Steve, Thanks for sharing your extensive knowledge and experience in your book series. Accompanied by your videos, they are assisting us in mastering the significant learning curve. Last year, after careful consideration of your discussion of maxi roach full batten mainsails, we made the jump and invested in a new main and car system for our Endeavor 38. Wow! A substantial increase in performance, plus a new sense of confidence in a wide variety of sailing conditions. The new main provides enough drive that we routinely use a much smaller headsail and we have reduced weather helm. However, our battens continue to be a source of frustration. When reefing, furling, or raising the mainsail, the battens bend and flop out of the lazy jacks, dragging the rear third of the sail material with them.
In addition, starting in moderate air, the battens seem to be overly flexible and don’t seem to respond enough when flattening the sail. Additionally, the battens donÕt appear to be stiff enough to control the sailcloth as the main lays on the boom. Our initial diagnosis is that the battens are not stiff enough given the sail size, aggressive roach, and cloth weight (7.5 oz). The fundamental question is how do you tell when you have arrived at the right batten stiffness? I suspect our sailmakerÕs choice of batten material (pultruded 1 5/8Ó glass) was based on the availability of standard materials. If the analysis is correct, what is a source for stiffer battens?
