There was a tragic one in the 50s at Powell River.
The "paper boats" used to be assisted from anchor to the dock at the mill.
During one cold winter night of a fierce S Easter the small tug, Tee Shu (I think that was the spelling), was capsized against and under the large freighter well out from the mill, in Malaspina Strait.
I don't recall how many were aboard other than one of my classmates who went along with his dad, the skipper.
He clung to a hatch cover through the night and was found the next day (maybe later, I don't recall) alive on the beach at Harwood Island. Would have been 10 or 12 years old.
Never have been able to find anything online about it although I see there is a tug currently in Powell River named Tee Shu.
