    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 […]
  • Technical Papers for review and comment • Re: Howard Fund
    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 […]

    Hi Robert!Yes, it’s a great idea, but... In fact, I’m not able to put one sail directly behind the other one, with my rig. If one sail sits in the boat axis, the other one lays on windward or leeward side. So, on close reach, close hauled and let’s say, beam reach the comparison with […]
  • Technical Papers for review and comment • Re: Howard Fund
    Nice data, but how did you derive the polar for the hypothetical sloop? I have a suggestion for getting real data: in the next season, generate another set of polars with the two masts of your Duplex rig always on the centreline. I expect the sheeting won't let you simulate sailing wing and wing then, […]
