A 12′ x 7.5′ to 13′ x 8.5′ trailer can be made with a single axle, but I wouldn’t recommend it because of the stability problems that can occur when pulling your boat through the waves at high speeds on a single axle trailer.

It’s best to have everything as rigid and sturdy as possible, so you get more helpful use from the trailer when you need it for hauling your boat around.

The best trailer for a 22-foot boat is a double-axle trailer measuring 13′ x 8′. This trailer will offer you much more stability than the smaller trailer options and will give you more options when accommodating your boat on the trailer. It’s best to keep your boat as low as possible for better stability while on the trailer.

The 13′ x 8′ double-axle trailer will sit low to the ground, so if you have an older boat with a high free board, it’s best to look at some taller trailers sized for 16 feet and up.

The higher profile of these boats may make loading and unloading in tight quarters easier due to the higher running board height.

A single-axle trailer will be more stable than a dual-axle one, but it’s not nearly as stable as a double-axle trailer. The benefit here is that you’ll save a lot on the weight of the axles.

A single-axle trailer can weigh considerably less than its two-axle counterpart, and by keeping multiples of axles, you can keep the weight down even more, when you want to take your boat somewhere specific.

Is A Boat Trailer the Same Length as The Boat?

A Boat trailer is a device towed by a truck, car, or SUV to transport watercraft. The vehicle towing the boat trailer is commonly called an auto carrier.

A boat trailer can range from a straightforward tow bar with axles and wheels to a full build-on trailer of various lengths and widths.

No! Boat trailers boast two feet longer than the boat they carry. There’s a good reason for that. When loading a boat on a trailer, there are many things to consider: Weight, balance, and center of gravity.

Longer trailers help distribute weight evenly and make the boat more stable. They also ease the process of turning sharp corners or backing onto ramps or docks because there is more room for error.

Because the boat is the heaviest item on the trailer, it will be located over the axle.  Without a ramp to load your boat, you would have to lift it onto the trailer and tilt it back.  

The longer your trailer, the easier that job becomes. Loading a boat can be physically demanding for even experienced boaters, but with a long enough trailer, you might not break a sweat as you find your rhythm.

Another reason to choose a boat trailer with a bit of length is the ease with which it can be pulled. If a boat has less freedom to move around on the trailer, it’s less likely to cause problems on the road.

Longer trailers make for more stable rides because their longer wheelbases help reduce “squatting”

–A phenomenon where boats sit lower in the water when hit with a wave or pothole and weigh down the front as they raise the back end.

Does A Trailer Measurement Include the Tongue?

No! A trailer measurement does not include the tongue. Boat trailers have to be partially disassembled to transport a boat.

These trailers are designed with a tongue and hitch so that the trailer can be towed by car or truck. The measurement of a trailer does not include the tongue.

The measurement for any trailer is from the hitch to the back of the tires, including tire size and the tongue.

If a boat is transported in a trailer and the waterline is lower than before, the boat will have to be re-positioned inside the trailer when it arrives at its destination.

The trailer measurement and waterline are not affected by transportation. A boat that is transported through water would also be affected by water exposure. The waterline measurement will have to be redone.

However, it’s possible that the boat has changed in length because of relative movement. This is not considered a transport problem and, therefore, would not require a new trip measurement.

Note that the trailer measurement only determines the distance from the hitch to the back of the tires. The tongue is part of the trailer and does not come into play.

If your boat is transported in a trailer, the trailer and waterline measurements will have to be redone when it arrives at its destination.

How Wide Is the Average Boat?

First, it depends on what type of boat we’re talking about; some boats have different shapes and sizes.

The key is to find the average width of a boat with a length of 7.5 meters (25 feet), which is the length of an average fishing boat.

From there, we will look at the range of space in total length and width, as it depends on the type:

Rudderless sailboats: Between 3.1-3.5 m (10-11 ft) wide, in total length only between 3.1-3.5 m (10-11 ft) wide, in total length only.

Sailboats: Between 3.5-8 m (11-26 ft) wide, in total length only between 3.5-8 m (11-26 ft) wide, in total length only.

Motorboats: Between 5-12 m (16-39 ft), in total length only.

Fishing Boats95 inches
Deck Boats18-to 26-feet
Dindhies Boat15 fee
Pontoon Boat12feet
Runabouts16 to 33 feet

How Wide is A Boat Trailer?

The total width of your trailer, including the side rails and tongue, is about 8.5 feet wide.

The side rails are 6 inches (1 foot) apart at each end; The trailer’s tongue is 4 inches (0.25 feet) wide from the inside edge to the inside edge.

It’s often helpful to include these dimensions in a “bow flange” with the measured length and width on a piece of paper or graph paper.

The side rails on your trailer come in at 6 inches on a 24-inch axle. The total width measurement, including the front and rear rails, is 8.5 feet.

The tires are 12 inches wide, but this won’t be the full width of your trailer.

On a 24-inch trailer axle, each tire sits on a 24-inch section of the frame that’s 6 inches deep to accommodate extra thickness in the frame and wheel travel area.

The 24-inch axle is the smallest allowed axle diameter, based on gross vehicle weight rating (GVWR), so it doesn’t matter if you have 16-, 20-, or 24-inch tires.

The wheel travel area is about 5.5 feet; by adding 2 inches for the angle at which the tires sit in their respective spaces, that’s 6.5 feet for a 24-inch trailer axle (1 foot for each side of the trailer).

For simplicity’s sake, the tongue, which we’ll call the main body of your trailer, is 4 inches (0.25 feet) wide from the inside edge to the inside edge. The trailer width, including the rails and tongue, is 8.5 feet.

How Is Trailer Tongue Length Measured?

Trailer tongue length is measured from the center of the tow ball to the center of the front frame of the trailer.

Trailer tongues are measured in inches, and it’s important to understand how they affect your towing capacity. You can tow heavier trailers with a long tongue or more weight with the same trailer.

If you need more tongue length, you may need a dolly or gooseneck hitch attachment to compensate for the lack.

This issue becomes more prevalent when steep grades are involved- because the increased slope will reduce your truck’s maximum load capacity.

You should always consult the owner’s manual of your tow vehicle and trailer because it will contain the proper tongue loads for all potential combinations that may be used.

The top row shows the various tongue lengths and what they’re best suited for in terms of trailer type.

The second-row shows which trailers you should avoid because they exceed the maximum weight limit for each tongue configuration. The third row shows which trailers you can tow, but weight limits apply.

The Trailer Weight Ratings (TWR) for many tongue configurations exceed the maximum allowed weight. This is because a certain amount of tongue weight is required to meet safety requirements.

The fourth row indicates the tongue configuration you should use, given that weight capacity is not exceeded. If you had to choose one specific tongue configuration for all possible trailer types, this would be the one.

Remember, tongue length is one of many critical factors. Many other factors go into the towing weight distribution. Pay attention to the chart and test your system to avoid problems down the road.

Boat Trailer Frame Material Options

AluminumAluminum is the lightest of all materials. It’s not rustproof but can be coated with paint or polyester resin to increase its corrosion resistance.

The lightweight nature of aluminum makes it one of the most expensive materials for boat trailers.

Aluminum conducts heat and cold very quickly, so it’s not a good material for long-term use on a boat trailer that will see high temperatures.

Such as those in colder climates or during summers where temperatures regularly surpass 80 degrees F (27 degrees C).
SteelSteel is the most common frame material for boat trailers and other forms of transportation, such as RVs. Steel is easy to weld, so repairs are not a problem.

Some steel frames have a galvanized coating to protect them from rust. Steel resists heat and cold well, although it is heavier than aluminum and fiberglass.
CompositeA composite frame is made of a combination of materials, usually wood, various metals, plastic, or polymers. Composite frames are lightweight and easy to repair in the event of damage.

They resist weathering well, so they can be used in warmer climates or extreme cold and heat. However, they are expensive when compared to other materials.

Because of their density and rigidity, there is risk of damage to your boat if you don’t properly secure it while transporting it on the trailer frame.
FiberglassFiberglass is the most expensive material for trailer frames. Unlike steel and aluminum, fiberglass resists temperature changes and does not conduct heat or cold.

However, fiberglass can crack when hit with a hard object or if the frame is hit with an extreme change in temperature.

Fiberglass is also difficult to repair if it becomes damaged from an impact of a hard object or sharp objects, such as rocks or shells.
WoodWood is generally expensive and tends to be heavy. It can also warp, increasing the risk of your boat rubbing against the trailer frame and damaging it.

However, wood is easy to repair and a good option if you use your boat trailer only in warmer climates like those found along the coast.

How Much Does A Boat Trailer Weigh?

Heavier boat trailers can weigh up to 3,000 pounds. You need to weigh boat trailers before they are used for the first time and then once per year.

You may have to weigh the boat trailer more often if it’s loaded with heavy cargo or often used on rough roads.

Kayak  Trailers100 and 400 pounds
Jet Ski  trailers300pound
Motorcycle Trailer500 pounds
Fishing Boat600 pounds
Tow Dolly 800 pounds
Large Boat2,200 pounds

How Should a Boat Fit In The Trailer?

First, you need to check if the trailer is big enough. The trailer must have a few inches on each side of the boat. Your boat should have a gap of at least six inches from the end of the deck.

If unsure, you can use a measuring tape to measure beforehand: It typically has a 2-3 inch margin for error.

You must center your boat in the trailer so that when you drive away with it, there’s no risk for swaying and instability in the load on both sides.

Next, you should check if the mast is too high. If the boat is stacked on top of a vehicle, ensure that the mast height or sails don’t reach the vehicles’ roofs or tops.

Ideally, you also want to avoid projecting sails or parts of it outside the trailer (e.g., sail bag).

You can achieve this by lowering your boat’s centerboard and rudder, as well as its mast height and overall length (e.g., booms).

Additionally, check if your boat tends to sway to one side when loaded, and make sure the load is even and centered. You can also use weight bags on the opposite end normally used when trailering your boat.

Another important thing to check is the coupling system between your trailer and vehicle. Ensure it’s tight by checking that your boat doesn’t waggle up or down while driving.

It’s also important to have no gaps or cracks in the trailer (e.g., where the hitch connects).

Lastly, if you have a trailer tongue jack, make sure its operation is within limits (e.g., max height that it can operate to). These jacks shouldn’t be able to lift the trailer off the ground while your boat is still attached.

How Wide Should Be A Boat Slip?

Boat slips are 60 inches (1525 mm) wide, minimum. Suppose your slip isn’t wide enough for your preferred type of vessel.

In that case, you may need to find another location or talk with the facility manager about installing in-slip utilities before purchasing your slip.

The size of the boat slip directly impacts the cost and complexity of many utilities. As a boat slips width increases, the cost and requirements for electrical, water, sewer and telephone/cable TV (if offered) will increase.

Boat slip width is based on the type of vessel that will be moored in it. This is important because some types of vessels require more services than others.

Likewise, some vessels have equipment that uses more services than other vessels.

You must determine the type of vessel you own or plan to purchase and choose available boat slips based on the vessel’s width.

Using a boat slip that is too narrow for your power requirements could pose a fire hazard or cause equipment to overheat.

Choosing a slip too narrow for your vessel may also damage the boat, causing frustration during docking and undocking. Marina staff have difficulty servicing your boat due to inadequate space.

Do Boats Over 20 Feet Need A Capacity Plate?

No! According to Federal Law mandates, Title 46, Section 183.4 stipulates that boats between 20 and 26 feet long can have capacity plates that are not within reach or in plain view of the operator.

The law also allows boats with a length between 26 and 40 feet to have capacity plates obscured by deck hardware as long as they still follow all other labeling requirements for boats carrying passengers.

This last requirement is critical to small vessel operators, who often fit their boat with equipment that warrants a capacity plate, but then have the plate obscured by accessories like antennas and windlasses.

These accessories can obscure the plate if the boat is under 26 feet long and are not accessible to the operator while at sea.

However, nothing in the law limits what accessories can be used to obscure or obscure access to a capacity label.

This has led to a near-literal interpretation by some inspectors that the equipment must be hidden and out of reach from the occupant or directly accessible and able to be read from the seat of the boat before the capacity label can be obscured.


Boat trails are great training devices and a wise investment of time and money. Make sure you find someone that operates the trail well and has clear concise instructions.

Take time, double-check your boat for damage before onboarding, and enjoy the ride.


Hi! I' am Tom. I was a manager in one of the biggest stores for over 10 Years, am also an SEO by night. I don't like to call myself a blogger; they are very analytical, do email marketing, and know all SEO stuff. I faced many questions from customers about different products, and there was hardly any help on the internet. After learning all the things about these products as a manager the hard way, I decided to start a blog and help other people.
