A photograph appears to show a large door of the Bayesian was closed minutes before the superyacht sank - contrary to claims it may have been left open.Seven people, including British tech magnate Mike Lynch and his 18-year-old daughter Hannah, died when the 56m superyacht sank in a storm off the coast of Sicily in the early hours of August 19.Prosecutors are investigating three people on possible manslaughter and shipwreck charges, after the boat sank despite another yacht that was moored nearby managing to weather the storm.It has been alleged that crew on board Bayesian left a large door towards the rear of the craft’s port side open, meaning waves were able to wash in, contributing to it sinking quickly.But a photo taken by a passenger on another nearby yacht - the Sir Robert Baden Powell - just 14 minutes before the sinking appears to show the door was shut, The Times reports.
