Boat Trailer Weight Calculator
Boat Trailer Weight
Calculate the total tow weight of your boat, motor, trailer, and gear to determine if your tow vehicle can safely handle the load.
Formula
Total Tow Weight = Boat Weight + Engine + Trailer + (Fuel Gallons x 6.3) + Gear; Tongue Weight = Total Weight x 10%; Remaining Capacity = Tow Vehicle Capacity - Total Weight
Frequently Asked Questions
How do I calculate total boat tow weight?
Add the dry weight of the boat, engine weight, trailer weight, fuel weight (about 6.3 pounds per gallon of gasoline), and all gear and equipment on board.
What should tongue weight be for a boat trailer?
Tongue weight should be 7 to 11 percent of the total trailer weight for proper stability. Too little tongue weight causes trailer sway, while too much can overload the rear axle of the tow vehicle.
Can I tow my boat with an SUV?
It depends on the SUV towing capacity. Most mid-size SUVs can tow 3,500 to 5,000 pounds, while full-size SUVs and trucks can handle 7,000 to 13,000 pounds or more. Always check your vehicle manual.
