in a special camp at the James Sutherland Herring Factory in Lerwick, administered by James Adie and his Norwegian-born wife. Facilities The lack of a slipway and other repair facilities meant that at first the boats had to be repaired at Malakoff's in Lerwick. Later, they moved the boats and crews to Scalloway, where William Moore & Son had a mechanical workshop and where "Prince Olav's Slipway" was built. Harald Angeltveit and Johan Haldorsen were the head mechanics and Severin Roald became leader of the carpenters. All ship repairs were done there but Lunna Voe was still used for preparing special operations. Dinapore House was headquarters for the base in Scalloway, while Flemington House became quarters for agents awaiting transport to Norway and for de-brief on return. A former net loft, owned by Nicolson & Co. became accommodation for the boat crews and was named "Norway House". Sevrin Roald's wife, Inga Roald, was the housekeeper. Flemington House was also on occasion visited by high-ranking officers like the Commander-in-chief, Scottish Command and the Admiral Commanding Orkney and Shetland. The most prominent guest was HKH Crown Prince Olav of Norway who visited in October 1942. Mitchell left the base in Scalloway in December 1942 and Captain Arthur William Sclater, known as "Rogers", became leader of operations; his Norwegian-born wife, Alice, acted as welfare officer for the crews. Operations At first, there were fourteen fishing boats of various sizes. The original Shetland Bus boat, the Aksel, skippered by August Nærøy, departed for Bergen from Hamna Voe, on the west side of Lunna Ness, on 30 August 1941. The other crew on this first tour were Mindor Berge, Ivar Brekke, Andreas Gjertsen, and Bård Grotle. Fishing boats were used at first, but after some losses, it was decided that faster vessels were necessary. On 26 October 1943, the US Navy officially transferred the submarine chasers Hitra, Vigra, and Hessa to the Shetland Bus operation. These craft were long and powered by two 1,200 hp diesel engines, capable of a top speed of , with a normal cruising speed of . When the submarine chasers arrived, the group became an official part of the Royal Norwegian Navy and was renamed the Royal Norwegian Naval Special Unit (RNNSU). KNM Hitra was commanded by Ingvald Eidsheim. Vigra was commanded by Leif Larsen. Hessa was commanded by Petter Salen. They carried out more than 100 tours to Norway,
