If my distribution panel on my boat is wired 240 v 60 amps max and there are many 120 v 15 a circuits, if one side of the 120 v panel starts to draw more than 30 a, will the breaker compensate by adding amps from the low usage side of the panel ? to a max of 60 amps
Electrical – On a true 60 amp 240 volt circuit will each side of the breaker carry more than 30 amps if required

No, that's not at all how it works.
This feeder will provide 60A @ 240V. That is 60A on each leg of the panel, NOT 30A on each.
The 60A is available, you use what you need up to roughly 60A, again, on each leg.
A residential panel will be hard pressed to be fully balanced, or greatly imbalanced, due to the transient nature of usage.
