I haven't heard of an electro hydraulic, but the standard type lift here in the USA for tidal waters uses an air pump to push the water out of the pontoons. I have kept my Nautique on one, and many friends use them. Setup is important, and simple things like balance points, and bunk location is kinda a trail and error process. It is also nice to have some way to center the boat with upright stanchions of some kind.
What about a drive on dock?
