Summary
Investigation into Sustain’s grounding in Loch Broom and subsequent constructive total loss. It examines the skipper’s accumulated sleep debt, overnight repairs, lone watchkeeping and navigation by eye using a magnetic-compass autopilot. Unimplemented risk controls, absent watch alarms and inadequate passage planning are analysed; the crew were evacuated unharmed.
