Cabin Comfort

In this LED cabin light test, Practical Sailor looks at 17 light bulbs from seven manufacturers. The LEDs were tested to see which was the most worthy replacement for a 20-watt xenon bulb in a bulkhead-mounted reading light. Testers measure LED beam angles and intensity, LED power consumption, LED color temperature, LED radio frequency interference, and LED reading and cabin illumination. The LED lights tested include: Alpenglow TR LED complete brass fixture; three lights from Cruising Solutions; three lights from Doctor LED; four from Imtra; two from Opto Technology, two from Daniel R. Smith & Associates (DRSA) manufactured by Mast Products; two of Scad Technologies (Sailors Solutions) Sensibulbs; and one LED light from West Marine.

I have an air-conditioning unit with more than 14,000 BTUs. Here in Florida, with a 38-foot boat, that just doesn’t hack it. The unit’s been checked for efficiency by a technician. My prior boat (also 38 feet) had two units totaling over 20,000 BTUs. Those were effective, but that output is enough to cool a small store ashore. How are boat A/C BTUs determined? I suspect the temperature of coolant water is a major factor. Also, what is the effect when coolant water is suppressed by a clogged filter? Are they built to automatically shut down the compressor?

With bug season upon us, a new product we unearthed during our medical kit test (see page 32) seemed worthy of a closer look. Natrapel 8 Hour, from Tender Corp. (parent company of Adventure Medical Kits), promises DEET-free protection from mosquitoes, ticks, no-see-ums, biting flies, and other nasties. While DEET, an EPA-registered pesticide, is the most common active ingredient in bug sprays, Natrapel uses Picaridin, a chemical that has been used in Europe for 20 years and made its way into the U.S. this decade. The Centers for Disease Control recommends both DEET and Natrapel as effective insect repellents. Both also are registered with the U.S. Environmental Protection Agency, which includes oil of lemon eucalyptus and oil of citronella on its list of active ingredients for repelling insects.
