ABSTRACT:
A boat trailer for loading, transporting and launching a boat includes a wheel-supported frame having a pair of longitudinally-extending frame rails. A transversely-extending aft support cradle is connected to the frame rails and is arranged to pivot relative to the rails in forward and rearward directions to facilitate loading and launching of a boat. The cradle is of a U-shaped configuration, having a pair of support arms which extend upwardly at opposite ends of a cross-beam. The support arms overlie side portions of the frame rails and are pivotally connected to the frame rails near upper surfaces thereof. The cradle carries at least one longitudinally extending rocker arm which supports hull engagement rollers. The pivotal connections between the support arms and the frame rails are located relatively high with respect to the locations of the hull engagement rollers. During boat launching, the cradle swings forwardly, causing the rollers to move forwardly in unison relative to the trailer frame to help "uncradle" the boat. During boat recovery, the cradle swings rearwardly, causing the rollers to move rearwardly in unison relative to the trailer frame to better "cradle" the boat.
