I can see your point, David.
I still try to fit as tall (and big) sail as I can on the shortest possible mast. However, on Johanna I overdid it a little. Besides, now, with the hybrid aluminium-spruce masts, weight is easier to keep down. On SibLim's shown mast, I guess I could increase the AR of the sail a little, maybe to 1.95 or 2.00, since the halyard drift looks so generous.
However, this was about plonking Ingeborg's rig onto SibLim's sailplan, just to see. I think the size and height of the rig you have designed for SibLim makes sense.

PS, 4.12: Now I added a sail with AR=1.95, just one notch taller than Ingeborg's sail. It is the tallest there is room for on that mast, giving a SA=36.4sqm.
