How to Calculate Total Towing Weight Including the Trailer

When towing a boat, it is critical to calculate the combined weight of the boat and trailer to ensure the towing vehicle is rated for the load. The following steps provide a method to determine the total towing weight:

  1. Determine Boat Weight: Refer to the manufacturer’s specifications or use a certified scale to find the dry or loaded weight of the boat.
  2. Determine Trailer Weight: Check the trailer’s gross weight rating or use a scale to find the empty trailer weight.
  3. Include Additional Cargo: Add the weight of fuel, equipment, passengers, and any additional gear on the boat or trailer.
  4. Calculate Total Towing Weight: Add the boat weight, trailer weight, and additional cargo weight.

Example:

  • Boat weight: 2,500 lbs
  • Trailer weight: 1,200 lbs
  • Fuel and gear: 300 lbs
  • Total towing weight = 2,500 + 1,200 + 300 = 4,000 lbs

This total must be within the towing capacity of the vehicle, including the hitch rating.

Weight Considerations for Trailer Braking Systems

Trailer brakes are a safety requirement for many trailers over a certain weight threshold. The addition of braking systems impacts trailer weight and towing dynamics:

  • Electric Brakes: Typically add 50 to 150 lbs depending on the number of axles and brake size.
  • Hydraulic Brakes: Generally heavier than electric brakes, adding 100 to 250 lbs or more.
  • Brake Controllers and Wiring: Add minimal weight but are necessary components for brake activation.
  • Impact on Towing: Trailer brakes improve stopping power and control but require compatible towing vehicle equipment and proper maintenance.

When considering trailer weight, factor in the additional mass of braking systems to avoid underestimating total towing weight.
