When choosing a boat trailer there are many factors to consider. Not all boats and launching ramps are the same. Also, boat trailers will vary in size, construction, and intended usage. You must know these key factors before choosing your new boat trailer.
The following will help you choose the right boat trailer:
Know the weight of your boat including engine(s), fuel capacity weight (full), all on-board gear and any other equipment that not include in the manufacturers specified boat weight. This weight will determine the capacity requirements of the trailer. Trailers are manufactured to carry a specific weight; manufacture specs should be followed.
Know the length of the boat from bow eye to the transom. If you have a pulpit that extends off the front of the boat you should also know the length of the pulpit as well as the length of any swim deck that extends off the transom
Choosing Aluminum or Galvanized. A Galvanized trailer offers a protective coating that in normal conditions can prevent rusting for several years. Aluminum boat trailers are very corrosion resistant and offer a light weight option. Both Galvanized boat trailers and Aluminum boat trailers perform well in salt water conditions. It is a must to rinse both styles after every use in salt water, this will ensure the maximum life span of your boat trailer.
Single or tandem axle boat trailers are available and both have advantages and disadvantages. Single axle boat trailers are lighter and can be easier to maneuver though, have lower weight capacities than tandem axle trailers. Tandem axle boat trailers have more weight capacity though, can be more difficult to back-up. If you do a lot of long distance towing, a tandem axle boat trailer can provide a safer experience in the event of a tire or hub failure.
Check brake laws in your state. The State of Florida requires brakes on all axles of any trailer with a G.V.W.R. (gross vehicle weight rating) of 3000 lbs. or more. This includes the combined weight of the trailer itself, the boat, and all equipment being towed or carried. When making a boat trailer selection, be sure you know your states laws.
