The shape of the shoreline delays and enhances the tidal effect. Canada's Bay Of Fundy funnels incomming tides causing them to reach enormous height. What are vast mudflats at low tide will float large ocean going ships at high tide. As the water flows into Minas basin it is funnelled some more creating the world's highest tide at Burntcoat Head.
The Bay Of Fundy is on the list to be named one of the world's seven natural wonders.
