SAFETY AT SEA: Heavy Rescue Boats

The investigation report stemmed from an accident wherein a fast rescue boat being used by the crew of a cargo ship fell 29 metres to the water when the line parted. The probe determined that the crew was not aware that the boat was much heavier than designed because of water ingress in the foam lining.

The agency urged crews and operators to inspect their rescue boats' boats' hulls and exposed decks for possible holes, cracks, or fittings through which water could penetrate, and ensure that drain plugs fitted to the hull are regularly opened.

" Monitor boat performance for unusual characteristics that could be attributed to an increase in weight, eg that it does not feel 'heavy' or 'sluggish' when manoeuvering," the MAIB report said.
