Hello Phil: Catalina is shipping new 36mkII models with a factory-installed 12-Volt refrigerator. Is this one or your models? If so, can you tell me what to expect as an average 12-volt current drain, and the typical duty-cycle over a 24-hour period? A typical number for amp-hours consumed over 24 hours, or watt-hours consumed would also do the trick. I'm trying to work out a power budget for the boat. Thanks so much! Al
