I know what a sail's aspect ratio is (Luff/Foot), and I see mentions that a high aspect ratio is more efficient than a low aspect ratio, but I cant find any real description of how high it needs to be to be considered "high aspect ratio" and how much more efficient it is.

The containerizable design I have been playing with is limited to a 34' maximum luff. I started with a 10' boom, then increased to a 12'. In an extreme case, I could increase to boom to a max of 20'. What foot length is "reasonable" for a 34' luff? Is 34:12 low aspect or high aspect.

My sail area is about 550 sq ft (for both sails combined) with a 10' luff, 650 sq ft with a 12' luff and 750 with a 14' luff; all calculated with an 80% roach. I assume the 80% figure is harder to maintain as the aspect ratio goes down.

Thanks for any feedback,
