True, true. But imagine those tides in a slightly larger bay: 52km wide at the entrance (compared with ~14km for Severn), mostly linear (48km near its neck, compared with ~2km) and over 155km long.
The amount of water that comes in an out twice a day is, well, nuts. Yes, that's the technical term.
(Summer ferry crossings between Digby Neck and Saint John are 2.5 hours, 3.0 hours in the winter (slower due to rougher water), but I do know people who took ~12 one February: the water was so rough they hugged as close to the shores of NB and NS as they dared, just to make things a little calmer. There have also been cases of transport trailers falling over in the hold. Yes, they were lashed down.)
(I once spent a terrible several hours sprawled on a lounge chair staring out the window on the opposite side of the boat: For seven seconds I could see nothing but sea, the ship swung, and for seven more, nothing but sky. Repeat. Ad nauseam. The swings took about a second. When I finally did get up to head to the heads to unload that nausea, let's just say planning was involved in every step.)
(Another trip, I also spent an uncomfortable few minutes on the observation deck bow-ward of that lounge, because young and dumb: It was fall, I was heading back to Uni, it was cold (duh), I was wearing a hoodie and shorts, and I'd stepped out for fresh air. Got talking to American tourists in long slacks and sweaters. Felt expansive and loquacious, kept them out there as long as I could. They finally excused themselves on account of the cold, very polite, and I turned to and leaned upon the bow rail until I felt enough time had gone by that I could return to the lounge. Man, it was cold. Ah, youth. :->)
