Rather than confuse the recent topic about sails for the N26, I thought I'd start one on sails for the N31. I'm interested in what sails N31 owners are buying, and sail trim ideas that are working for you.
Stuart, can you tell us a little bit about the requirements you had for your new sail from Vermont Sailing Partners and the product you selected? I would like to get a performance oriented #1 for my N31 - I seem mainly race the boat although I also day sail and cruise - and am curious what you and your sailmaker ended up with.
My current head sail is a North radial dacron that measures about 140%. Because the chainplates are outboard on the N31, the sheeting angle seems really wide even using the inner genoa car track. And because the roller furler weight dacron is relatively heavy, and the sail has a UV scrim on the leech, light air performance is compromised when the #1 really is needed.
I do like my North radial dacron main which has a very smooth shape. After putting more prebend into the mast, the sail seems to flatten out better when we tighten the backstay. The upside is that when we furl the 140 to around 105% and and really flatten out the main, we have been able to move up the wind speed we can carry a bigger sail plan. The sailmaker sold me full battens but I'm still undecided on that feature as it makes hoisting and sail shaping more difficult.
The North V1.5 airex spinnaker works well, too. Because the forward lower prevents the pole from coming back to perpendicular to the midline, the V1.5, which is a semi-reaching cut, seems to be the right cut for the boat and the boat has good down wind speed.
What's working for you?
