For a new rudder made to your requirements contact Don Kiesling at surfski (at) gmail (dot) com
He can make you a surf or weedless rudder.. what ever length, angle and depth you want.... mostly.
I have a bunch and have zero regrets. Absolutely transformed my SR (gen2) in a downwind... and that's not hyperbole. They are nicely finished with a proper NACA foil shape and nicely faired leading edge... unlike almost every OEM rudde these days.
I'm not afilleated, just a very satisfied customer.
(Haha... looks like Don and I were posting at the same time..... Buy one, you won't regret it)
