Quite right. We called it iron bark, same stuff and yes it will sink like a stone. Actually a very pretty wood, dark with lots of contrasting grain, but super tough. Cannot drive a nail into it either.

My dad used to occasionally work on a local tug that had been converted from one of those same sweeper hulls, company was Alaska Outport, don't remember the name of the boat though, wait!! Just remembered. It was the Klehowa.

I was visiting my grandparents place in Fremont many years ago, family get together. I happened to look out towards the Fremont Bridge when lo and behold, the Calypso had just passed! Only time I ever saw it, outside of TV and books.
