Westlands had intended to follow the SR.N3 with a large craft, the SR.N4, but this was delayed until the skirts equipped on the SR.N1 and SR.N5 had been fully developed and tested. In 1965, the project was authorised and work was started. Despite the Saunders-Roe company merging with Vickers Supermarine in December 1966, forming the British Hovercraft Corporation Ltd and causing Sir Christopher Cockerell's resignation, work continued, and the first began trials in 1967. The SR.N4, known as the Mountbatten class, was the world's largest hovercraft, capable of carrying 254 passengers and 30 cars across the channel in half an hour. It was 200 tons, and had a top speed of 83 knots7. The SR.N4's propellers have a diameter of 21 feet, making them the largest driven propellers in the world. The hovercraft's fuel is kerosene, which is the same fuel as an airliner. It cost £1.75 million and was fitted with a skirt that was 2.5 metres high, which was expected to cope with most conditions in the Channel. It underwent 2 hours 30 minutes of trials, covering a distance of 20 miles and reaching speeds approaching 50 knots - this in winds gusting to force 6. The world's first hovercraft car ferry made its maiden flight from Dover to Boulogne on 11th June, crossing in 35 minutes. This not only captured the public imagination, but the British Government also instructed British Rail to set up a hovercraft subsidiary and introduce an Isle of Wight route prior to taking delivery of the first SR.N4 for cross-Channel services in 1968. It was soon realised that the skirt system still had not been perfected, and by 1976 the skirts were replaced. The new skirt, when inflated, raised the craft 3 metres into the air. The SRN.4s were also stretched by 55 ft. This increased passenger accommodation to 418 and the car capacity increased to 60. It now had a displacement of 300 tons. The SR.N4 was now nicknamed "Super 4". It is the largest hovercraft in the world ever, and in 1978 the Cowes, Isle of Wight workcrew were awarded the 1978 Award for Innovation. |
