I'd suggest the Exploring series cruising guides
by Douglass for anchorage information, especially for north of Cape Caution. There's one for SE Alaska, one for the North Coast of BC, and one for the South Coast of BC. And another for the west coast
of Vancouver Island, bit I haven't used that one.
For BC tides and especially currents (there are several rapids you must plan for) get a copy of the 2014 Ports
and Passes book. Much less confusing than the Canadian government
tidal current books
. For SE Alaska currents, you can pull the data from NOAA's web site - I usually print the current charts
for the handful of places where it's critical to know the timing.
We've traveled the Inside Passage, mostly at 6 knots, in a small power cruiser the last 20 summers. Sitka is one of our favorite stops, but there are so many more favorite areas I'd be happy to discuss. Hardly know where to begin. How much time do you have? Are you heading only up to Sitka and back, or might you wander around more, and possibly further north? Interested in Glacier Bay or the beautiful Tracy Arm and its glaciers?
Over the years we built up lists of anchorages
we've either used successfully or think are appropriate for us. We find them handy for planning the next day's destination
, including potential bailout spots along the way. I'd email
if you send me your address.
