I’ve snorkelled from a C50 in
Greece. All the fittings on these
cheap yachts a flimsy and poorly made. This includes the boarding ladder on the fold-down transom platform, which bends under the platform under the weight of this 100kg sailor, making it really hard to get out of the
water in Speedos, let alone dive kit.
Just saying.
I would have thought the most efficient way to blow up a pipe would be from within, using a
maintenance drone. Or maybe I’ve seen too much James Bond.
I do hope the truth comes out eventually. Fascinating!
Oh one final thing - could residual gas in the pipe really add to the blast? Wouldn’t it need mixing with oxygen?
I am very good with boats, but know nothing about explosives, and not much about deep
diving.
