Our wreck has been checked over by the US Navy, experts from the US Parks Dept (who deal with US historical wrecks) and many other experts and we have been given an 85% probability that it is the Bonne Homme Richard. No other wreck sank in the area during that time period
This is not good enough for him and he has been funding an annual search since around 2003.
His organisation (NUMA) is superb at finding wrecks (he found the Marie Celeste off Haiti for example) and I think he always wanted this to be his final and most superb challenge.
His son Dirk has taken over the reins but I don't know if he will continue.
Sorry, but I am a total nerd when it comes to marine archaeology (and seaweed)
