I have a main for an Ericson 35-3. It has been in my basement for nearly 10 yrs and is in a dustproof, clear plastic bag. Age of this sail is unknown, but the boat was built in 84 so it's no older than that. When we bought the boat, 10 years ago, it had a newer full batten main on it. Unfortunately I have never actually had this sail out of the bag. It was made by Watts and appears to be in good condition (by looking through the clear plastic). I am reluctant to spread it on the lawn due to the fall leaves. I will sell it for the best offer and if you are not happy, send it back within 30 days for a full refund. You pay the shipping though, both ways.
