Profile: Duncan Propellers Ltd. is a provider of propellers. We specialize in the design and manufacture of marine propellers & stern-gear systems. We enhance with design, pattern-making, foundry, machining, finishing and inspection services. We cover applications like naval vessels, super yachts, fast patrol boats, lifeboats and coast-guard vessels. The new form of our custom designed propeller uses blade geometry which produces optimum flow for smooth and efficient thrust. Our foundry is equipped with new electric induction melting furnaces for cleaner and purer castings. We also produce stern-gear castings such as rudders, shaft-brackets and shaft-bearing housings.
