Abstract
A watercraft lift with translating bunks supported by a base frame and having rollers mounted to the base frame to initially raises the watercraft upward when driven onto the lift sufficiently to be positioned above the bunks when in their lowered position and thereby permit operation of the lift in water too shallow for use of the bunks by themselves. The rollers are positioned relative to the translating bunks such that when the bunks are in their lowered position and the lift is used in sufficiently shallow water, the watercraft driven onto the lift initially engages the rollers, which lift the watercraft upward above the height when floating in the water and above the height of the bunks. The translating bunks are then used to lift the watercraft off of the rollers and upward to a raised position above the water.
