Yes. A starting battery may deliver hundreds of amps over a short period of time coming off the outer surface of multiple plates. But a deep-cycle bat- tery, to keep your electronics running for a long period of time, will have thicker plates to continue to power your circuits over a longer period of time than the starting battery. Battery expert Don Ross reports, “A deep-cycle battery may be used for engine starting, but a starting battery should not be used for regular continuous deep-cycle applications.” So, go with a heavy deep-cycle battery, and you will be set for both starting and running your electronics for the regatta. As you are doing so, keep an eye on the volt meter, and when you get down to 12.2 volts DC, fire up the engine for a fast recharge.
