Re: Yet another roller furling question
When you order new sails the sail maker should come out and measure the boat. This will allow them to make a sail that fits perfectly. I had a new genoa made recently and I love seeing how perfectly it fits the boat. The height of the foot off of the deck is perfect to keep it low enough for good performance and high enough to not get tangled up in the lifelines.
That said, a smaller jib (like a working jib on a boat designed for larger overlapping headsails) may be purposefully cut with a shorter luff.
It sounds like your sail was probably found on the used market and made to fit. There is nothing wrong with doing this to save some money, but a custom cut sail will fit better. It's like the difference between buying off the shelf pants vs having a tailored suit.
