I have used a vinyl covered piece of aluminum purchased from McMasters catalog. That worked great for me. Only trouble was that it came in black only. I went ahead and installed it, then puchased a FX Sails all black jolly roger sail. Final product looked great!
I am selling a 1976 Sunfish, orange hull, yellow deck, matching sail. Has all parts including mast, booms, daggerboard, rudder and tiller. Hull has had some repairs by a previous owner. Asking $600 or best offer. Contact me at cjo1023 at yahoo dot com.
