In July 2022 the MCA issued MGN 653 (M) Electric vehicles onboard passenger roll-on/rolloff (ro-ro) ferries. Whilst this has limited application to yachts the provisions in guidance paragraph 3.9 could be useful where yachts carry electrical equipment in a drive to be more environmentally friendly.
3.9 The crew involved in car deck inspections may be supplied with and trained in the use of thermal imaging cameras. This should be included if charging is permitted onboard. These can be used to check floor pans of electric vehicles to detect any overheating, before embarking and during crossings. Increase in battery temperature will be anticipated during charging so care should be taken in determining what temperature rise should trigger alarms. Thermal imaging investigations should be undertaken if there are any concerns over a vehicle raised by the fire patrol. Early warning of overheating vehicles may be possible with periodic use of thermal imaging cameras and recording of results. Manufacturers estimate that the minimum temperature in the battery w
