VAN DER VELDEN® FLEX TUNNEL SYSTEM
The solution for efficient hull design without compromising for exceptional sailing conditions. the FLEX tunnel offers major benefits in terms of speed, loading capacity, manoeuvrability and reduced fuel consumption. The starting concept behind the Van der Velden® FLEX Tunnel is its ability to retract. With the tunnel embedded into the hull of the vessel, resistance is lowered and efficiency increased. When sailing in shallow waters the FLEX tunnel is deployed to ensure sufficient water flow to the propellers and maintain their efficiency.
