Today, we've published our investigation report into the man overboard from the lone-operated creel fishing vessel Sea Eagle (AH18), resulting in one presumed fatality in fishing grounds south-east of Montrose, Scotland on 20 December 2025.

* Carrying multiple strings of creels increases the risk of entanglement during shooting operations.

* Separation from fishing gear during deployment is essential.

* Interaction with running fishing gear presents a serious man overboard hazard.

* The risk of drowning is high following a man overboard event from a lone-operated fishing vessel if precautions are not taken.

* Not wearing a personal flotation device significantly reduces the chance of survival when self-recovery is not possible.

* Fatal accidents involving lone operators of fishing vessels continue to occur despite longstanding industry guidance.

Today, we've published our report and safety flyer on the investigation into the allision of the rigid inflatable boat Peaky Blinder with a navigation beacon in Portsmouth Harbour, England resulting in two fatalities on 14 August 2025.

* Drinking and driving afloat ruins lives just as much as on the road.

* Recreational boaters: stay sober, slow down, and wear a PFD every time.

* Sober operation, safe speed, and lifejacket wearing are basic protections that save lives on the water.
