I want one too!! I saw a 560 in St. Maarten several years ago and the captain
blasted around the boat, two second maneuver, and up he and the boat came. It was really impressive.
Having said that, the span between my hulls would only accomodate a 12 or 13 foot rib
and if I was going to such an expense, it would be for a 15' rib
with a jockey seat. What I've been thinking is to put a solid platform on the back like a Voyage or St. Francis and use a deck
crane. They don't weigh much, cost less then the raising platform, and would allow the bigger rib.
