Durable Urethane Hinge for Sailboat Rudder

I'm looking for a skilled material engineer or specialist to create a 12-inch urethane hinge for a small sailboat rudder. This hinge will need to withstand high-stress conditions and is intended to replace an old, degraded hinge that turned into a slippery goo after 20 years...
