On DeckMovable Ballast

Looking forward to seeing more on Bethwaites"LAS" but the "Martin 29er" is nothing like I propose. Stefan is right: the weight slides on a curved wing shaped appendage moving the ballast 2.43 m to weather(the whole wing moves as well). More or less equivalent to a single heavy crew on a trap standing on one meter wide wings attached at the deck edge of a 1.3m wide boat. Loads of RM!
Enough RM that ,according to Bethwaites formula the boat would theoretically be able to plane upwind.
I don't see a small high powered multi being safer than this boat! Maybe faster but this boat will be self righting-at least when configured in it's "safe mode".
I built a 14' tri a while back that you sat down inside and the sensation of being so low-with your head real close to the water is amazing-that will certainly add to the experience of sailing this boat.
Keeping the power manageable and the ballast easily under control is a challenge but I think it is feasible.

Doesn't really sound the same. If I have understood the first post in the thread, Doug is talking about something a bit IC-like, but with ballast on the plank rather than the helm.

My mistake - I forgot you quaint Americans still use Imperial units. Doesn't change the point though: 90kg of buoyancy will be bulky.

Originally posted by Doug Lord If you reread the previous post you'll notice the part about more buoyancy in the wing than weight.

And if you reread my first post, I said that enough buoyancy to counteract 200kg of ballast is going to be bulky.
