First 41S5
Lead keel

While using the principles of First 32S5 and 35S5, First 41S5 is born as a combination of the Bénéteau knowledge, the experience of architect Jean Berret and Philippe Stark design. This trio results as a boat that provides both space and sportiness. Inside the boat the finest materials and high volume are highlighted by modern design and "bionic" forms.

For her performance, First 41S5 differs from classic production: she has a large mast 7/8 held by Rod rigging, lead keel with a draft exceeding 2m – 6.6ft, composite rudder stock... all is made with permanent attention to the design, such as flush chain plates. The practical aspects are not forgotten: for example the ventilation is very well thought.
