Petit Plateau
As a user of both Ampair and Aquair on my boat, I am very enlightened to read about the inventor.
I have to say that the Aquair does need a rethink though - the trailing line is vulnerable and cumbersome. I've cobbled together a prototype that uses a dog-legged geared impeller that mounts on the bathing platform so that the impeller sits just behind the rudder. It is a more compact arrangement that can be deployed more easily, does not get bitten off by inquisitive white tip sharks, and does not tangle in the fishing line. It could do with some tidying up for production - pm me if interested!
