1, Boat Trailer Styles - There are two types of boat trailers: bunk-style and roller-style. Each type has its own advantages and disadvantages, depending on a boater’s particular needs.
2, Boat Trailer Materials - The boat trailer materials are constructed from three types of materials. The materials we use to fabricate boat trailer are aluminum or mild Steel I beam trailer, C channel and tubular box frame. Any of the above mentioned items are used to fabricate trailers.
ii, Tubular box frame trailer - Steel tubes are preferred for two reasons they are lighter compared to other trailers and can store electrical wire which can protect the wires and brake lines as they can be stored inside the tubes of the frame. These type of trailers are very useful for bunk style trailers which are usually submerged in water.
iii, C-channel Boat Trailers - These C-channel boat trailers are less expensive compared to other types as they made of steel which is comparatively cheaper but as aluminum requires extra steps to protect the electrical components from exposure to the water.
The other main factors which are very important to determine a boat trailer are length of the boat, boat capacity or weight and waterline width of the boat.
4, Boat Capacity - To calculate the boat capacity/weight or Gross Vehicle Weight Rating (GVWR), it is important to know and calculate the total capacity of the boat which includes the engine, full fuel, full water tank (also known as wet weight) and the weight of the personal items (food, accessories etc.). It is recommended to use 10% of boat, motor, and liquid weights for personal gear. Selecting a trailer with the next highest capacity rating is important for stability of the trailer. If you find that weight of th eboat is more than 3500 pounds it would be very advisable to invest in double axle (tandem) than single axle trailers.
5, Boat Waterline width - Measuring just the length is not enough, it is important to also know the areas of hull support and rollers make it much easier for loading and offloading the ramp with a gentle slope. make sure to ask width of the boat and add additional lengths if you add anything extra in the boat.
6, Boat trailer brakes -The laws vary from region to region but if your boat weighs more than 1500 pounds, it is highy recommended to get brakes on the trailers. In UAE it is mandatory to have brakes on trailers above 1500 pounds for safety and stability reasons. Most countries refer boat weights as Gross Vehicle Weight Rating (GVWR) to determine the requirements of brake. It is highly recommended to have brakes on the trailer for safety reasons.
