I have a roller-furling main on my Hunter 290, and as much as I love the convenience, the light air of August and September have given me pause to consider a 'club mainsail' (a full roach second sail). The Edson mast has a second track, presumably for this purpose. When I went to my owners manual, I found two pictures - one for the standard sail plan; one for the furling plan. The mast is taller with the furling option, hence a longer "P". The jib dimensions are the same. However, the jib area is shown as 176 sq ft for the standard plan and 189.7 sq ft for the furling option (I=32; j=11, which works out to be 176). First question - for those who have a furling option, is there a bigger jib (presumably to offset the smaller mailsail)? With the taller mast, I'm guessing the "I" is actually a little longer but listed incorrectly in the furling sail plan. Second question - and I've searched the archives - has anyone considered a "club mainsail"; a full roach mainsail for use on lighter air days (or for club racing)? I am researching vertical battens and swing batten options for a new mainsail, but thought I might go right at the problem (and with a taller mast, even get away with a bigger-than-normal mainsail). Regardless of your boat size, for those with a furling option, could you check your owners manual and let me know 1) if there is a difference in the jib sizing, and 2) whether a club mainsail makes any sense? Thanks.
