Abstract
A boat trailer is disclosed, having a rigid frame, a guide member adapted for guiding a boat being loaded onto or launched from the trailer, and buoyant members for elevating the guide member to an altitude proximate a surface level of a body of water into which the trailer has been driven. The trailer may include a subframe pivotally mounted to the main frame. The guide member, which may be a pair of cables trained over a plurality of upright stanchions mounted on the frame, defines a "V"-shaped channel dimensioned to receive and guide a boat. The subframe may be fitted with low density material blocks which upon being placed in water effect a hydrostatically-induced, buoyant force against the subframe causing that subframe to rise as it pivots about its frame mounting. The trailer is adapted for forming an automatic connection with an incoming boat and further, for automatically uncoupling itself from a boat being launched. The trailer is thereby suited for one-man loading and launching operations.
