Well in the boats where an engine is dedicated to charging duty it (that engine) would charge at whatever rate it was set for.

The speed of the other engine would be irrelevant.

I do know that diesel engine generators are controlled to run at a constant speed and adjust throttle according to load to maintain that speed. However that is because they have to produce a consistant 60 cycles per second regardless of load. In order to charge batteries the alternating current would have to be converted to direct current so that cycles per second would not be critical and basically the faster you can spin the generator the more 'juice' you can get out of it.
