Re: V hulls and center of resistance

"Grona Jr, Robert J."
>I agree with what you say about the flat bottom low rocker boats
being more suitable for the more European rigs and lifting rigs such
as the Gibbons or Pacific Lateen for the sharper bottom higher rocker
hulls. My leanings for the former is a schooner rig based on two
windsurfer type rigs, one at each crossbeam. This would shift the
centre of effort of the sails forward from that of a single una rig
and also reduce the stresses at the centre of the hull and decrease
the righting moment needed.
For my own V-bottommed asymmetrical outrigger,it has little rocker
but still should be weight sensitive for steering I was wanting a
boat I could sail or paddle, with no holes through the bottom, no
rudders and a rig I could take down at sea while I went snorkelling
or fishing. An old windsurfer rig is available immediately and so I
can get sailing. I will probably have to move the base of the mast
during a shunt to get balance so I still think a Pacific lateen rig
is probably a better bet for this type of craft. I have doubts about
the reefing ability of the Gibbons rig.

Jim, Don't think you can mix and match hulls and rigs. The Gibbons and the EasyRig are different solutions to their respective hull forms. HarryProa is unique...

Hello, Bob G. Your observation of differences between harry's lee hull and deep-v hull is correct, but the theory could need some define. Let's look the hull...
