A friend of mine used a 500 or 750 lb cantilever lift that mounts onto the dock. He asked the mfg to extend the arms out from 3 feet to 8 or 9 feet. Because of the light weigh of the Hobie, the mfg had no issues with it. He has no problems to date. URL attached for photos of comparable lifts from the mfg referred to.
