Just been having a read through the BBC news site and came across...

"A Royal Navy petty officer caused the death of a junior officer by letting
him dive on a full stomach in breach of safety rules, a court has heard. "

Until recently, I was the satisfied owner of a Northern Diver weight
harness. Until, that is, I foolishly volunteered to be the casualty in
a rescue scenario.
The rescuers decided to undo every single clip they could find on me

Does anyone know where this wreck is near Dale  in Pembrokeshire?  I've
never heard of 'HMS Caroline' despite having dived around the area for
years...

We are currently busy with a university project to look into the
possibility of improveing the current spear fishing buoys...
