Tolly, there will be a huge faction here who will insist that on a boat the size of yours, it must be a cruising laminate.

Perhaps so.

However, ours is a 46 foot mono--so a different kettle of fish from your boat. We are moderately particular about our sails, more so than most long term cruisers. Ten years ago, we had made a dacron tri-radial genoa. It is probably going to be replaced later this year. I feel we've had very good use out of it, but it is beginning to show signs of having stretched. It was made in Australia for use there, and is our light air headsail; we are careful to furl it at 20 k. apparent, often by 18. Then we switch to our staysail.

Good luck with your choice, if you're planning a circumnavigation, you'll want sails to handle a wide variety of conditions. On a 50 foot boat, such sails are heavy and inconvenient to change. Confer with as many sailmakers as possible.

Actually, there's one here on CF, Totem, maybe you could PM him. He does not "have a dog in the fight", as they are out cruising, but is aware of current advances in sailcloth as well as being familiar with many types of boats.
