I have been concerned about the effect of tidal forces on my earth-like moon (0.7 earth masses and 0.88 earth radii), specifically given that because of the primary's mass (3 Jupiters, 1.04 Jupiter radii, at a distance of 1003917 kms) there would be hundreds of meters high or even kilometrical waves assuming earth-like oceans. Recently however I learned that there are several factors that can affect the tides besides the masses and gravity involved, with the main one being the shape and topology of the oceans.
My main questions are: how much does the shape of an ocean on an earth-like planet actually affect the effective height/strenght of the tides? Could it make the tides more manageable with increases of tens of meters rather than hundreds?
And to evaluate an idea that I had already, what if the oceans of my world weren't as contingous as earth's? What if they resembled more interconnected seas, resembling more the topography of south-australia, the carribeans or the Melanesia? They'd also be shallower on average (about 2 kms), would that help?
As illustrated here:
*Note that the moon isn't properly tidally locked, it's in a 5/2 spin orbit resonance.
