I have some problems to find the right mast for my Vapor 12.0 Technora. I think the mast I use (North 550 100% carbon) has to much top flex. The leech is very loose between the two upper battens compared to the battens below. The recommended setting is 584 cm , but it seems to give the sail not the required downhaul; 588 seems to be better.
My questions are:
Wich bentcurve and wich IMCS is needed.
Which battens has to fall down ; how to trim the sail (downhaul and outhaul).
Hope that one of the team members can answer, especially Ross has used the 12.0 in Formula!!
