Technical Papers for review and comment • Re: Howard Fund
Unfortunately I’m not able to do that due to the location of main sheet holding point.But it’s not so important afterward. But, what is surprising with this boat, is that he is faster before wind! And that’s incredible! So I try to figure how and I find that the drag coefficient of the sails configuration […]

I forgot that the masts are a bit ahead of the rotation axis.Even so, can the rig be rotated so far that the forward and aft sails are along a line parallel to the centreline? Could the forward sail be sheeted in far enough for upwind work? That should still be the closest comparison to […]

I expect the sheeting won't let you simulate sailing wing and wing then, […]
