Abstract
An improved floating boat lift incorporates a passive hydraulic pivoting lift mechanism, onto which a boat can be driven and positioned ready for storage using only the motive power of the boat itself. The passive hydraulic pivoting lift mechanism provides mechanical advantage in the pivoting action of the apparatus by way of passive hydraulic action, while at the same time dampening pivoting of the apparatus. Embodiments further provide means for adjusting the elevation of the pivot point relative to the surface of the body of water by way of adjusting the buoyancy of the pivoting lift mechanism.
