Summary
Investigates Elhanan T’s flooding and sinking off Fraserburgh following compression-fitting failure and ineffective valve isolation. Examines bilge pumping, watertight subdivision and maintenance, alongside rescue communications and the transition to salvage. Releasing the nets altered stability, causing capsize; the skipper and helicopter winchman were subsequently recovered without injury.
