For a pleasure boat electrical system what you should have is a current operated relay, either mechanical or electronic, that switches off the alternator field when the current reaches some level, probably five to ten amps. That will be one choice. Better yet, switch it off when the voltage reaches about 14.2 volts, OR ten amps, switch it back on when the voltage drops to 13 .2bvolts.
