Without doubt the Grumman is a great dinghy. I rowed one years ago and loved it.
Actually, as my post implied, I am looking for a sail for a Dyer Midget dinghy for my grand daughter
I did when looking for a replacement spar for my O'Day 20. About 3 weeks went by with no response, then a guy far away from any boating area called me and had the complete unit with all the hard to locate small parts. Exact fit and in perfect working order, saved me over $1,800.
