A boat hull can suffer more damage when trailered over rough roads than it does afloat in rough seas unless the trailer's rollers and bolsters are positioned so that they cushion the hull.The axles of the trailer should be positioned or the boat mounted so that around 5 to 10% of the boat's weight rests on the car's hitch.
Step2
Place your gear so that the weight is distributed equally between the stern and bow halves.Too much stern weight can make the rig fish-tail, or sway, which could be dangerous. Too much weight on the hitch can lift the car's front end, causing the headlight beams to shine too high and making steering difficult.
Step3
Trailer wheels are small and rotate fast, they build up heat on a trip and, when they are submerged during launching, they pull water through the hubs and into the bearings, check unsealed bearings and if need be then repack them with grease.
Step4
If you store your boat off-season on the trailer, block up the frame to take weight off the tires and springs. Before your first launch of the season, examine tires and spare, bearings, winch, hitch, frame, wiring, and tie-downs. For more articles like this go to:WWW.ehow.com/members/logan.html
