In this special episode, Revista Náutica visits the legendary Hélices Hoffmann factory in Itajaí (SC) to show how boat propellers are made. Founded in 1937 by Emílio Hoffmann, the company is a reference in precision, performance and tradition in the nautical sector. Under the visionary leadership of Reimar Hoffmann, and now with naval engineer Bethina Hoffmann at the helm, Hélices Hoffmann combines technical knowledge and innovation — without giving up the legacy of almost 90 years of history. In this video, you will discover: ✔️ What the entire propeller manufacturing process is like ✔️ Why an incorrectly sized propeller can make your boat less efficient ✔️ What is the secret behind propellers ✔️ And what makes Hoffmann a partner of major Brazilian shipyards Each propeller is custom-made, with noble materials such as bronze and Nibral — a patented alloy that combines nickel, bronze and aluminum. “There is no magic propeller”, as Bethina says — but there is science, calculation, sea trials and a lot of history behind each piece. Watch now and understand why Hoffmann is much more than a factory: it is part of the DNA of Brazilian navigation.
