Non-Scientist here. Assume that you had a two body system (planet-moon, double-planet) where one of the bodies was very close to tidally locked. Say they are closely co-orbiting at 6 to ten diameters in a relatively quick 20 to 50 hour orbit. One of the planets is close to being tidally locked but not quite there. Say the "month" is 1/10th to 1/25th longer than the day. The companion moon/planet would be seen from the sky for extended periods on one hemisphere (maybe weeks), then disappears for quite some time. Question 1: Would this affect the tides in any meaningful way if there was a slow motion "high" or "low" tide? Would they be weaker in any way, meaning not rise as high? Or would they just rise and stay there for a longer period? As the moon/double-planet would be very close, I would assume they would be very high tides in the perhaps hundreds of meters. Does speed of planetary rotation effect the tides in any way other than how high they remain at their peak? Question 2: Once the planet becomes tidally locked, is there a permanent "High Tide" excluding any solar tides, or are there other factors in play? With the moon's/other planet's gravity create a permanent "bulge" pulling the tidally locked face of the planet to the other body? I have this idea for a double-planet system, one of which is tidally locked but the other is close to being tidally locked. I'm just not sure if there is something I'm missing. Thanks.
