These Byelaws regulate areas of land, foreshore and sea known as the British Underwater Test and Evaluation Centre (“BUTEC”). This comprises the BUTEC Base Area at the Kyle of Lockalsh and the BUTEC Sea Ranges, between the isle of Raasay and Applecross on the mainland. They are shown on the Byelaws Location Maps 1 and 2 set out in Schedule 1. The location of numbered points shown on Maps 1 and 2 on the boundary of the BUTEC Base Area and BUTEC Sea Ranges are set out in the tables in Schedule 2. Table 3 in Schedule 2 gives the location of numbered points shown on Map 1 on the boundary of the inner sea area. Different byelaws apply to different parts of these 2 areas.
