Lightweight makes all the difference when it comes to reducing fuel consumption, so, using a mere 3.3 litres/NM at 30 knots, the new Air Supported Vessel (ASV) from Tuco was built using a Divinycell core and carbon fibre laminates.
Founded in 1998 as a traditional sailing boat yard, Tuco Marine Group explains that it specialises in light structures and hulls manufactured from composite materials. Diab says that, over the years, Tuco’s focus has shifted from sailing boats towards larger structures, primarily in the commercial maritime sector, but also in other industries that benefit from low weight and high strength. With a highly skilled and experienced production team, Tuco Marine Group offers custom-built ships, but also repairs and maintenance of composite materials. Their mission is clear: “We are founded by entrepreneurs who are innovative and who want to continue being so, by developing and delivering products that weigh less, save fuels and affect our environment less.”
According to Diab, Tuco engineers decided to team up with Diab for their latest carbon sandwich Air Supported Vessel (ASV) Soft Motion Demonstrator, in collaboration with the Norwegian company Effect Ships International. Measuring 18 x 5.2 m and fitted with two small Volvo Penta IPS 600 pod drives (2 x 320 kW), the vessel benefits from the patented ASV concept, which allows it to ride on ‘a cushion of air’. It says that this solution reduces the wetted surface area and hull/water resistance to a minimum. During tests, and prior to any optimisation work, Diab claims that the ASV reached a speed of 37.2 knots. But even more remarkable was the fuel consumption. At a speed of 25 knots, the overall consumption was a mere 3.0 liters/NM, including propulsion and lift fan powering. This impressive feat was made possible through its light-weight sandwich construction, with Divinycell core and carbon fibre laminates.
