Importance of Tongue Weight When Towing Your Boat


Why is tongue weight important when towing a boat? Since it’s mentioned in the introduction that little tongue weight is dangerous, it’s normal to think about what it does.

What is a tongue weight? It’s a unit used for the amount of force delivered by the trailer’s tongue. This force goes down onto the hitch on the vehicle used for towing.

Therefore, the tongue’s weight affects how the force lands on the hitch. When there’s little weight, the load tends to move forward to the trailer’s axle. Excessive weight is not good as well as it can guide the cargo weight to be more contained behind the trailer’s axle.

1. The Right Tongue Weight

You can obtain the right tongue weight through calculation. The digit that you need to find is called ‘gross trailer weight’. You have to do the math as the manufacturer can’t provide it.

There’s no exact formula as all you need to do is get the trailer weight after you loaded all the stuff when boating. Hence, the weight of the items that you take with you adds up to the boat trailer tongue weight.

The right tongue weight is around 9% to 15% of your trailer’s total weight. Some experts may say that 6% is advisable for a single axle trailer and 5% is just right for a double-axle model. But when it comes to a trailer and other larger units, the higher percentage, the better.

2. The Usual Steps to Check the Tongue Weight


As mentioned, the right tongue weight for a trailer is 9% to 15% of its weight. To confirm the percentage, you have to check the gross trailer weight.

  • Step 1: The first step is taking your trailer to a scale that has enough space. You can rent a scale in your local area for a few dollars.
  • Step 2: Detach the trailer from the towing vehicle. Before checking the weight of your trailer, make sure that the towing vehicle won’t get in the way. Place it far away so it doesn’t touch the scale.
  • Step 3: The entire trailer should be on the scale, including its tongue, trailer wheels, and other trailer accessories. It should be done for the precision of the weight. When the tongue is out of the scale, you’ll get a number that is lower than the ideal tongue weight.

You may choose to weigh your trailer with all the stuff that you take when sailing. It’s applicable if you weigh the empty trailer then add the weight of the load. Knowing just the trailer’s weight is convenient as there are various load weights whenever you go boating.
