Our dock neighbor has Hurley davits, 10' (-ish?) RIB with 5 hp 4 stroke... says he can do it, but I don't hear about them actually using it much. I suspect (but don't know for sure) that its intimidating enough for him that it influences their use of the dinghy.
FWIW, I have the Jatco Trillogy lift on our swim platform, with the dinghy cantilevered aft so we can walk between boat and boat. The dinghy mounts from the side, and it's pretty much a one-handed job with the mounted hand-winch. Our dingy is a 10'4" RIB (310) with inner floor (135 lbs), and a new 15-hp 4-stroke electric start Suzuki (106 lbs). Plus 3-gallon fuel tank (rarely full), plus small battery (~19 lbs).
