Ice chests come in all shapes and sizes. And often times, sailors and fishermen will prefer keeping a large cooler aboard to installing a marine refrigeration system. So for this test, we narrowed the field to portable 65-quart coolers and a 70-quart cooler from Yeti, Engel, and Coleman. The three test products were the Engel ENG65, Yeti Tundra, and the Coleman Ultimate Extreme Marine. Testers compared the effectiveness of each cooler at keeping ice during a meltdown test: A six-pack of soda was covered with 16 pounds of ice and checked at 12-hour intervals. The top performer was the Engel, but testers deemed the Coleman a bargain as it was less than half the cost of the others.

No bigger than a pack of gum, Freezer Safe is a digital recording thermometer that collects temperature data and displays it graphically. The battery-operated (two AAA cells) unit can optimize boat refrigeration systems by storing high and low temps for 100 minutes, 100 hours, or 100 days (though the batteries might not last that long). The data lets you adjust thermostat settings in order to reduce power use. The thermometer can also track warm and cold spots and help you find the best trade-off between food longevity and temperature. Freezer Safe can warn you if food may have thawed and refrozen, helps reduce the risk of accidentally freezing refrigerated foods. For holding-plate refrigeration systems to operate efficiently, the temperature cutoff on the compressor must be carefully set. Freezer Safe can help identify the ideal eutectic point for this system.

Practical Sailor contributor Mike Slinn installed two heads, the Raritan PHII and the Jabsco Compact Marine manual head, on his Beneteau First 435 and tested them during the summer cruising season in British Columbia. Two other brands of marine toilet were considered but for various reasons (fit in the head, et.), they werent chosen. The test looks at how both heads performed during the all-too-short Canadian summer and whether or not an expensive marine head does better in a long-term, real life test of marine heads. Our previous tests have shown that if you are looking for long-term reliable service from your head, you have to pay for it. Is the Raritan, at twice the price of the Jabsco, worth the investment? We also looked at fighting head odor and how it can be controlled and eliminated by the use of proper hose and proper hose connections.

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.

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.

Zero Degrees is a bargain at $20; CIs Music Cooler delivers tunes to boot.

The Ultimate Extreme Marine from Coleman and the expensive Frigid Rigid hold ice longer than comparably sized portable coolers from Igloo, Rubbermaid and Icey-Tek.

Reverse-osmosis watermakers run from $3,000 to over $8,000, and though many are similar, close examination is required for the buyer who wants the right one for his or her onboard needs.
