Much of Earths tides are caused by Luna. Assiniboia, Regina's primary is tens of thousands of times heavier than Luna is. Oh, sure Regina is about 38.3 times farther away than Luna is (55 diameters of a size 170 or so world is about 9.35 million miles, vs about 0.242 million miles between Earth and Luna) but that will only reduce the tides about 1,500 fold. (Inverse square law)
Since Assiniboia, as a large gas giant should have a mass over 1,000 times that of earth, while the moon has a mass of about 1/81st of earth. Therefore the "lunar" tides on Regina should be about 62.5 times higher than Earths lunar tides.
Since many parts of earth have tides of about six feet (30 feet here in Anchorage, but we're in a fjord) and earths tides are about one third solar and two thirds lunar than Luna must cause about four feet of tides on earth. Multiplying that by 62.5+ we get 250 feet of tides in average areas. Converting back to metric, as all Traveller measurements should be, we see that Regina should have tides of about 80 meters.Why would anyone ever live by the sea?
Also, what about erosion? Why haven't the continents been worn down into the sea by now? How new would they have to be to be as big as they are?
