As a point of interest, we got a quote from a sail loft/marine supply place for about $1000 for a new mainsail to match our old beat-up one. We decided to postpone the expense into a future year when we will be able to sail more... only got the old gal out on the water for a few days this summer. I did find an online supplier at some point that listed a white Dacron main at around $700 and a tanbark one at around $1K. Can't remember where, but I bet you could hunt it up with a little internet searching. If I find it again I will try to post here, but since we probably won't be sailing her again until next summer, I don't think I will be thinking too hard about that for a while.
