Conventional wisdom says yes, starboard side northbound.
The reality is, however, that there are so many islands and inlets and this arm and that fijord that it really dosen't matter. The views are spectacular from either side. Don't go by the map in the brochure--check out a real navigational map of the area--you'll see what I mean.
As usual, f-mattox is right on the mark. Don't worry about which side of the ship. I recently had a client not happy with me because she chose the side that appeared to her to be the land side and I failed to tell her on the other side of the ship passengers were spotting dolphins and whales from their balconies regularly. Guess I should have known that. Guess I'll have to study those migration paterns before next season so I don't miss something I should have known.
Being that you are in the inside passage, either side works just fine. We never spent much time in our room anyway. You will see scenery on both sides.
