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. Key Requirements: - The hinge must be durable, specifically designed to resist cracking, deforming, or detaching under stress. - It should withstand exposure to water without degrading. - Ideally, you should have experience with high-performance materials, particularly urethane or similar polymers. Please provide samples or evidence of previous work with high-durability hinges or similar applications. Thank you!
