Re: my boat dances on a ball
I suspect that throwing a drogue is the easy button. that being said, a riding sail of some sort will end up as the solution.
I was out in a Bavaria 40 a few weeks ago, and experienced the same thing. My ~theory~ is that the hull is acting like an aerodynamic wing (yep, pilot in another life ). I suspect that both of the boats have similar profiles, both FARR designs. Plumb stern/bow, relatively flat hull under the water line, huge beam, limited cross section on the T-keel, coffee table rudder, and a rather large amount of real estate (sorry I don't know the term) from the water line to the deck. pictures abound of what I am talking about.
Needless to say, not a problem on an Island Packet....
of course "opinions and theories are like....everyone has one or two..."
