The question I have is, will the camber be lost at the leading edge? Will the sail be flattened by the mast or bulge out? Take Slieve's sail shape and balance...
Iself. I just got an idea: Instead of all the work of moving the whole sail forward on the mast, one can do a much simpler test: Just bring on board a thick...

You are correct. The camber is reduced. Using my example in earlier post with a 20 inch camber (i.e. right angle to the panel) and 6 inch diameter mast. I...
Hi Arne, Pushing in the belly of the sail with a stick sounds like a good idea. I don't think the effect will be subtle. The sail area in front of the stick...
Stavanger Sunday eve Iself. Now, thinking twice, I'm not sure if that stick-test I suggested is so smart after all. At least I'll have to fit a second Hong...
Thank you Arne! I need some time to examine all that and digest it but it looks like you did my homework for me. Where were you when I was in school? I...
Arne: Is it possible that the Roach on my sail might be where I will find that missing 20 sq ft? Do they calculate the roach size in determining sail...

Hi Frank, When I plan a convertion, and use the original sails draving as a guide, I always take into account thr roach unless it is very slight. Victor...

Stavanger, Wed. Robert, I've had a rethink on this and I guess I've been to categorical, dismissing the van Loan sail too much . The high balance sail would...

Well, there you go. A VanLoan shape with camber. Thanks BJ. I can barely see the camber in the pic of the sail but that's probably because it is only 5%. rself...

Hi Bernard, Thanks for the link. The 'darts' are a very interesting way of sewing camber into the sail. Great for a small-boat sail that is made from a single...

Stavanger, Sat Serge. I have written a little article called The Mast which in the end has a description of Johanna's battens and yard. You find the article...
Tank you for your reply, I must admit I am a little puzzled by the small diameter of your batten, but then the pictures of Ti Gitu speak for themselves : High...
