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 identified a new resourceful way to reduce its footprint. As a part of Group Beneteau, the multihull brand does considerable research into product development and footprint reduction.

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 Deck 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.

Stay tuned for more information as this option goes into further testing.
