[quote=texastuma][quote=Kevin219][quote]To this old-time beach cat pilot, it just looks like these battens are too short.[/quote]
The battens are full length. Luff to Leech.
Revintage, I will resort to buying a stick of alum if it comes to that. Below another picture. clear to see the bottom half of the sail has 2 distinct concave sections to it.

I don't think this is a boomless issue, from a previous sailmaker POV, it's a sail design issue. Building a boomless main had challenges. I had raced a 6.0NA with a square top and it took me a couple of rounds to get the shape correct. I would suggest take pictures up the sail at about mid draft in every 5 knots of wind. Watch when the sail "flips inside out". My guess, it is about 8-10 knots of wind.
But, it would be worth trying a boom and see if you like it. On my modified 18-2, I am using a section of aluminum hand rail for decking. It's about 3"x1". And 10' sections are easily to get. I wouldn't invest a lot into it until you are satisfied with the result.[/quote]
