  A date for a full inquest was not formally fixed, and a decision on whether the inquest would be heard in front of a jury was deferred.
  The coroner said he would want to hear expert evidence into what public safety measures would be practical and recommendable, including the possibility of having sections of the beach for swimming only.
  "The provision of safety for the vast numbers of people that go to Camber is now an extremely important matter, and I owe it to the community as a whole to investigate as far as I conceivably can do," Mr Craze said.
