Often went out in s/m's from Faslane to take part in work up or "Perisher" training to practice s/m in SF work. Would sometimes arrive at night in Rothsay in a couple of canoes, buy about 26 lots of fish and chips from Zavaroni's fish and chip bar, put them in a dustbin liner then set off in the dark to rejoin the s/m. Locals must have thought we were hungry as the s/m was submerged...but we gave them to the s/m crew in return for borrowing a bunk instead of sleeping in the "fore ends". Too many stories to recount here. Happy days and nights.
