A boat cradle has two pair of channels comprised of two lower channels supporting two upper channels. The lower channel members are each pivotally fixed to its own upright; the upper channels support a plastic pad that rotates to match the bottom and the inclination of the boat. One of the inner ends of the lower channels mounts a transfer block, and the other mounts a transfer plate. The lower channels are kept generally to a horizontal position by a leaf spring; one end bearing against the bottom of the web of the lower channels and the other end fixed to the upright post. A cut out on the upright post limits the lower pair of supports beyond the horizontal in an upward direction.
