Hi,
I have a White Quicksilver 340 Airdeck. As a spare so I launch where there is no local slipway for the rib, (NW-Scotland).
I have used it with a 6hp Engine , which is only Just enough to plane it with me and my youngest on board , I think a 9.9 would suit one quite well, with 2 on board.
Build quality is Very Good. and overall package Quite Light and easy to transport.
That's about all I have to Say .
(Which is a bit unusual)
