There are many talks out there about aspect ratios. Some of the guys tell the high-aspect ones are better for foiling, some others are to keep the CE low, so shorter mast and longer boom. I belong to the second group, so this sail is in that category as well.
As the first sail was made in a rush without cams and details, this one is 6 battens, 3 cams, also from different materials.
The panels are from monofilm, The head and the foot ones are technora laminate with 1.5mil film. The two big load patches on the clew connecting the 3rd and 6th battens, the luff panel, the mast sleeve fairing are from the same material.
The flying shape basically is the same as the previous one, just some small adjustments on the exit angles and added more twist. Also a moderatly different luff curve, more shape on the top, different head angle and batten placing. Also added a much bigger foot roach, as to close the gap between the sail and the board to create an endplate effect, basically made a sail what is called decksweeper in sailing.
In the loft. Same as on the first sail, some luff curve issues. Some modifications, and became much better. Just taking out some luffcurve from the top part, removed some excess material and some wrinkles.
It was a pretty short one, in a dying wind. Starting from cca 12kts and dying continuously. Delivers the power very well, after a gybe, even if the dry-gybe was missed, accelerates quite quickly. I used full outhaul upwind perhaps it was a little bit too much, but just wanted to flatten out. Downwind realesed fully. Played quite a lot with the downhaul as well.
Need some work, some small things needs to be adjusted to have more space for the cams, and some more luffcurve to be taken out from the top part. Finally ended up to redesign the luff curve and cut out a new mast sleeve and fairing. It was easier than modifying the existing one. Here is a small video about the plotter working on the sleeve.
Plan is to go testing within some days if the weather will be fine. Also the Ten-o is on the way, so soon will be a post about that as well.
Until that have nice winds and stayed tuned!
