Sorry for the delay! Here are some measurements:
Foot - 28 feet 2 inches (exact)
Luff - 63 feet (might be slightly off, measured inside the sock)
Still don’t have the sail area, it is an irregular shape and my calculus skills are weak.
Serial # of the sail - 30324
Yes it comes in the original black bag. The black bag is in fair condition, 5/10 with some fading and small tears.
Will be glad to ship but will expect you to pay
shipping. Thanks for the questions.
