Bunk Vs Roller Trailer-How They Differ In 2022

There are two main types of boat trailers on the market, Bunk Vs Roller Trailer

The main difference between Boat Trailer Roller and Bunk are their structure. Boat Trailer Roller has a series of rollers that support the hull of the boat, while Bunk has a series of cross beams that the boat rests on.

Rollers are typically better for boats that have a smooth hull, as the rollers will provide support and minimize friction. Bunks are typically better for boats with a rougher hull, as the bunk will provide more support and grip.
Another difference between the two types of trailers is how they load onto the trailer. Rollers typically load from the front or rear of the trailer, while bunks typically load from the side.
Finally, rollers are typically less expensive than bunks. This is because they’re simpler in design and construction. Bunks are typically more expensive, but they offer more support and stability for your boat.
This can be a significant difference between roller boat trailer vs bunk, especially if you’re loading your boat by yourself. If you have a larger boat, or one that’s difficult to load, bunks may be the better option.

When choosing between a boat trailer roller bunks,  it’s important to consider your boat,

Your budget, and how you’ll be loading your roller boat trailers.

With this information in mind, you can make the best decision for your needs.

What Is A Bunk Trailer?

There are generally fishermen who buy bunk trailers as they offer an elegant solution.

In other words, there is less space between the axles, making maintenance easier compared with a roller-trailer.

What Is A Bunk Trailer

The price of Bunker Trailers can be lower than Rolling Trailers.

In this way, they appeal to fishermen with limited budgets. Bunk trailers can be useful for regaining your vehicle. You’re only necessary to put the boat into its container.

Bunk barges are generally less expensive than rollers.


Advantage of Bunk Trailers

Roller trailers are that they can be used in narrower waterways (since the boat rests on the bunks rather than the rollers) and are less likely to damage the boat if it is dropped onto the trailer.
The advantage of bunk trailers is that they can support a large boat weight capacity.
Many boat trailer manufacturers use this type of trailer rollers for their products because of the high load capacity and durability.
Bunk trailers are also more common than roller trailers in most areas since many companies have been using them for years to deliver boats, RVs, and other large items.
This means that you may have an easier time finding a bunk trailer to rent or buy than a roller trailer.

Disadvantage Of Bunk Trailers

The main disadvantage of bunk trailers is that they are more difficult to launch and recover, particularly with high freeboard boats,
As the boat needs to be lowered down onto the bunks. Bunk trailers with integral launching ramps, such as the ‘Stingray’ trailer, are available which overcome this problem.
The boat designs where the propeller is housed in a skeg or similar structure behind the rudder can be difficult to recover with a bunk.
The main disadvantage of boating on bunks is that if it is necessary to transport the boat on a steeply graded vehicle hoist, the boat will need to be supported by slings under the hull. This can damage the bottom of boats with integral bottoms, particularly fiberglass hulls.

Trailer Keel Pads For Bunk Boat

These are placed under the keel beam to help protect it from damage. They also provide a buffer between the boat and the trailer, which can make loading and unloading easier.

Just like with keel rollers, there are many different types of keel pads available. You’ll need to select ones that are compatible with the width of your beam and the diameter of your rollers.

It’s also important to choose keel pads that are made from durable materials. This will help to ensure that they last for many years, even with heavy use.

Once you have the right keel pads in place, you can be confident that your trailer is well-protected. This will give you peace of mind when transporting your boat, knowing that it is safe from harm.

What Is Roller Trailer?

Bunk Vs Roller Trailer

Roller Trailer is widely recognized for its modern style.

They are easier to manage compared to trailers because there is easy access even to salt water.

The roller makes towing simpler when it is backed by a trailer winch.

Because there are moving parts the motor needs frequent maintenance like removing the wheels of the machine for the repair and maintaining them in a clean condition for good health.


Advantages Of A Roller Trailer

The roller trailer is that they are easier to launch and recover as the boat sits on top of the rollers rather than being lowered down onto bunks.
This is particularly important for boats with a high freeboard (the distance from the waterline to the deck) such as speedboats and cabin cruisers.
Rollers also make it easier to move the boat sideways for a “two-point turn” maneuver when turning around in a narrow space.

Disadvantage Of A Roller Trailer

The main disadvantage of a roller trailer is that it can be more dangerous than bunk trailers,
Since the boat may slide off the rollers while being transported on a road, especially if brakes are not applied correctly or at all.
Roller trailers are more likely to suffer damage if the boat is dropped on the trailer during launching or retrieval since concrete bunks act as shock absorbers, dampening some of the impacts.

Trailer Keel Rollers

These are the supporting beams that run along the bottom of the trailer and provide stability during travel. The rollers help to keep the boat level and supported, making it easier to load and unload.

There are many types of keel rollers available on the market, each designed for a specific type of boat. It is important to choose the right ones for your vessel to ensure safe and easy transport.

Some of the things you’ll need to consider when selecting keel rollers are the width of the beam, the diameter of the roller, and the material it is made from.

You’ll also want to make sure that the rollers are spaced evenly along the length of the trailer.

Once you have the right keel rollers installed, you’ll be able to load and unload your boat with ease.

This will make it easier to enjoy your time on the water, knowing that your vessel is safe and secure.
