You try convincing my girlfriend i should be working on the cat again today!
There's a load of jetskis on the modular ones on the first pontoon on the north beach side and there's a jet boat at the very end of the 3rd or 4th pontoon up on the same side that's on a lift the same as the one under the sunseeker.
To be honest the best system i could see is the one under the jetskis, they do a brilliant system for monohulls up to 30ft and the best thing is it's modular so you don't have to buy a whole new one when you buy a new boat
Oh, and there's no pumps or anything involved, it just sits tere so will also be the lowest maintenance.
PM me if you want my number and i can show you how it all works...
