Its more like a not smart/manual regulator- you use a rheostat to force a higher charging rate, maybe lower the charging rate as the battery reaches full charge- i think it turns off when it is fully charged- i'm not sure of the details yet.
Not really thinking of going to a higher output alternator at this time- just bought the boat this spring and there is a long list of upgrades to be financed.
thanks
