If you don’t have enough weight on the trailer tongue, the trailer may be prone to swaying from side to side, making it difficult to control. Conversely, if you have too much weight exerted on the hitch ball, the force could overload the rear tires of the tow vehicle and push the rear end of the vehicle around.
Tongue weight should be between 10-15 percent of gross trailer weight (GTW). For example, a 10,000-lb trailer should have a tongue weight between 1,000 lbs and 1,500 lbs. You can adjust the tongue weight of your trailer by removing or adding cargo, or redistributing the load on the trailer.
To determine proper tongue weight, total the package weight ( boat with fuel/battery, motor with maximum horsepower, and trailer ) and multiply it by 6% on single axles and 5% on tandem axle trailers. ShoreLand’r suggests that tongue weight may be acceptable in a 5-7% range.
If the boat trailer has too little tongue weight it will tend to make a dangerous fishtail movement. This is a swaying motion that can put the towing vehicle and boat trailer out of control, leading to an overturn, skid, or overturning.
If the tongue of the trailer does not exert enough downward force on the tow vehicle’s hitch ball — meaning that the trailer’s tongue weight is too light — a dangerous condition called trailer sway could result. If the tongue weight is too heavy, the steering of the tow vehicle will be affected.
Because vehicles are specially made with set towing capacities, you can ‘t alter the rating without re-engineering the vehicle. Also, some vehicles might not be rated for towing at all. In that case, you certainly couldn’t augment their hauling power.
If you were to exceed the towing capacity of your vehicle, you probably wouldn’t be ticketed for it unless you exceeded the maximum limits under the law for your type of vehicle. For example, if you were pulling more than 80,000 pounds with a Class 8 rig without the proper permit in the US.
The way to reduce the tongue weight is to load the coach with all heavy gear over the axle and reduce the total load out to 4500 lbs. Hold your tongue weight to 450-500#s. Do not move gear to the back of the coach.
To find your truck’s towing capacity, subtract your truck’s curb weight from its Gross Combined Vehicle Weight Rating (GCVWR). The GCVWR is the maximum weight of your loaded truck and the weight of its attached trailer.
What is the first thing you should do after retrieving a boat onto a trailer? Pull the trailer well away from the boat ramp.
How can I calculate my tongue weight? Make sure your trailer is fully loaded as it would be when taking it on a trip. While the vehicle is still on the scale, unhook the trailer and lift the tongue jack high enough so that there is no weight on the hitch ball. Subtract the two weights from each other to give you your tongue weight.
To find out how much your boat and trailer weigh together, weigh your entire setup, including your tow vehicle. Then weigh the tow vehicle alone. Subtract the tow vehicle weight from your total weight, and that will give you the weight of your boat.
Expert Reply: You should have the hitch ball height set so that the trailer tows as level as possible behind your pickup. Adding weight in front of the trailer axles would be the best way to increase the tongue weight, just make sure you stay within the capacities of your towing setup.
The answer is: Avoid power loading onto the trailer. Completing the sentence: When retrieving a boat at a ramp avoid power loading onto the trailer.
Trailer Size Federal law requires that a trailer display its GVWR (Gross Vehicle Weight Rating), which is the total weight the trailer is rated to carry, including the boat, engine, gasoline (six pounds per gallon), water (eight pounds per gallon) and gear.
