fresh water, salt water, lube oil and fuel oil systems.


Strainer valves separate liquid from solids, allowing fluid to flow in an application.


An excellent choice for shutoff applications, the ball valve controls fluids through application pipes using a spherical disc blocker.

Fire Hose

Fire Hose valves control the flow of fluid through various types of fire hoses for fire protection using a disc that lifts and lowers. This valve works in conjunction with Stortz, Nakajima, ANSI PIN and Morris type hose couplings.


Angle valves have outlet openings that are oriented at right angles to inlet openings that regulate the flow of fluid into the pipeline in an application. This valve utilizes a piston seat within the metal casing for control of the flow of fluid OR gas.


A storm valves main function is to take waste away from the main sewer line to avoid overloading of water and sewage. This valve opens and closes in correlation to flow that returns back to a seat.

Vent head

Vent head valves control air inside pipes that transport fluids moved by pressure from pumps. It reduces flow, turbulence and damage from shaking pipes by allowing excess air out of the pipe while containing fluid.

The complex nature of sophisticated marine electronics means you will likely run into confusion whether you’re a seasoned boater or a young novice. Before figuring out what you should have on your boat, it’s important to know the items available to you. The seven basic electronics all boats need are an AIS, chartplotter, EPIRB and PLB units, fishfinder, MFD, radar, and VHF radio.

            The AIS, or Automatic Identification System, consists of a transmitter and receiver used to provide a means of identifying and gathering information on surrounding boats and commercial ships. The data supplied by AIS units includes ship name, size, destination, and speed. The chartplotter is a convenient tool that allows its user to display digital charts and navigation on an LCD screen. It presents users with a real-time display of their location, and can provide routes and supplemental information such as speed and estimated arrival time.

            EPIRB (electronic position indicating radio beacon) and PLB (personal locator beacon) units are both important tools in case of emergency. Their primary function is to broadcast SOS messages to satellites to alert search and rescue authorities of the user’s location and need for help. EPIRB units are used when boats need assistance, and PLB units are for people in danger. Depending on the model, these units are activated manually or hydrostatically (by exposure to water).

            Fishfinders are sonar tools that give users a real-time look at the fish under, around, and in front of their boat. Fishfinders are commonly integrated into the chartplotter or appear in a system on your boat’s multifunction display. The multifunction display, or MFD, is simply the screen your electronic systems can be viewed and managed on.

            Radar gives users the ability to see things not visible to the naked eye. A radar sends pulses throughout the surrounding area which are reflected back by other boats, land, and even extremely choppy waters. Recreational radar units are capable of mapping distances ranging from 20-70+ miles away. The final component, VHF radio, is the most important communication tool onboard. It enables the user to communicate with other boats and the coast guard from 20 or more miles away.

Most boats rely on an outboard engine connected to a propeller to provide propulsion for the vessel. Alternate designs do exist, however, with one of the most popular being the waterjet propulsion.

Waterjet systems feature an intake, usually located on the bottom of the hull, which guides water into a pump powered by an engine. The rotating part of the pump is referred to as an impeller. Unlike a propeller placed freely in the water, and impeller is enclosed in the pump chamber. Water rotating inside the pump needs to be aligned before leaving the pump system, which is accomplished by a stator with guide vanes designed to direct the water beam in the correct direction. The water beam passes through an outlet nozzle at the stern of the boat, and the difference between the water flow at the inlet versus that of the water at the outlet creates a reaction force, or thrust, which pushes the boat forward.

There are two main types of pumps used in waterjet propulsion systems: axial flow pumps, and mixed flow pumps. An axial flow pump increases pressure by diffusing the flow as it passes through the impeller blades and stator vanes. The pump nozzle then converts the pressure energy into velocity, which produces thrust. Axial-flow pumps produce large flows at lower velocity, making it ideal for low to medium speed boats. Mixed flow pumps, on the other hand, incorporate aspects of both axial flow and centrifugal flow pumps. As a centrifugal flow pump creates water pressure by using radial flow, the pressure from mixed flow pump is developed by both diffusion and radial outflow. This ends up producing lower flows of water at higher velocity, making them ideal for high-speed boats.

Waterjets are suitable for both small recreational craft like jet skis and larger boats. A major advantage of waterjets is that nothing is protruding beneath the bottom of the boat, meaning less hydrodynamic resistance and safer operations in shallow waters. This is particularly useful for military and ambulance boats that must be functional in all situations and marine environments. Waterjets also do not create many vibrations, making it comfortable for passengers.

One of the challenges with waterjets is keeping a straight course. Waterjet boats do not have propellers or rudders, which are typically used to keep course, so other design measures must be used. A boat powered by waterjets is sensitive to load and has poor efficiency at low speeds as well, which needs to be taken into consideration.

Ships, submarines and other marine vessels are able to propel themselves using propulsion forces. There are a wide variety of marine propulsion systems that are available for private, military and commercial use. Below you can see a basic outline of the systems that are popular in the market.

Water-Jet Propulsion

Water-jet propulsion has been in use since 1954. Though it has undergone some advancements in technology,  the concept remains the same. Because it uses the flow of water to propel itself forward, this mechanism offers high-speed velocity for vessels while also causing less pollution to the environment.  The most important advantage of water-jet propulsion is that it does not cause noise pollution and offers high speed to the vessels. However, the water-jet propulsion as a ship propulsion system is costly to maintain compared to other propeller systems.

Nuclear Propulsion

Nuclear propulsion systems are mainly utilized by naval vessels. Nuclear propulsion, while very powerful, is a very complicated system that consists of water reactors and nuclear fission to fuel the vessel. In addition to propelling the vessel, the nuclear reactors in the ships are used to generate electricity.

Fuel Cell Propulsion

Some vessels utilize the fuel cell propulsion systems, which use hydrogen as the main fuel component. The way this works is that electricity is created in the fuel cell without any combustion whatsoever. The process is clean and therefore has been regarded as a very important alternative marine propulsion system. There are several types of propulsion under the fuel cell propulsion head like PEM (Photon-Exchange-Membrane) and the molten-carbonate system. For more information on marine propulsion systems, consult experts at Purchasing 3Sixty, the online distributor of hard to find marine and aviation parts.

If you’ve never purchased a pontoon before, or are looking to add another to your collection, it’s wise to know what to look out for. Not every pontoon is the same which is why it’s important to select the ideal pontoon for you. Novices, for example, might not do well with purchasing a vessel with advanced features, while seasoned pontoon riders will likely appreciate something that will give them more features to play with. Whatever the case, these tips may help you narrow down your search.

Speed and Stability

You should first consider what you will be using your pontoon for because there are different pontoons suited for different purposes, from cruising to skiing and waterboarding. Depending on your answer, you’ll want to choose the pontoon with the best speed and stability suited for your purposes. For example, if you know you’ll want to ride at high speeds, then you might be looking to buy a tritoon, which has three cylindrical tubes as opposed to just two, and can reach higher speeds than the pontoon.

However, if you’re simply looking for something with more stability, then you would definitely be more comfortable with a pontoon, which have been designed to be a safe floating platform, with less roll probability than skiing boats. Additionally, pontoons are also much easier to embark and disembark. While pontoons are designed for more stability, there are some tritoons in the market that have been specifically designed for advanced stability.

Cost and Accessories

The cost can also factor into your selection process. If you have a budget leaning on the lower end and you’re not looking to buy used, then you’re probably going to find more selections with smaller and starter pontoons than with tritoons. However, the benefit of buying more budget friendly is that you have more room to save up and buy accessories to enhance your pontoon. Buying a $45,000 pontoon or tritoon might not leave you with much room to purchase add-ons in the future. As the premier supplier of ship pontoons and floating decks, Purchasing 3sixty has a diverse inventory of marine parts for all of our clients’ needs.

A dock is obviously a necessary for boarding and departing from a boat. In some places, such as rivers, lakes, and reservoirs that don’t experience changing water levels, a fixed dock mounted on posts in the water serves as a stable and functioning platform. However, many bodies of water have changing tide levels, which a fixed dock cannot adjust to. Floating docks, meanwhile, can rise and fall with the tide, making it the logical choice.

To clear up any confusion, these are docks this blog is referring to, not wharves or piers. A wharf is used for large commercial shipping, while piers range in size from large enough to accommodate cruise ships, to small enough for a family motor boat. A wharf is solid and a breakwater point, while piers allow water to flow freely beneath them. In its singular form, “dock” refers to a small platform for a moderately sized boat, like a small pontoon or yacht. “Docks” plural is used to refer to a large network of slips, anchorages, etc.

As their name obviously implies, floating docks are different from fixed docks in that they float. They are not as stable as fixed docks, but can be repositioned and removed if needed, and can often be far more affordable than fixed options due to requiring a less rigorous design and installation. Plastic and aluminum are the favored materials for constructing floating docks, as they are lightweight, reasonably durable, and resistant to rotting, rusting, and corrosion. Floating docks can also feature resin tops for extra reinforcement and durability. Wood is also a commonly-used material, but requires lots of sanding, staining, and sealing to protect it from rotting. There are even inflatable docks that can be attached to larger boats and are typically used to launch smaller craft, such as jet skis. However, inflatable docks are not intended as a permanent docking solution, as they are not very durable.

Put simply, corrosion is a boat owner’s worst enemy. Sadly, for naval operators, corrosion is a natural process that occurs when  iron and oxygen react in water or react in moisture in the air. As a result of this occurrence, metal materials are weakened and deteriorate over time. Saltwater does not directly cause corrosion but speeds up the effects of corrosion on marine hardware parts. Saltwater is an electrolyte solution and contains more ions than fresh water, so the electrons can move more easily through the water, accelerating degradation.

There are various types of corrosion, each categorized in terms of the type of corrosive action a unit is exposed to. Though the name seems drastic, General Attack Corrosion is the most preferable type of degradation as it is the most predictable, and the easiest to treat. Localized corrosion such as pitting (the creation of small holes in the surface of a metal) can sneak up on you and become a difficult problem to fix.

To combat corrosion, protective coats act as a barrier against the damaging action of the water or air. Before applying any coat, the boat surface must be cleaned and clear of any remaining dirt or debris. Hydroblasting involves blasting the ship exterior using high pressure water jets. Any loose paint, salt, oil, or rust is successfully removed before the protective coat is applied. Abrasive blast cleaning is similar to hydroblasting; although, compressed air is sprayed rather than water. A differing preparation technique altogether would be the use of layers to remove any built-up dirt or oil. Whichever method you choose, the main objective is to prime the exterior of your boat for the protective coating. If the boat is not properly primed, the coating will most likely have a patchy application, perhaps leading to localized corrosion.

Working in a shipyard come with its own series of logistical problems. Temporary climate control systems help to combat any unwanted humidity or extreme temperatures that would adversely affect the preparation process. Though it may be tempting to skip this step when you’re in a clean, dry, shipyard, doing your due diligence at this stage will pay off later.

Knowing which metals corrode and the rate of corrosion is key to the proper maintenance of a boat. Pure iron corrodes quickly, whereas stainless steel, which combines iron and other alloys, has a slower corrosion rate. Galvanization involves applying a protective zinc coating to steel or iron to prevent any rusting caused by a reduction and oxidation of iron and oxygen in the presence of water and oxygen. Hot-dipped galvanization is a popular and effective method for exterior ship part coating.

The structures of a helicopter are designed to give it its unique flight characteristics, such as vertical takeoff and landing, and hovering in place. A helicopter flies because the rotors serve as rotating airfoils that provide lift, similar to how the wings of an airplane create lift. Air flows faster over the curved upper surface of the rotors, creating negative pressure, and thus lifting the aircraft. Changing the angle that the blades meet the wind increases or decreases lift, raising or lowering the helicopter. Tilting the rotor plane of rotation causes the helicopter to move horizontally.

The airframe of a helicopter is made from metal, wood composite materials, or a combination of the two. Usually, a composite component of many layers of fiber-impregnated resins are bonded together to form a smooth panel for the helicopter’s exterior. Tubular and sheet metal substructures are usually made of aluminum to provide the aircraft’s “skeleton,” but stainless steel and titanium are sometimes used in areas with higher stress or heat.

Like fixed-wing aircraft, helicopter fuselages and tail booms are truss-type or semi-monocoque structures of stress-skin design. Steel and aluminum tubing, formed aluminum, and aluminum skin are used to create the framework and the plating that goes over it to form the aircraft’s body. Firewalls and engine decks are typically made from stainless steel because of their higher fire resistance. Because of the multidirectional nature of helicopter flight, wide-range visibility is essential, and large windows made from polycarbonate, glass, or plexiglass are common.

Helicopter landing gear usually consists of tubular metal skids. Some do use landing gear with retractable wheels, however.

Helicopters use both reciprocating piston engines and turbine engines, with turbines being the most common. In both cases they work exactly as they do in fixed wing aircraft and connect to the transmission system. The transmission system transfers power from the engine to the main rotor, tail rotor, and other accessories during flight.

The main rotor is the rotating part of the helicopter that provides lift. The rotor consists of a hub rotor blades and mast. The mast is a cylindrical metal shaft that extends upwards from and is driven by the transmission. At the top of the mast there is attachment point for the rotor blades, called the hub. The blades are attached to the hub, and their rotation creates the lift and thrust that a helicopter needs to fly.

This rotation creates huge amounts of torque, however, which makes the helicopter want to spin uncontrollably. The most common solution is to add a tail rotor to the fuselage, a secondary rotary that is mounted vertically on the tail that spins in opposition of the main rotor’s torque. Other solutions exist however, like mounting two rotors that spin in opposite directions.

While the marine industry has long-since moved on from the days of wooden hulls and cloth sails, it’s always worthwhile to go back and revisit history every now and then. For this blog post we’ll look back and review the structure of an average sailing ship of the 1700’s—the kind that pirates would sail while charting a course across the Caribbean. 

All ships begin with their hull, the frame and body of the sailing vessel. The front of the ship is referred to as the bow, while the rear is called the aft. The stern is the foremost part of the ship, while the aftermost part of the ship is the stern, which typically was used as a captain’s office and officers’ quarters. The interior of the hull is divided by decks, horizontal platforms that cover the hull from one side of the ship to the other. In marine deck machinery, the top deck is also referred to as the main deck, while the lowest deck is the orlop, used to cover storage. Beneath the orlop is the bilge, where the bottom of the ship’s hull curves to meet along the keel. The keel stretches from bow to stern and could be compared to the spine in a human being, in that everything else is built off of it. Between decks, bulkheads add to the structural strength of the ship, as well as help prevent flooding from one compartment to another. Under the main decks are the berths, the living and sleeping quarters of the crew.

Above the main deck is the complicated system of rigging, which uses a network of ropes, wires, and chains to support and operate the masts, sails, booms, and yards of the ship. The masts are the tall vertical poles that stand vertically on the top deck of the ship and support the rigging. On a typical large sailing ship, there are three masts: foremast, mainmast, and mizzenmast, in order of bow to stern. Sails, the large pieces of cloth that hang from the masts and catch the wind to provide ship propulsion to the vessel, come in numerous shapes and sizes, each with a different purpose on the vessel. Square sails are best at capturing the wind but are also the most vulnerable to tearing in periods of high wind-speed. Therefore, in violent weather, they are replaced with trysails, which are smaller and triangular. Other triangular sails include the jib and lateen, which serve as the main sails in smaller vessels, and supplementary in larger ones. Sails hang from or are extended by a variety of poles called spars, such the yardarm, which hang horizontally from the masts.

The last major component of a ship is the rudder. Consisting of a large, flat wooden or metal control surface that hangs from the back of the ship and in the water, the rudder redirects waterflow as it passes the vessel, allowing it to turn left or right.

Marine hardware consists of all the woodworking, dock accessories, lighting brackets, oarlocks, and other components that boats are comprised of. This includes brass fittings and shackles, and rigging hardware made up of different types brass, steel, chrome, and even black nylon. Whether you’re working in the marine industry or own a boat yourself, your equipment can take a beating. This includes damage from corrosion enabled by salt water, or UV Rays that are strong enough to break chemical bonds.

The sun radiates energy in a range of wavelengths, most of which are invisible to the human eye. The shorter the wavelength is, the more energetic the radiation, which equates to more potential for harm. UV radiation has played important roles in our environment, affecting almost all living organisms. Humans are susceptible to sunburns and underlying sun damage created by these UV rays, and should take proper precautions; the same can be said for your marine equipment. Without proper care and maintenance, the sun can cause damage that may go unnoticed for some time.

UV radiation exposure can lead to damage on your surface equipment, and on your fastening equipment such as nuts and bolts. In addition, radiation exposure often enhances boat corrosion. UV stabilizers can aid in the prevention against UV radiation. Stabilizers can disseminate the rays into low heat across a surface area. It is crucial to select capable fasteners that can withstand high amounts of direct sunlight.

Marine fasteners can include screws, washers, nails, nuts, bolts, and rivets. There may be several different types of fasteners that are right for the function you intend it to have. Consider its purpose first, and aesthetics later. The general consensus is that stainless steel is the best all-around fastener material. Stainless steel offers superb corrosion resistance at an economically friendly price. All bolts, screws, washers and nuts should be marine stainless— one of the strongest and most corrosion-resistant marine metals. Avoid brass or aluminum for fittings underwater - they aren’t constructed with a suitable amount of corrosion resistance.

Most marine aluminum is made with a corrosion-resistant surface treatment; however, it is easily scratched. Salt can gain a foothold within a scratch that leads to pitting. Aluminum should be cleaned and polished to eliminate any opportunities for corrosion.

Protecting your marine equipment from UV rays and corrosion can prove to be beneficial in extending the longevity of your equipment.

In ship & marine equipment industry there are a few expectations that boat operators might have for their propulsion systems— low fuel consumption, high engine efficiency, high uptime, good performance, and easy operation. In addition to these consumer expectations, marine propulsion system designers also have to consider factors such as how it will affect the marine ecosystem and maintain cost efficiency during production.

Other considerations, such as the boats operating and load requirements, need to be considered as well. Because of all of the competing expectations and requirements, there is not a “one size fits all” kind of engine— there are many options to choose from: including diesel, wind, nuclear, gas turbine, fuel cell, solar, steam turbine, diesel-electric, and gas fuel or tri-fuel propulsion systems.

  • Diesel propulsion is the most commonly used engine system. They convert mechanical energy from thermal forces.
  • Wind propulsion has been considered because it doesn’t produce emissions that contaminate the environment. However, it is not the most practical choice— especially for large commercial ships— because what powers this system (wind) is constantly fluctuating.
  • Nuclear propulsion is a very complex system and is most commonly used on naval vessels.
  • Gas turbine propulsion produces faster movement and is used on both naval and non-naval vessels.
  • Fuel cell propulsion has been considered a clean process and is a potential alternative to other systems that use combustion to generate power— which produces exhaust.
  • Solar propulsion reduces carbon dioxide emissions.
  • Steam turbine propulsion was commonly used in the late nineteenth century and early twentieth century.
  • Diesel-electric propulsion are often used in submarines and merchant ships.
  • Gas fuel or tri fuel propulsion can burn gas, diesel, and heavy fuel.

                Determining what the most optimal engine will be depends on many factors which can vary in importance based on the operating and load requirements. Considering how much marine propulsion has evolved in the last couple centuries— we can look forward to seeing how efficient they will become in the future.

“Switches”, “transmitters”, & “transducers” are said interchangeably with no regards for the differences, but that’s wrong. They aren’t all the same thing. You can’t use a transmitter in place of a switch and expect your circuit to work the way you wanted it to. And one of the biggest reasons you would have used the wrong part is that you thought they were all the same and didn’t know the difference. In order to put an end to the confusion and misuse, let’s talk about the difference between pressure switches and pressure transmitters.

A pressure switch is an electromechanical device that measures a system’s pressure. When the pressure reading is too high or too low from a set point, the power switches to close or open a circuit powering a connected device such as an alarm clock or valve. Pressure switches get their name from that ability to open or close circuits— their “switching” ability.

A pressure transmitter, also known as a pressure transducer, is an electromechanical device that measures a system’s pressure and then sends a read-out signal of what the specific pressure value is to a remote location. Unlike pressure switches, reaching any level pressure does not lead to any overt change, only in a different value being sent to any device that requires that information.

Typically, pressure-system applications where safety is of the utmost importance will use a switch instead of a transmitter because a switch has an inherent safety-feature. High enough pressure readings can trigger the blowout preventer and “switch” the circuit open. But at the same time, a transmitter is significantly more versatile. With the help of 3rd party software, a transmitter can be used to measure the efficiency of pressure systems or control many industrial functions, like inlets, outlets, chemical or fuel mixtures, or even act as a safety switch itself. But that versatility does not come cheap— transmitters tend to be more expensive than switches since they are costlier to produce. In fact, extremely accurate and repeatable transmitters, not necessarily the best or most expensive already cost as much as over $1000 while the most expensive switches generally only cost half that at about $500.

Painting, cleaning, cargo handling, and operating deck machinery— there’s an entire laundry list of things to do aboard a cargo ship. And of course, when working with machinery, it’s important to make sure that all this work is done safely and properly but working at sea means that there are additional safety hazards. So, in order to save you from headache, you should remember to avoid these deck machinery system mistakes.

  • Ballast systems - Before using the ballast systems, remember to inspect the valves and area around the pump. You start the pump without visual contact of the system from the cargo control room, so it’s safer to know the conditions of all the affected areas before you start.
  • Bow thruster - Make sure that as you start the bow thruster, you increase the pitch slowly and you don’t let the maximum pitch exceed 90%; going from minimum to maximum immediately can damage the motor.
  • Deck crane - Be aware of the safe working load capacity of the crane system; it’s painted on the side of the crane body.
  • Fire systems - Maintain and inspect the pipes and all other mechanical components of the fire system prior to departure. You don’t want to deal with a fire only to realize your fire systems don’t work because of mechanical failure.
  • Hydro blaster - Before operating, know where the safety switch is. Also, don’t attempt to tape or tie the hydro blaster to keep it “on”.
  • Welding - Before attempting any weld job, make sure the check the surrounding area to make sure that things like the fuel tank vent, fuel containers, or wires are safe and secure. Heat damage can be irreparable.
  • Winches - Make sure to control the speed carefully and try to use the reduction gear instead of the brake. Overusing the brake tends to damage the drum lining.

And, as with all machinery, you need to remember that regular maintenance and repair is key to making sure that your deck machinery stays operating safely and properly.

Purchasing 3Sixty, owned and operated by ASAP Semiconductor, is a premier supplier of parts and components for the aerospace, aviation, and defense industries.

Often used in enclosed trailers or on the floor of an open trailer, e-tracks are track systems that accommodate fittings for tie-down straps with wide and flat profiles. They’re very versatile, so they can also be used in garages, storage sheds, barns, etc. But, before you decide to install an e-track, it’s important to first understand what kind of fasteners you should use.

Choosing the right fasteners to install your e-track is very important because otherwise your items could be incorrectly secured and become damaged as a result. There are three common types of fasteners for use on an e-track: through-bolting, self-drilling screws, and wood screws.

Through-bolting fasteners are bolts that go all the way through the item they are connecting and held in place with a nut at the other side, forming a “sandwich” connection. The use of a washer increases the holding power of the bolt, especially with wood surfaces. As wood shrinks and deforms from weather and environmental conditions, sometimes causing the previously tightly fastened screw to become loose and wobbly or even fall out. On the other hand, a through-bolt’s nut and washer can make tightening and readjustment a breeze.

Self-drilling screws are those that eliminate the need for pre-drilling holes. They have a drill-shaped point to cut directly through sheet metal and steel. They make it easier and faster to install the screws, increasing efficiency. Sometimes, creating a pilot hole with the wrong screw can leading to increased vulnerability and damage to the surface, which could make the e-track less secure. The use of a self-drilling screw can eliminate that.

Wood screws are specially designed to be driven into wood materials. They have shorter threading that does not run through the entire body and less pitches. Because e-tracks are commonly installed onto wooden surfaces, wood screws will offer a better and more secure hold as opposed to metal screws which can cause undue damage instead.

Going out into the open waters and feeling the ocean breeze in your hair, there are many things that make boating a fun experience. But, it can also be a slightly precarious experience; it’s easy to get lost at sea. While GPS is a godsend, it’s not infallible to dead batteries, lost signal, or jamming. You also need to be able to navigate the old-fashioned way, with buoys, beacons, lights, and charts.

When you’re out at sea, you’ll notice, as you look back to shore, that there are many different markers trying to convey different information. Beacons are the fixed structures like poles and lighthouses. Buoys are colorful floating structures, usually numbered and moored to the bottom. And then there are the lights on top of some of those buoys and beacons.

Most buoys will need the help of a chart in order to understand what they mean or refer to. There are two standard buoys, green cylindrical “cans” that are odd numbered and red triangular “nuns” that are even numbered. These are used to hint which way your vessel is headed. As your vessel leaves the marina, the first two buoys you’ll usually see are a green-can buoy on the left-port side labeled #1 and a red-nun buoy on your right-starboard side labeled #2. The numbers will increase as you head out farther to sea. Other buoys to keep an eye out for are red-green-striped buoys that indicate junctions, yellow buoys that mean caution, black and red buoys that indicate danger, and red-white-vertical-striped buoys that mean you’ve reached safe open waters.

Like buoys, you’ll need to reference your charts to understand them. There are (F1) flashing lights that have short regularly-timed flashes, (F1(2)) group flashes with two short flashes close together, (Oc) occulting with longer regularly-timed flashes, (ISO) isophase with flashes in increments equal to darkness, and (Q) quick with rapidly flashing lights to name a few.

Learning to navigate the coast with just buoys, beacons, lights, and a chart is not something that can be done overnight. It takes a while. But in the meantime, you can rely on us at Purchasing 3Sixty, owned and operated by ASAP Semiconductor, for all your marine equipment and GPS needs. We have everything from boat engines and navigational systems to buoys and beacons, both new and obsolete. Email us at to get started on a quote.

It’s a good rule of thumb to always be prepared. Having everything you could need can make all the difference. Especially on marine vessels meant for intensive work, like those used for offshore oil drilling or fishing, having the right specialty deck equipment can reduce operational time, improve efficiency, and save money. But, how? And what kind of deck equipment should you get?

As a specialized marine vessel, there are certain things that you’ll need based on the work requirements. Each and every project comes with its own unique challenges such as operational location, environmental conditions, sea depth, vessel weight and space restriction, load requirements, and safety factors. If you tailor your equipment to match those specific requirements, everything can easily work in tandem and flow more smoothly. And when things move smoothly, there are no unnecessary hiccups and delays, which means that everything can proceed on schedule. And that’s good because, delays can incur massive costs and losses.

When it comes to what kind of deck equipment you should get, it depends on what the vessel’s purpose is. For example, vessels that require winches, mechanical devices used to wind up and wind out ropes, might need additional equipment to improve the winch’s efficiency. A sheave, either horizontal or vertical, can be used to divert the path of a winch’s wire room so that the winch can perform functions like over-boarding. Swivel heads and roller box fairleads keep the wire rope firmly on the sheave, preventing damage to the sheave, rope, and winch. And snatch blocks can increase the load pulling capacity of a winch, allow for more work to be done more efficiently.

Of course, in addition to specialty deck equipment, it’s also a good idea to have things like spares, and repair and maintenance tools. At Purchasing 3Sixty, owned and operated by ASAP Semiconductor, we know how important it is for you have all the deck equipment you need. As a premier supplier of marine parts and components, we have everything from deck machinery to ship engines, and anything else in between, new or obsolete.
