Watch out for the sandbar (extends 3-4mi out from the shore) just south of
Vancouver off Steveston/mouth of the Frasier river. If it's not crystal
clear, it's pretty much impossible to sight landmarks/markers to judge
whether you're far enough offshore or not due to the distances involved and
the rather flat land surrounding. (i.e. bring a GPS and you'll be fine).
I've eyeball navigated the trip from B'ham south several times without any
trouble (using charts, of course).

That's Roberts Bank, and it's dangerous for the reasons you cited. However
there is one advantage in that the shoaling is gradual. Keeping a close eye on
depth is a great defense. You can hear about the weather and sea state of that
area by listening for "Sandheads" in the Can broadcast.
