The GV10 is my design that is for sale at www.bateau.com. I've designed a number of stitch and glue boats for that site, and the owner Jacques has done many more. Check it out sometime.
The outside seams are done; another 3-1/2 hours. Total time is 14-3/4 hours. The temperatures in my friend's garage are rather cold - epoxy put on one night is still quite sticky the next night.
