Sustainable Yacht Design, Eco-Friendly, Excess Catamarans Deck Cork Alternative Option Cork Decking

As a part of Excess Catamarans’ overall goal of sustainable boat building and operating, the brand has potentially identified a new resourceful way to reduce its footprint. Part of Group Beneteau, the popular multihull brand does considerable research into product development and carbon footprint reduction. The group takes pride in being the leader in corporate social responsibility, a large part of that being sustainability.

In the effort of achieving a superior product with a reduced environmental impact, the Excess brand has identified a new solution in their decking materials – cork.

Advantages of the New Excess Catamaran Sustainable Decking Option


The natural softness of cork gives it superb non-slip properties. The texture remains consistent in both extremes of temperature and wet conditions.


Despite its soft texture, cork is a proven champion of holding back water – or wine.

Thermal Comfort

Even after constant heat, cork does not heat up to an uncomfortable point. This is due to a very low coefficient of heat transmission.

Sound insulation

The texture and perforations in cork make it acoustically superior for dampening sounds like footsteps and voices.


Cork is almost twice as light as a comparable exotic wood or synthetic decking material.


Cork has very strong impact resistance and a unique property to retrieve its original shape.


The bark of cork oak trees is harvested every 9 years, and naturally renews itself without cutting down the tree. A single tree can supply 10 to 12 crops. This makes it a legitimately renewable resource. At the core of Groupe Beneteau’s corporate social responsibility is sustainable boatbuilding, and projects like this sustainable decking one are of critical importance to explore potential solutions to leave a positive legacy on the boat building industry. This comes in the wake of Excess Catamarans’ last sustainability project, the award winning the “Deep Blue” collaborative project with Torqeedo. In September of 2021 the two innovative brands put heads together to create an electric propulsion system running off of BMW lithium-ion batteries.
