ABSTRACT:
A trailer for carrying a centerboard type sailboat behind a towing vehicle. The trailer includes longitudinally flexible bunks that receive and conform intimately to the hull configuration on opposite sides of the longitudinal boat center line. A walking beam arrangement is located between the bunks and carrying frame to enable free flexing of the bunks while transferring weight of the boat to the framework. The longitudinal resiliency of the bunks enables loading and unloading of the sailboat in relatively shallow water and further facilitates even distribution of the sailboat weight over the entire bunk surface engaged therewith.
