I should have mentioned that my The Capn nav software includes Tides and
Currents, but the graphic representations on the charts is very limited..

I prefer the Current Atlas approach since it shows a series of arrows in
most all passes and regions where accelerated currents might be experienced.
I consider it "good sport" take advantage of this and any back eddies when
the main current is against me.

One of the problems I expect to encounter are determining the current set in
some of the Inside Passages, since this might be counter to what would be
expected.

The marine charts do show feathers with the direction of
current flow all up on the BC Coast. In general in Southern
Georgia Strait they flood north, meeting the south coming
flood from the north end of Vancouver Island around Savary
Island.

Further north the flood current flows inward from the sea in
general.
