The height of a boat on a trailer would depend on how tall the boat and trailer are from the start.

A typical trailer is usually about 2ft high which means you have to add that to the initial height of your boat to get the final height measurement.

So an 18x20 feet boat will usually be above 8ft tall on a trailer although with some exceptions.

Like, if the boat has a hardtop or a radar it will lead to an added height of 1 or 2 feet increase it to 10ft or more.

Overall a boat on a trailer is 2-2.5 feet taller than the original height, only within travel lanes also known as "bridge clearance" this is usually listed on your manufacturer’s specifications.

Here is a tabulated list of some of the different types of boats and their heights on a trailer:

Boats Height On A Trailer
22 feet Robalo 9-10 feet (12-13 feet with a hardtop)
22’ Grady 12 feet even with a hardtop
Hewescraft 22’ 9 feet even with a top
20’ center console 10 feet
24’ Robalo 11½ feet
28’ Wellcraft 12½ feet
23’ Hydrasport Vector 11½ feet even with a top

How to choose a trailer for your boat

A trailer is an essential means to move a boat to new places without having to rent a ridiculously expensive slip.

A good trailer is supposed to fit your boat to the T, it should be the right size.

As a rule of thumb, trailers with a single axle are for smaller boats (22-23 ft) plus they cost less.

Bigger boats can fit on trailers with two or more axles, they will cost more obviously.

Also, the type of material that your potential trailer is made of is important as a galvanized trailer is heavier than the rest.

Additionally, brakes mechanism are important in choosing a trailer as it is in a car. A trailer with an electric brake is not the best option because when they come in contact with salt water, its electric potential can increase dramatically and it is not a good idea.

The best type of brakes a trailer should have are the surge types of brakes, although they are more complex they don't have potential risks as opposed to electric brakes.

In summary, choosing the right trailer for your boat isn't supposed to be hard, just remember to put the following into consideration beforehand:

  • The size of your boat,
  • how heavy the front of the trailer is (tongue weight,
  • number of axles,
  • it's support system: rollers or bunks,
  • how easily their clamps connect to tow vehicles,
  • type of brake on the trailer: surge or electric,
  • the material makeup of the trailer: galvanized, steel, or aluminum.

Although they are more factors, these are the most important ones to consider before choosing a trailer for your boat.
