Summary
Investigation of Shearwater’s immobilisation and flooding near Kinlochbervie while towing Agem One. Towline fouling disabled propulsion, and repeated barge collisions breached the hull. The report examines towing suitability, crew competence, passage planning, HMPE tow arrangements, bilge pumping and regulatory oversight. The initial towline failure’s precise cause remained undetermined.
