Almost 72 percent of the Earth is covered in water, making it seem like a boater’s paradise where sailors and powerboaters alike can climb onboard their vessel and head for the open seas without a care.

Although there is a lot of water sloshing around on this planet, much of it is covering places too rocky, too shallow, or too dangerous which makes it extremely important that navigational aids show boaters where to go and what to avoid.

In every place, unseen obstructions and dangers exist below the water’s surface, making it important to understand the different types of buoys and markers that indicate where captains can find the underwater “roads and trails” that safely lead back home.

A wide variety of navigational aids, often referred to as buoys or channel markers, exists to protect boaters, property owners, and the environment, and help boaters find their way around.

Types of Channel Markers

Whether created by man or nature, the channels that provide deep water paths and help boaters get home with propellers intact must be clearly marked so vessel operators can tell where safe passage can be found.

Channel markers can be unlit triangular and square shapes perched on top of sticks, or well-lit red and green steel buoys anchored in place to keep captains from wandering into the rocks or mud.

The most important details boaters should learn about channel markers is how to understand what they are telling you.

  • Yes, the old adage “Red, Right, Return” is accurate, but only if you understand the meaning of the word “return.”
  • At the mouth of a harbor or port, the start of the channel will be clearly marked with a red and green buoy. If you are returning to port, the red buoy should be kept on your right, thus – RED on the RIGHT means you are RETURNING.
  • The opposite is true if you are headed out to sea. While leaving, keep the red on your left.
  • Once in the channel, there will be many places where only one marker is visible. Coming in from sea, a captain might pass a red marker on his right with no green on the left. Looking ahead, a green marker might be visible several hundred yards ahead.

By keeping the vessel between the markers and alternating red-right and green-left, the captain can stay in the channel and return safely to their home slip.

Navigation Lights

Whether found on a boat or on a marker or buoy, lights provide important navigation information to boaters returning to port in the dark.

Like channel markers, the red and green lights on top of buoys and larger markers tell captains how to find the channel and keep the vessel safely in deep water.

  • Like channel markers, red on the right means you are returning to your home port.
  • At the entrance to a channel, both red and green will be visible, while further up the channel, only one or the other may be present.

By paying close attention, keeping a single red on your right (while returning) means you should look for a green light next and keep it on your left—even if it is once again paired with a red.

Buoys and Other Boating Regulatory Markers

To protect other boaters, their property, and the environment, boating regulatory zones were created for different purposes. The boundaries around these zones are defined with white markers with orange shapes, such as a circle or diamond, and are used to inform boaters of no wake zones, exclusion zones, or speed limits.

  • A white marker with an orange circle is used to inform boaters of no wake zones, slow speed zones, or other important information.
  • White markers with an orange diamond shape are used to tell boaters of hazardous conditions such as submerged objects, rocks, and other dangers.
  • White markers with crossed diamond shapes are used to keep boaters out of dangerous spots such as that great fishing hole that’s a little too close to the dam or waterfall, or an area where boating would present a danger to others, such as in a swimming area.
  • Other navigation markers for boats provide important safety or directional info, such as red and white flags alerting others that divers are in the water.

It is important to learn how to properly read and understand navigational aids before hitting the water. Like street signs, markers and other navigational aids provide boaters with important safety and directional info to help get them safely home.

Why Should You Try Boating?

Before we go on and tell you more about the different boat parts and their uses and differences, give us the liberty to share the benefits of boating or sailing.

As some of you may already know, being out on the water has amazing benefits on one’s health—both physically and mentally. It is usually used as an escape from daily stress and pressure, and sometimes from the hustle and bustle of the city.

Boating, on one hand, gives a more calming effect than other water sports activities. In a book called “Blue Mind”, author and marine biologist Dr. Wallace J. Nichols stated that “the mere sight and sound of water promotes wellness by lowering cortisol, increasing serotonin, and inducing relaxation”. He also wrote that being on a boat is one of the easiest ways to harness the health and wellness benefits of the water.   

In addition, the marine biologist also noted that being around, in, or on the water shows positive emotional, behavioral, and psychological effects on a person. With more and more Australians getting busier with work and school, resetting our minds and bodies is a must.

Other than these, here are a few more advantages of boating that you might not have known!

Boating helps decrease risk from chronic diseases. People with chronic diseases like diabetes, asthma, and the like, would definitely need to make necessary lifestyle changes to keep themselves healthy. Water activities such as boating can decrease stress levels and keep them relaxed. This is good for their body, and their overall health.

It promotes bone and joint health. Our body can produce Vitamin D with the help of exposure to the sun, and this is important to keep one’s bones and joints healthy. Being out in the water on a boat gives you access to the sun, without facades like buildings blocking its light.  However, you would need to make sure to bask under the sun early in the morning when its rays aren’t that harsh. Applying a good amount of sunscreen wouldn’t hurt as well!

In addition, dangling your feet on the water can help soothe any aching joint as you enjoy its flow!

Boating is meditative and resets our brain. In a fast-paced modern world, people would sometimes need to pause and take a break. Being surrounded by the calm and serene water is a proven way to restore one’s mind. It has also shown to offer mediation, restoration of happiness, with the added benefit of exercise, social interaction, and reconnection with nature.

It helps with mental wellness. In connection to having a “blue mind”, being surrounded by water while inhaling the fresh, salty air can help improve one’s mental state. The salt in the air will help your body absorb more oxygen, which in turn helps balance your serotonin levels. In addition, the calming sounds of water flowing and waves crashing on the shore can put your mind in a relaxed state, thus regulating your mood. When your mind is calm, your body is also calm, and you feel refreshed to start things from a new perspective.

Boating is a good way to spend tome with family and friends. Let’s face it—it gets harder to spend quality time with our loved ones these days. With computer and screens dominating every aspect of our lives, it is important to reconnect with friends and family through physical activities like boating. You can explore and have fun, enjoy your time as a team, take turns in operating the boat, as you build and strengthen your bond with each other.

The Different Boat Parts and their Uses

Now that we’ve shared a few reasons why you should (definitely) try boating, let’s now move on to your boat’s anatomy. You might be familiar with some like the anchor or the bow, but what about the other boat parts and accessories? That’s what we will share with you in this part!

Boat Anchors – A boat’s anchor is what reins and secures it properly to the seabed so that it counterbalances wind and waves. Without the proper anchor, your boat might be carried away by strong currents and winds, causing harm to your boat, or to others’.

It is essential to first determine your boat’s size and weight before getting an anchor. Moreover, knowing the bottom conditions of where you will be sailing is a must. To know more about anchors and its different kinds, you can check out our product guide here.  

Boat Biminis – A boat bimini is a canvas that’s attached on top of a boat to provide protection from sun and rain. It is supported by a frame, and is usually attached to the cockpit. The name “bimini” is derived from the islang Bimini in the Bahamian Islands, where they were first created.

Some boat biminis can be collapsed when not in use, then raised again when needed. A bimini is most helpful to shield boaters from exposure to the sun, but cannot offer the same protection from the spray of rain or wind when the boat is in motion. This top accessory can provide protection from the rain only when it’s stationary, and wind isn’t present.

Marine Electric Parts – Marine electricity is a very important part in a boat’s operation. It is one of the most prominent boat parts, because without it, your boat wouldn’t be able to run any of its machinery. You wouldn’t be able to sail anywhere you want that way, right?

Marine Electric Parts include (but are not limited to) marine switches, anchor winch wiring looms, and tinned copper marine lugs to safely connect any cables or power lines in your boat.

Marine Anchor Winches - A marine anchor winch is a marine winch that contains a series of flexible metal rings or links fitted into each other. Its main purpose is to draw and anchor and its line. The size and power of a boat’s anchor winch will depend on the anchor and line it will pull. A marine anchor winch can be horizontal or vertical.

They can be powered by electricity or hydraulics, but there are also manual winches that are used by hobby boaters. These winches are used bot only for drawing anchors, but also for lifting boats into a trailer.     

Boat Mooring – When one moors his boat, it means that he’s securing his boat to a fixed object rather than dropping an anchor. Boats can be moored to a mooring buoy, dock, pier, or a wharf. Other than these, you can also use a mooring whip to tether your boat.

Mooring whips are like giant fishing poles that are mounted on a dock. These mooring accessories are used to secure boats from hitting the docks, making mooring easier and safer.

Marine Windchargers – Also known as wind turbines or wind generators, marine windchargers are alternative ways to generate power in your boat. This happens when wind turns the propeller-like blades of the turbine and spins a generator, which in turn creates electricity to power your boat.

Marine windchargers can be used alone or as part of a hybrid system that can be combined with solar panels and/or an onboard generator. One of the best marine windchargers in the market these days is the Rutland i 24V wind generator which can generate 1,6amps in 10 knots of wind.

Fish Finders – A fish finder is a device that utilizes sonar technology to locate fish and other objects underwater. Nowadays, fish finding software can be purchased from boat parts online stores, and can turn your PC or laptop into a full-color fish finder.

Fish finders like the CruzerPro PcFF80 can run under analog or DSP (Digital Single Processing) mode, and are compatible with different Windows versions—from Windows98 to Windows10.

Boat Hydrofoil Outboard Stabilisers – You might have read about hydrofoil boards from our previous blog post, but this time, hydrofoils are utilized in a different way. As mentioned before, hydrofoils are wing-like structures that lift a board, in this case a boat, out of the water.

When attached to a boat, a hydrofoil stabiliser reduces the overall drag and increase speed when the watercraft is moving through water. It redirects the water flow downward, reducing resistance and helping a boat travel faster. When a boat is more stable, it promotes safer and smoother sailing that everyone on board can enjoy.

Seems like a lot to learn about, right? AS we have said in the first part of this explainer, experience is the best teacher when it comes to boating. With a curious mind that tends to read and research, and an adventurous spirit that’s always on the go, we’re sure that you’ll be a boating pro in no time!
