There's so little perceptible pitch or roll in most sections of the Inside
Passage that I doubt your tripod would be necessary. And on our trip, the
very few times that there was much ship motion, we were in one of the
sections both open to the sea and out of sight of anything worth
photographing. And this was on a 600 passenger ship, only about half the
size (or less!) of most ships on the route.
