| It's a weight thing mainly. But longer boats will usually weigh more, so that's why you see tandem axles on the boats 19 on up.
Single axle trailers can go as high as 3400 Lb. Tandem axle trailers usually start at 4000 lb.
The trailer not only has to be long enough and wide enough for your boat, but must be able to carry the weight of the boat and everything in the boat, including motor(s], fuel, water, personal gear, and other items that you may have on board. This final weight is called wet weight’ and cannot exceed the carrying capacity of the trailer. The GVWR [Gross Vehicle Weight Rating] listed for the trailer, is the maximum amount that the boat and trailer combined can weigh.
Tandem axle trailers nearly all come with brakes. I highly recommend brakes on a single axle trailer if the GVRW exceeds 1500 lbs. Just makes it safer to tow.
Biggest draw back to tandem axle is lack of manueverability when not on the tow vehicle. Tough to move them around by hand. Other than that, I loved my tandem axle trailers.
I also like bunks over rollers. |
