Brian, yes I often would get quite overly imaginative as to what would happen if we had a head on to me on the forecastle when in thick fog. Must say I had visions of the Andrea Doria & that passenger that wound up on the other ship in someone's cabin. BSL were certainly not into modern gizmos, how many even had iron mike? Very few even in the mid to late 60's. I remember the beaver boats well Beaver Ash anyway when I went on the wheel first time going down the Thames in fog. There was no wheel just two I think little joy sticks & when you were given a course change you had to remember to ensure that you hit the say port joy stick to stop the rudder or she would go hard over. If told 20 degrees of starboard rudder you had to watch the rudder indicator & ensure you took helm off say at 15 let her coast to 20. I feel she was very agile too from memory? A few times that first watch, 12-4 my personal favourite I did forget causing one or two caustic comments. I reckon we should have been shown-introduced to that system before we sailed or at least the watch & it was night as I recall. Still a beautiful little ship.
