Basalt composite is used for trimarans in France

France located Sardine Run boatyard has launched Sardine Run 19t trimaran with basalt fabrics in its construction. Plans for the future include designing and building completely composite trimaran with basalt fiber reinforcement.

The boatyard owner Allel Behidj got committed to basal fiber due to the excellent properties of this material. He stressed good drapability, good resin absorption, better mechanical properties and, of course, sustainability of basalt fiber in the email he sent to us.

“I am a pragmatic boatbuilder and building this boat was a gamble. Now it seems it is a winning gamble!”, stressed Allel in his letter.

Allel Behidj launched his company in a town of Saint-Hilaire-de-Chaléons on the Atlantic Ocean coast where he decided to implement his knowledge and experience gained during seven years of working for shipyards in France.

Sardine Run 19t trimaran was made from 6mm plywood reinforced with basalt fabrics from Basaltex. The hull and floats were draped with satin – 300gr /m² and bi-axis fabric 450gr/ m² was applied for fillet reinforcement. The main bulkheads were made by combining basalt and carbon fiber. However, the company goal is to reduce the use of carbon in the next models.

In my point of view, the mechanical benefits exceed the price increase, the basalt fiber improves the ratio weight v’s solidity. It’s an interesting alternative to glass and it fills the gap between glass and carbon fiber.

Allel promises to make the next trimaran 100% composite, combining standard basalt fiber, high-performance basalt fiber (FILAVA from Isomatex), and PET recycled foam.

Unfortunately, Allel stresses, French boat building community is very conservative, not very curious. They traditionally use glass and carbon. But he is convinced that basalt fiber has a good potential!
