The RIBs of Exercise Rigid Lion set off from Southampton on 7 August and travelled clockwise around mainland Britain with refuelling stops in Cornwal, Liverpool, Leith and London. It is believed this is the first time a novice crew had ever attempted the passage running against all prevailing winds and tides and without the help of a 'mother craft'. The soldiers were at sea for up to 12 hours each day, starting as early as 0130 hours and covering up to 250 miles by mid-afternoon. The boats were able to communicate via an Icom supplied IC-M503 marine VHF transceiver and DS-100 DSC safety units in each boat. The equipment not only ensured the RIBs could communicate with one another but also allowed them to speak with HM Coastguard and the emergency services in order to provide a high level of safety should an emergency arise.
