<DIV></DIV>Roger, 
<DIV></DIV>
<DIV></DIV>IACC is an open development class. So the syndicates can pretty much do anything they want within the limits of the class rule. There have been some interesting innovations in rigging as well as hull and keel design for these boats. There does seem to be a trend toward loose footed sails with the new materials though. Seems like you would get a more consistant foil shape at the lower edge of the sail for better laminar flow at the expense of losing the end plate effect of the boom. The tradeoffs are probably pretty subtle.

<DIV></DIV>Michael &amp; Razz, 
<DIV></DIV>
<DIV></DIV>The mainsail on Tele 2 in the enclosed picture is definitely loose footed. However, the mainsail on Stars &amp; Stripes in the picture in the September, 2002 issue of SAIL magazine is definitely not loose footed. This is probably an evolving area of design &amp; the issue is not settled in the IACC. I'm surprised the IACC sailmakers would even consider loose footed mainsails, but your picture clearly shows they are. As I said in my previous post, I stand corrected on loose footed mainsails.

<DIV></DIV>IACC class (America's Cup) boats have loose footed mains.

<DIV></DIV>Richard, 
<DIV></DIV>
<DIV></DIV>Bullshit! To the best of my knowledge, there isn't a single performance oriented sailboat racing class that prefers to use loose footed mainsails. I don't know why Doyle has made this marketing decision. Fortunately, there are plenty of other choices of sailmakers &amp; I would run, not walk, away from this idiot at Doyle.

<DIV></DIV>The mainsail on my boat is pretty much shot also. My boat is a re-mfg 1990 and I insisted on the old style spars (non IMF) and the sail I have is all that Stan had. I got in touch with Doyle regarding a new main the sail they suggust has 2 full length battens at the head and 2 partial battens towards the foot. 
<DIV></DIV>
<DIV></DIV>The sail they quoted was also loose footed! When I expressed surprise I was told that (Doyle) was no longer building mains with bolt ropes along the foot. There contention is that a loose footed sail set's better and last longer.
