A 17-METRE scallop dredger had to be scrapped after running aground near the entrance to Sound of Mull on August 24 last year.
A report by the Marine Accident Investigation Branch (MAIB) found the boat, the St Apollo, was off course due to sailing north of its planned route while the skipper was asleep in his bunk.
The wheelhouse watch keeper re duced his engine speed and alerted the skipper, but the vessel grounded before he reached the wheelhouse.
