Two rescue craft went aground near the harbour at Aberdeen, Scotland.   The first boat had been launched by the 82 meter long supply vessel Grampian Talisker when the boat lost power.   The boat drifted until was aground on the rocks near the shoreline.   A second boat was launched to come to the aid of the first.   However, the second boat also ran aground as the tide receded.  No reports of injuries to the eight crewmen on board the two boats.   Reports state the boat was performing a routine exercise.   The vessels will be recovered when sea conditions allow.
