Well, only time will tell. As for rocket powered boats..talking out his ar@@. But if members look at some of the final posts by mayhemmers on that subject, they do not relate to information put forward by him in early posts. We seemed to be grabbing at information that either wasn't there or was mis-interpreted by us or poorly presented by him. Regardless if he was a Walter Mitty type or otherwise, I think the members could have handled themselves with a bit more decorum.
As for Portsmouth City Museums John Stedman, he probably knows an awful lot about Portsmouth, but little about Naval matters, that is handled by the National Museum of The Royal Navy, half a mile down the road. Not Portsmouth City Museum, which could talk Sir Arthur Conan Doyle and Isambard Kingdom Brunel till the cows come home.
We have encountered con merchants before, remember the HMS Astute model from a few years ago..I met him on a number of occasions, without a doubt delusional. However, in this case, much made sense, until the jet boat! Maybe he had received some sort of commercial interest in the Hood/Bismark story, and was running before he could walk with other projects that were coming to mind, as I say time will tell.
As far as being a friendly place, Mayhem is still much quieter than when I first joined. I don't know when the last time someone was banned for thirty days, or booted off permanently ( Mr Caswell

)..
Personally, I like to help out where I can with enquiries, however, like another fellow (ex) trader on here, the constant questions on the same subject regarding, radio controls, paint, filler and speed control set ups can tax the patience of a saint!
Still, keep smiling, it's only a hobby, if it wasn't, I would have been out by now for good behaviour! wishing peace and love to ALL our fellow mayhemers, I need burgers, good night
