Abstract
Abstract A trailer for a pontoon boat or other multiple-hull water craft has a pair of V-shaped glide members positioned for supporting the pontoons along substantially their entire length. The glide members are covered with a fabric, such as carpet, and are provided with a plurality of rollers in the bight of the V to provide superior support and to assist in loading and unloading a craft. The glides and frame beneath are articulated so that a rear trailer portion may be pivoted to assist in loading and unloading a craft. The trailer wheels are located laterally beyond the glides to provide exceptional load stability.
