Two years ago, I replaced my incandescent stern light with a waterproof, sealed LED unit from OGM (www.miseagroup.com). This winter, while the boat was on the hard, I noticed that the seal had failed and drops of water fogged the lens. Although the LED continued to work, I was concerned that the moisture would reduce the visibility, or that the light would fail when I needed it most.
One of the primary causes of ruin for many pairs of binoculars is that they have no home. Loose in the cockpit, or sharing a coaming locker with winch handles — their usual places — it's no wonder so many pairs die of drowning or having their prisms knocked out of alignment. It's all well and good advice to always keep binoculars in their carrying case snugly stowed in a safe place, but in practice they're in such frequent use that the advice is unrealistic. What is needed is a snug home which is both protected and accessible. A binocular box mounted just inside the companionway answers all requirements. It keeps the glasses both protected and easy to get at.
Take a glance around the marina: One in five Americans will develop skin cancer in their lifetime, one in three Caucasians. In past issues, Practical Sailor has delved into the risks of sun exposure and options for protection, including sunscreens (June 2007), sunglasses (July 2009), and hats (June 2008). For this report, we took a look at clothing designed to block the suns harmful ultraviolet (UV) rays. Fabrics create a physical UV barrier, a shield that is longer-lasting, more effective, and more reliable than sunscreens. Although all clothes offer some protection from UV, not all fabrics have adequate protection. Testers sought to determine whether a $50 shirt designed for sun protection is really a better choice than our stockpile of regatta T-shirts or a regular, dark-colored tightly woven shirt that can be bought at a thrift store. We tested the performance of a range of sailing-appropriate activewear from Coolibar and Columbia Sportswear.
Only a few sunglasses manufacturers featured in last summers test (July 2009) offer childrens sunglasses, and those shades are usually just scaled down versions of the adult kind. After experimenting with several different styles for kids ages 3-13, we found that the younger children, ages 7 and under, were a tough bunch to fit. Harder still were kids ages 3 and under. Uncomfortable ear pieces were a common complaint.
For those of us who spend nearly as much time under the water as on it, the Liquid Image 310 video mask sounded like a great addition to our diving kit-and a good fix for our gadget addiction-so we had to give it a try when we came across it at a spring boat show.
Sight is the mariners most important sense, and tools that enhance visual acuity can be worth their weight in gold. Leicas newest addition to its line of premium-priced, high-quality optics delivers brilliant viewing-and at $2,200 costs nearly its weight in gold-but for the sailor preferring an uncompromising pair of binoculars, the German-made Ultravid 7x42 HD is a navigators dream. Although they lack a compass, they do afford camera-lens quality resolution and their low-light gathering ability is truly astounding. The ergonomic two finger-focus adjuster, water-tight armored coating, and extendable eye cups round out their superior design.
Practical Sailor ran field tests and lab tests on dozens of polarized sunglasses ranging from cheap to high-end products, including those popular for watersports eyewear. Field tests included wearing the products for eyeball navigation in shoal waters and assessing glare, color brightness, sharpness, fit, peripheral vision, and any interference with reading LCD screens or charts. Sunglasses that did well in field tests, and a few that did poorly, were sent to Pacific University College of Optometry, where they were tested in the lab for lens warpage, prismatic effect, tint, and resolution. The test field included polarized glasses from Bolle, Costa Del Mar, Gill, Harken, Hobie, Kaenon, Maui Jim, Oakley, and Nike.
A pair of top-quality 7x50 marine binoculars can be pretty pricey, but its an essential piece of gear on a cruising boat. Good binoculars offer superior optics, enhanced durability, and a long warranty. This binocular test update compares Steiners latest premium marine optics offering, the Steiner Commander XP, with the Commander V from Steiner, and the Fujinon FMTRC-SX. The Fujinon binoculars were the favorite in Practical Sailors 2006 test.All three marine binoculars in this test are waterproof and have a compass, a focus adjustment for each eye with a range of 5 to 5, 7x magnification, 500-millimeter objective lenses, and a rangefinder.
A thermal-imaging camera installed on your boat can significantly enhance safety during nighttime operations by clearly letting you see what is ahead and around your boat, even on the darkest or foggiest of nights. Practical Sailors review of Flir Systems Inc.s Navigator II, a thermal-imaging camera that can be mounted on a mast, finds that this kind of camera can aid navigation, man overboard recovery, and security. The equipment comes with a lofty price tag but for some, it will be worth the investment.
We pitted the Nikon 14x40 Stabil-Eyes against the Fujinon TS 1040 Techno-Stabi binocular, which beat out four competitors-priced from $500 to $1,300 and with magnification factors ranging from 10x to 16x-for the top pick in December. This time, the two nearly identical binoculars carry the same 14x magnification rating but do vary a couple hundred dollars in price. Performance-wise, testers consider these two units to be equals. We found no advantage to the Nikon for its extra operating mode as it proved to be of little use on the water. We did find significant advantages for Fujinon in two areas: its superior carrying case and its lower price. However, for normal day-to-day use onboard, IS binoculars are no substitute for a quality 7x50 binocular with compass.

So, a couple of years back, you acquired a good old boat at a pretty good price-thanks to the market-but now youre wondering how many coats of bottom paint it has. And what kind? Youve put on a few coats of ablative antifouling since youve owned the boat. It has adhered well and has done its job. But each year, the bottom looks rougher and rougher-with big recesses where paint has flaked off. You sweated out some extra prep-work this season, and thought you had a nice, durable subsurface for painting, but each pass of the roller pulls up more paint. Whats going on here?
