How to Measure a Boat Trailer

Mea­sure­ment is a crit­i­cal part of the boat trail­er pur­chas­ing process. Know­ing how to accu­rate­ly mea­sure your boat trail­er is essen­tial for ensur­ing the trail­er you pur­chase can safe­ly trans­port your boat. In this arti­cle, we’ll pro­vide an overview of the key mea­sure­ments you need to con­sid­er when mea­sur­ing a boat trail­er.

How to Measure a Boat Trailer

Mea­sur­ing a boat trail­er is rel­a­tive­ly straight­for­ward. Mea­sure the length of the trail­er from the tongue to the back. Mea­sure the width of the trail­er from one side to the oth­er. Mea­sure the height of the trail­er from the ground to the top of the frame. Make sure to mea­sure each dimen­sion twice to ensure accu­ra­cy. Once you have all three mea­sure­ments, you will know the exact size of the boat trail­er.

1. Over­all Length: Start by mea­sur­ing the total length of the trail­er from the very end of the trail­er tongue to the back end of the trail­er.

2. Bed Length: Next, mea­sure the length of the bed of the trail­er where the boat rests. This is typ­i­cal­ly done from the back end of the trail­er to the point where the bed meets the trail­er tongue.

3. Width: Mea­sure the width of the trail­er from out­side tire to out­side tire. This gives you an idea of the over­all width and can be cru­cial if you’re plan­ning to nav­i­gate nar­row spaces.

4. Height: To gauge the height, mea­sure from the ground to the high­est point on the trail­er when it’s lev­el. Be sure to include any­thing that sticks up, like guide posts or light bars.

5. Tongue Length: The tongue is the part of the trail­er that attach­es to your tow­ing vehi­cle. Mea­sure from the hitch to where it meets the bed of the trail­er.

6. Bow Stop Posi­tion: Mea­sure from the back end of the trail­er to the bow stop, which helps to keep your boat in place. This mea­sure­ment will help ensure your boat fits com­fort­ably on the trail­er.

You should also mea­sure the wheel­base of the boat trail­er. This is the dis­tance between the cen­ter of the front wheel and the cen­ter of the back wheel. Also its nice to know how to cen­ter a boat on a trail­er. Take the weight of the trail­er into con­sid­er­a­tion. You must make sure the trail­er you choose can han­dle the weight of the boat you intend to tow. Know­ing the weight of the trail­er and the weight of the boat you plan to tow is impor­tant to ensure safe­ty and prop­er per­for­mance.

How do you measure trailer length?

To mea­sure the length of a trail­er, you will need to mea­sure from the front of the trail­er to the back. Mea­sure the total length of the trail­er, includ­ing any over­hang or extend­ed parts. Make sure to mea­sure in a straight line and record the mea­sure­ments in feet.

If the trail­er has any addi­tion­al fea­tures such as a pop-out awning or bike rack, you will need to mea­sure those as well, and add the mea­sure­ments to your over­all length. You can also mea­sure the width of the trail­er, by mea­sur­ing the widest points from side to side. Make sure to mea­sure in a straight line and record the mea­sure­ments in feet.

Measure the Height of the Trailer

Once you’ve mea­sured the length of the trail­er, you’ll need to mea­sure the height. To do this, mea­sure the dis­tance from the ground to the top of the trailer’s frame. It’s impor­tant to remem­ber that the trailer’s tongue will add addi­tion­al height to the trail­er.

Measure the Width of the Trailer

The next step is to mea­sure the width of the trail­er. To do this, mea­sure the dis­tance from one side of the trail­er to the oth­er, not includ­ing the fend­ers. This mea­sure­ment should be tak­en from the out­side of the trailer’s frame. Read also our arti­cle about boat winch straps.

Measure the Tongue Length

The tongue length of a boat trail­er is an impor­tant mea­sure­ment to con­sid­er. This mea­sure­ment should be tak­en from the cen­ter of the trailer’s hitch to the end of the tongue. This mea­sure­ment is crit­i­cal, as it will deter­mine how far the trail­er will need to be from the vehi­cle when tow­ing.

Measure the Weight Capacity of the Trailer

To mea­sure the weight capac­i­ty of a trail­er, you will need to refer to the man­u­fac­tur­er’s spec­i­fi­ca­tions. This infor­ma­tion can be found in the trail­er’s own­er’s man­u­al or on the trail­er itself. It is impor­tant to take into con­sid­er­a­tion the size and type of trail­er, as well as any addi­tion­al load-bear­ing com­po­nents, such as axles, when deter­min­ing the weight capac­i­ty. You should also con­sid­er the weight of the trail­er itself, the weight of the load, and the weight of any pas­sen­gers or car­go that may be rid­ing in the trail­er. Con­sult­ing with a qual­i­fied pro­fes­sion­al, such as a cer­ti­fied mechan­ic, can help ensure that you are accu­rate­ly mea­sur­ing the weight capac­i­ty of your trail­er.

It is also impor­tant to ver­i­fy that the trail­er is prop­er­ly rat­ed for the weight capac­i­ty that you need. The trail­er should also be checked for any dam­age or wear that may affect its per­for­mance. You should check to make sure that the trail­er has been prop­er­ly main­tained, includ­ing any nec­es­sary repairs or replace­ments. Reg­u­lar main­te­nance will help ensure that your trail­er is able to han­dle the weight capac­i­ty that you need and that it remains safe to use.

Measure the Gross Vehicle Weight Rating (GVWR)

The Gross Vehi­cle Weight Rat­ing (GVWR) of a boat trail­er is an impor­tant mea­sure­ment to con­sid­er. This mea­sure­ment tells you the max­i­mum amount of weight the trail­er can safe­ly car­ry, includ­ing the weight of the trail­er itself. This mea­sure­ment can usu­al­ly be found in the trailer’s owner’s man­u­al or on the trailer’s frame.

Measure the Axle Weight Rating

Anoth­er impor­tant mea­sure­ment to con­sid­er is the axle weight rat­ing of the trail­er. This mea­sure­ment tells you the max­i­mum amount of weight each axle of the trail­er can safe­ly car­ry. This mea­sure­ment can usu­al­ly be found in the trailer’s owner’s man­u­al or on the trailer’s frame.

Measure the Load Capacity

The load capac­i­ty of a boat trail­er is anoth­er impor­tant mea­sure­ment to con­sid­er. This mea­sure­ment tells you the max­i­mum amount of weight the trail­er can car­ry, includ­ing the weight of the boat, trail­er, and any addi­tion­al car­go. This mea­sure­ment can usu­al­ly be found in the trailer’s owner’s man­u­al or on the trailer’s frame.

Checking the Trailer’s Tires

Once you’ve mea­sured the boat trail­er, it’s impor­tant to check the trailer’s tires. Make sure the tires are in good con­di­tion and inflat­ed to the manufacturer’s rec­om­mend­ed pres­sure. You should also check the tire treads, as tires with insuf­fi­cient tread will need to be replaced.

Checking the Trailer’s Lights

When mea­sur­ing a boat trail­er, it’s also impor­tant to check the trailer’s lights. Make sure all the lights are in work­ing order and that the wiring is in good con­di­tion. This is espe­cial­ly impor­tant if you’re plan­ning on tow­ing the trail­er at night.

Checking the Trailer’s Coupler

Anoth­er impor­tant step when mea­sur­ing a boat trail­er is to check the trailer’s cou­pler. Make sure the cou­pler is in good con­di­tion and secure­ly attached to the trailer’s frame. You should also check the cou­pler for any signs of wear or dam­age.

Checking the Trailer’s Frame

Final­ly, it’s impor­tant to check the trailer’s frame for any signs of wear or dam­age. Be sure to look for any rust, cracks, or bends in the frame. If you notice any signs of dam­age, the trail­er should be inspect­ed by a pro­fes­sion­al before tow­ing.

Conclusion

Mea­sur­ing a boat trail­er is an impor­tant step in the boat trail­er pur­chas­ing process. Know­ing the key mea­sure­ments of a boat trail­er is essen­tial for ensur­ing the trail­er you pur­chase can safe­ly trans­port your boat. In this arti­cle, we’ve pro­vid­ed an overview of the key mea­sure­ments you need to con­sid­er when mea­sur­ing a boat trail­er, includ­ing the length, height, width, tongue length, weight capac­i­ty, GVWR, axle weight rat­ing, and load capac­i­ty.
