Project

Mass reduction of Sailing Yacht Composite Bowsprit by 65%

Designing a very fast and at the same time easy to handle sailing yacht is a very challenging task. The structural design of the hull and all attached parts implies two conflicting objectives, which both have to be met, creating a structure which offers
the highest possible stiffness while also being as light as possible.

This challenge is allways present when we work for our client, Juan Yacht Design.

As a case of success we show you the analysisand the structural design optimization of the sailing yacht bowsprit of carbon fiber.

Structural optimization

The challenge of this project was to reduce the weight of the bowsprit while keeping stiffness properties as high as possible. These conflicting objectives can only be met using composite material and a dedicated optimization technology, applied to the layout of the composite material and the component’s shape. The design and optimization of composites
presents its own unique challenges because the engineers have to take the characteristics of the material into account to leverage its lightweight and stiffness potential.

The bowsprit bears the rigging loads and, because the walls are thin to keep the weight as low as possible, buckling modes also have to be considered. In the development process, the engineers therefore had to combine buckling, pretension, and topology optimization to design and optimize the composite part.

Thanks to this process, a piece 34 kg lighter than the previous model has been designed, with a final weight of 19 kg, which means a reduction of almost 65% of the weight.
