I don't think it's a tanner crab. I see them around a fair bit, but never in the Strait of Juan de Fuca. The red crab does have a similar build to the tanner crab though. Maybe they're in the same genus or family or something.It looks like a Tanner Crab but the ones I have seen are always brown. My Whelks To Whales says they are pink after a molt so maybe that's it. Nice colors.
