ABSTRACT:
A launching and lift assembly for small watercraft such as a jet ski comprises a skid cradle for seating the watercraft thereon for sliding movement off an end thereof. The skid cradle is mounted on a dock for rolling movement thereon forwardly over a launching edge thereof on a rear caster and on a pair of forward support rollers secured to the dock at its launching edge, for downward tilting of the skid cradle on the support rollers over the launching edge to cause the watercraft to slide downwardly off the tilted skid cradle and into the water when the skid cradle and seated watercraft are rolled forwardly on the dock to a position wherein their center of gravity is located forwardly of the support rollers.
