MAIB: Flooding and sinking of the survey workboat Bella

The survey workboat was conducting inshore hydrographic survey operations in the approaches to Lynmouth, UK. In conditions of wind force 3 from the NW, and short, choppy 1m seas, waves started breaking over the bow, beginning to fill the forward cockpit area. The skipper turned on the electric bilge pump and reversed course to the south-east in an attempt to prevent further water ingress by running down-sea. Floodwater was, by then, flowing over the sill of the forward door into the wheelhouse and from there entered the void space beneath the wheelhouse deck.
