Keep in mind that weight rating refers to the complete load boat, motor, fuel, water and gear so build in a cushion and estimate high. Also, choose large wheels over small ones. Since small tires make more revolutions to cover the same distance, they put more stress on the bearings. So go big. Deciding whether to get a trailer with carpeted bunks or rollers is largely a matter of preference and budget.
Rollers can be useful if a boater s primary launch ramp isn t steep or if the boat is heavy.
Otherwise, bunks work for most situations. The type of brake isn t as important as ensuring the system is in good working order. Brakes should be checked before every use. The trailer, too, should be periodically inspected for such things as loose bolts, faulty bearings, broken suspension components, damaged rails, frayed winch cable or strap and hitch integrity. Selecting a good towing vehicle these days is easy.
