Well put John. That's precisely why I posed the question "Any of you spent much time navigating a nuclear submarine around the Kyles of Lochalsh? Or navigating any kind of sea-going vessel anywhere?"

As usual, the self-elected Mudcat "Experts-on-Everything" have taken great delight in slagging off a group of courageous, skilled people who do difficult, dangerous things, of which they themselves have no experience whatsoever.

Incidentally, it's believed that the word 'expert' may derive from two others - 'ex' meaning 'has-been', and 'spurt' meaning 'a drip under pressure'.

Sounds about right to me. :-) :-)
