Portable Marine Refrigeration Test
One of the advantages of a compressor-driven portable refrigerator is that it can also serve as a freezer. And compared to thermo-electric coolers, they require fewer amps to do the job. Cruising boats need to be energy efficient, so amp consumption with a 12-volt power supply was one of the key factors Practical Sailor looked at in this test. As in any marine refrigeration test, insulation is a key factor in efficiency, so our comparison also tried to single out the best insulated units. Ultimately, the linear compressor system used in the Engel and Norcold refrigerator/freezers proved to be more efficient.
Marine refrigeration: Thermoelectric Cooler Test
The main drawback of thermoelectric coolers is power usage. This will likely be an issue during extended use or for boats with small battery banks and anemic charging systems. The 106-130 amp load, over a 24-hour period, is about twice as much demand as a built-in evaporative sytem and about three times the demand of the most efficient-and most expensive-installed systems. Also, thermoelectric units are limited in their ability to cool internal temperatures, usually to a maximum of about 40 degrees below the ambient temperature.

Rhumb Lines — Getting a Fix on Reality
It was mid-July 1990 on the Caicos Banks, a stretch of shallow, gin-clear water extending for about 70 miles east to west in the Turks and Caicos Islands. Along with a dozen other cruisers whod chosen to thumb our noses at hurricane season (ah, those were simpler times), we were pausing in Providenciales before heading south. …
