Impact of Tides on Loading/Unloading, PEI to NS

It is the one on the ferry at Dawson City you need to worry about - no adjustment there.

(but even if the ramps do adjust, unless they design it right - which they often don't because they must get a certain amount of pleasure thinking about the damage they cause - there can be certain extremes of tides where the angles are such that some rigs might scrape a little.)
