Our personal water craft lifts are available as either single (1000# or 1500# capacity) or double (2000# cap) lifts. The double PWC lift has 2 sets of bunks on 1 carriage. The bunks are set at 2 different heights, so that 1 PWC will float off first (if you are only using 1) and the 2nd would stay high and dry unless you continue to lower the carriage. Canopies are available for both the single or double lifts
