How much does your level fluctuate? Is it daily or over the course of the summer? Properly set up a standing lift can be easily moved with boat lift helper, (air bag system). also aids in moving to shore to remove at end of season, provided the fluctuation is over time, not tidal.
My lift goes in in May and out when kids leave for school in Sept. I have had Harbormaster canativer lift, Nyman water lift, vertical Shoremaster, and now a Floe. I like the ease of leveling the flow. The quietness of the screw jack 24v dc motor and with a canopy my boat stays dry and uncovered all season without the sun beating on the interior.
Having had countless lifts and boats on them over the years I have never had any hull damage issues. My bunk placement mimics the trailer spacing.
I have a beach/boat ramp on my property. With a crank up pontoon trailer, seasonal launching and removing are a one man operation.
I've only seen Hydro Hoist used in a marina setting where water was calm so I can't offer any help there.
