Hey there All Thumbs.
I just finished reading the whole thread. You have really out in an extraordinary effort. I have recently bought a DS 20 sail# 72. Your thread has really inspired me, and just in time for weather to start cooperating with a project.
I will be trailer it back and forth to the Bay of Quinte while repairing/restoring/sailing her the summer.
BTW, where did you get the 1/4 " sheets of fiberglass?
Again great work and documentation.
