================================================

We now return you to the Harry Krause political crap programming.

When I think of a shoal, I think of sand or gravel. Not something that would put a
gash in an icebreaker's hull.

Weird. Wonder if it might have scraped a metal protrusion on a pier.

I didn't see much sand in Alaska. The beaches seem to be volcanic
rock, rounded by the surf. It is that black stuff you see around
gardens and such in the lower 48. I saw a lot of the same rock in New
Zealand
They also have regular old granite looking stuff.

Ice Breakers is a part of the CG that I had absolutely zero interest
in but I still ended up in some pretty cold water in the North
Atlantic. Fortunately we also went south occasionally ;-)

My neighbors in the early 70's kids joined the CG. Ended up on icebreaker.
Said using steam hoses to melt ice was interesting. Not fun. Would end
up with huge amounts of ice on the rails.

We chipped a bit of ice in the North Atlantic. We were using chipping
hammers. It was mostly to clear the ladders and ordinance but there
was a little concern about being top heavy. That was mostly unfounded
from what the old timers said. We were running the heat pretty good so
most of the ship was clear but you did accumulate a lot of ice on
things like ladders that stand away from the hull and superstructure.
They cleared the "tubs" just to deal with ice that might fall on the
decks and kill someone walking under it. Usually one good whack from
above and the whole thing would fall.

I met a guy years ago who worked the King Crab boats. He said the last
trip he would ever go on, they had 18" of ice on 1" stainless rails. They
were listing 40 degrees, and dumped the crab pots. They never saw their
sister ship again. I guess 0 degree or less temps and very high winds are
deadly.
