If I was to buy one set of cruising guides, I would go with the "Fine Edge" publications by Don Douglas: Exploring S E Alaska,, Exploring the North Coast of British Columbia, and Exploring the South Coast of British Columbia. The books are about 10 years old--maybe older, but they are excellent, with minimal errors. You may have to find used books. Fine Edge also publishes Waggoner Guide. Don Douglas did a single version book from the San Juans to Glacier Bay in 1995--now out of print ($80 used). There were errors, which were corrected in the newer sectional editions but if you only want one book--that is probably what I would choose.
For general overall planning, we had a tourist type of map which showed the entire passage on one or two pages, and thru the years, plotted our different routes in Sharpie marker. There may be a cheaper one, but ours was similar to
National Geographic map. Fine Edge makes one which is I believe the one we used.
Also National Audubon Society Field Guide to the Pacific Northwest, would be a minimal nature guide. We also use Sibley's field guide to birds. There are a few other more specific guides.
Knowing the tides and currents are essential--but you can travel 3 to 4 times faster, and thus hit many passes in one day--than in a sailboat--which most of our trips to AK were in.
Link has some very good comments and referrals. We used current books and tables,
On our first trip to AK we were lucky to get a set of complete charts (over 200) from a friend who is a tugboat skipper. These were fully annotated, and only a year old. But where do you put over 200 charts on a Tom Cat (OK--you could load up under one of the hulls under the forward berth... With GPS, Active Captain, and a good tide/current program you should be fine... On the C Dory we had an Evergreen chart atlas up to N. BC. I don't recall, which older atlas we had for AK.
Thru the years I read a number of older books: Such as John Muir's Travels in Alaska--First trip to Glacier Bay in 1879! Captain Cooks, 3 voyages, 1768 to 1779. "The curve of time" is a classic must read. There were many others, most I picked up at used book stores. Reading in one of the books, we found a location with several log dugout canoes with human skeletons in them--I am sure well over 100 years old, and not disturbed. We took photos, and were extremely careful to not touch or move anything in this site.
Side trips, I think are "most do"--Princess Louisa Inlet, Buchart Gardens, by water, spend at least a day (and night) there. Dinghy to their dock, Ford's Terror. Ocean Falls.
Pack Creek for Grizley Bears, and if possible Queen Charlotte Islands--if just one part, the South. Of course it is impossible to see all in one trip. We made four, six months trips in the Cal 46, and one, one month trip in the C Dory 25.
Real all of the information posted by other C brats, especially Jay and Jolee (Hunkydory C D 22), and Brent and Dixie (Discovery TC 255). There are a number of C Brats in SE, and along the Inside passage--reach out to them for local knowledge. (hint--go to our C Dorys and Membership list and find out where the owners are in AK)
The Inside Passage is my favorite cruising ground of the entire World...
