Thats very interesting to hear. My local marina is offering me a deal on a new one but I have never seen them in the flesh. My concern was getting on and off and how easy/hard that would be. For an 8.5 metre rib with O?B they are quoting just shy of £5k fitted. A good £4k less than a comparable hydrohoist.
Apparently some marina's dont like them as they cannot use your bearth when you are away, which is a p!ss take considering you pay for it for a year anyway!!
