Hi Cool Cat,
Looks like my first post did not go through.
I own a Belize 43
and make sails
for multihulls. We have 6 designs for these boats and have designed and built everything from cross cut dacron mains to triradial dacron and Hydra Net mains. I have been recommending adding an extra batten making this a 7 full batten sail rather than the 6 full battens as the stock sails
have. These sails do not have slides between the battens. The extra slide helps to supplot the luff better and the extra batten helps to support additional roach in the upper leech that we have been offering. This improves performance over the stock mains.
Our sail loft is in St. Petersburg, Florida
and we ship through out the Caribbean
. Web site is www.calvertsails.com
