MarsKeel Technology recently provided dissimilar metal combination keel for a 68-foot modern classic cruiser/racer working alongside a US-based designer Stephens and Waring Yacht Design and boat building company James Betts Enterprises.
The keel consists of two sections. The upper section is a hollow fabricated steel keel fin (A36/44W), and the lower section is a lead-cast bulb. The bulb is integrally cast on the fin, which is a hallmark of MarsKeel. An Integrally Cast Bulb (ICB) simplifies the casting of the bulb as no cores or holes are to be cast. It also removes the necessity for mechanical attachment to the fin.
This was a complex project because of the connection between the two materials. Through collaboration and using the combined experience of MarsKeel, the designer, and the builder, challenges were overcome to create a safe and simple design.
The result was another great success story for MarsKeel, working collectively with the Designer and the Builder to create this amazing keel.
