This model trailer is technically a small boat trailer, but the dealer (Maximum Marine, Seaville, NJ) re-configured the bunks from parallel to perpendicular. I can easily fit 3 full size kayaks on their hulls, and probably more using a stacker system.Using a trailer is great - I was somewhat skeptical at first. In NJ tolls and bridges usually charge more for a trailer, and parking is an added concern. BUT, it is such a pleasure not hoisting the kayaks on the roof after a long day (also saving the paint from salt water and mud). Besides, you can place your paddling gear in the kayaks and save room inside your vehicle. This trailer is great - it has the larger 12" tires, so long trips in hot weather will be less of a concern. Also, if you get into a tight spot (I'm not real proficient with a trailer), you can move it around with one hand! In a pinch, it can even double as a cart!!
