On 16 July 2005 at 2220 (BST), in near darkness, two powerboats collided near Castle Point, St Mawes, resulting in the death of one of the helmsmen.

Safety Issues

  • the speed of the vessels
  • the lack of navigation lights
  • the training and experience of the helmsmen
  • that both helmsmen were navigating while under the influence of alcohol


As a result of our recent investigation into the high speed grounding of the powerboat Sea Snake, which resulted in the loss of three lives, and this investigation, a recommendation has been made to the Department for Transport (DfT) concerning the 3 introduction of an alcohol limit for leisure users. The DfT is also recommended to improve the harbour bye-law approval process. The local harbour authorities have been recommended to review the standard of leisure boat activities in their area.
