Marine Parks forever publishes a nice guide to BC marine parks. Agree that the rather out-of-date Pacific Yachting/Wolferstan books are still of value for the historical aspects in the text. (There's one for the West Coast of Vancouver Island as well)
I think TD has pretty well covered the other (more or less current) editions. Keep in mind that the marina and aquaculture situations are always in a state of flux, and often recommended destinations may well turn out not to be as advertised.....
There are a couple of pure marina guides out there... "Docks and Destinations" is one of them. Again, though, be prepared for changes to what's listed.
