Only short notice given, substantially as follows: New multiaxial carbon fibre fabrics are now being employed in commercial passenger ferries for use in the Norwegian fjords. Using multiaxial fabrics over a core material, Brodrene has now produced the Rygerkatt - a boat designed as a harbour passenger ferry, which will make an average of 200 stops a day carrying up to 62 passengers. At 18.5 metres in length, 7.5 metres wide and weighing just 27 metric tons, the use of carbon fibre materials has resulted in a structural weight reduction of 40 % over traditional composite materials that would have been employed in the boat's construction, the company says. With the increased strength and reduced weight achieved by using these fabrics the boat has a top speed of 29 knots and an operational speed of 24.9 knots. At normal operating speeds the ferry requires 5.90 litres of fuel per nautical mile. The Rygerkatt is number two in a commercial series that was launched with the Ryger Doktoren a high performance ambulance boat with a top speed of 44 knots. The design criteria behind this model were the same as for the Rygerkatt, but the weight savings were used to achieve higher speed.
