Summary
On the morning of 12 January 2022, two men were found unconscious in the covered cockpit of the privately owned sports cruiser Emma Louise, which was moored in Port Hamble Marina. The men had left the boat’s petrol engine running during the previous evening, likely to maintain power to some of the boat’s systems. Exhaust gas had built up in the covered cockpit area, causing them to pass out and die due to carbon monoxide (CO) poisoning.
Safety Issues
-
Exhaust gas, containing CO, had likely been funnelled into the cockpit between the boat’s transom and an inflatable water skiing ringo suspended from it. The cockpit was covered by a close-fitting canopy and the exhaust gas accumulated as there was little ventilation to enable the CO to disperse.
-
With no CO alarm fitted on board the men were not alerted to the danger of CO poisoning before they succumbed.
-
Further work by industry stakeholders to raise CO awareness among pleasure craft users is required to reduce the increasing number of fatalities caused by CO poisoning.
