Yep....all the males in my family, grandfather, great uncles, uncles and father all were fishermen born and bred....not a one of them could swim a stroke.......great uncle swore he had negative buoyancy.....said he could just walk around on the bottom until he ran out of air.... Only reason any of them had those old WWII gummint surplus cork life jackets aboard was the Coast Guard made 'em carry then on the vessel....stiff fine for violations....none were good at giving money away...
Some one from Away once asked the Ol' Man why he never learned to swim.....he looked at the fella and said "The idea is to acquire a proper boat and then stay in it" and he was serious.....
Regulations and requirements became much stricter a few years after that episode, new laws and such came in so that there was a DOT approved safety vest for every person on board, life rafts became mandatory many years later.. Yep a good seaworthy boat and enough sense to stay inside/aboard was the earliest form of lifesaving I grew up with. First real world memory for me concerning boats was heading down the channel in Jeddore harbour with the ole single lunger in the 30' Tancook breaking the silence, at one point along the way the reverberating echo off the shoreline made it sound like the engine was a twin. No underwater exhaust on those old rigs, straight out the side, hear one coming 2 miles away even on a windy day.
