If using a vehicle bumper mounted hitch, do not exceed the weight rating of the bumper. Most importantly, the coupler size must match the size of the ball hitch. Never use a ball hitch that is too small. The size rating will be stamped on the ball. On the trailer the size will be stamped on the coupler.
Tongue weight is the weight the loaded trailer places on the towing hitch.
Too much tongue weight will cause tail dragging of the towing vehicle. Too little tongue weight will cause the trailer to sway while pulling. Couplings may work loose and should be checked frequently. Trailers should be equipped with two safety chains that are strong enough to control the trailer if the hitch or coupling breaks. Before Leaving Home All gear in the boat should be secured firmly to keep it from shifting, and should be arranged so the weight is evenly distributed.
