I would first get myself a good book on the theory and practise of sailing
and learn a bit about sail performance and terminology. You seem to be a bit
mixed up in your terms.

A 135% genoa (any good sailing theory book will explain how this is
measured) is generally the best all around compromise. If you generally sail
in light air, a 150% might be better. If you routinely sail in heavy wind, a
100-120% would be better.

Thanks, I'll get one of those books right away. In fact I have a friend
who has one. I'll need to borrow it if I want to beat him racing.

But I need to make this sail decision day after tomorrow, for the free
storm jib, and I thought someone might have a quick forumula for the
measurements a storm jib should be, or any jib/genoa if someone can.
That will be in the book? I can get it right away, I guess.

I'll know the height of my mast, the length of the boom, etc. I'll
investigate much further before buying any sails later.
