The Eyes Have ItLearning to see the world around us should be the heart and soul of navigationBy Charles J. DoaneQuiz any nautical curmudgeon on the subject of proper wayfinding these days and you’ll soon find yourself reefed down in a gale of conventional wisdom about the importance of paper charts, compass bearings, dead reckoning, and the divine art of

Tacktick’s new solar-powered waterproof Race Master System is packed with useful features, including an electronic compass, a speed log, and a depthsounder, and can be wirelessly networked with other Tacktick instruments to display wind speed, wind direction, windshift averaging, and mean-wind-direction data. In addition, it can connect to your boat’s NMEA interface to display GPS data. The kit’s

Keep Control

by Sail Staff, Posted June 16, 2007
Wireless is all the rage on boats these days, as exemplified by the advent of handheld multifunction controllers. Simrad’s RemoteCommander is a prime example. Not only does it let you control your NMEA 2000–compatible autopilot, chartplotter, and other instruments from anywhere on the boat via Bluetooth, it is also a VHF handset. Simrad USA, 425-778-8821,

Energy Conscious

Few things are as discouraging as coming on board your boat, only to find a dead battery. Microlog has created two new affordable battery-monitoring systems, the DMM-3-BR (for two batteries) and DMM-4-BR (for three batteries). The monitors protect your batteries against deep discharges, provide accurate measurements of two and three-battery banks, and measure system charge, discharge, and net

Man Overboard

These are the two words that no skipper wants to hear, but with the new MOBi-lert 720i system she will quickly know if someone unexpectedly exits stage left (or starboard). Each crewmember carries a small MOBi-ilert PTX unit, which sends a constant signal to the system’s monitoring unit. If one of the PTX units is submerged, the transmission is broken and an onboard alarm is automatically

Sailors rely on batteries to power any number of gizmos, but in the case of disposable batteries, this reliance comes at a hefty cost to the consumer and to the environment. More Power 2U claims its new Battery Xtender safely and effectively recharges disposable alkaline, nickel metal hydride, nickel cadmium, zinc carbon, titanium, and rechargeable alkaline manganese batteries without

Constant Watchman

by Sail Staff, Posted February 16, 2007
Clearly seeing objects at night and keeping a watchful eye on your yacht are objectives that any owner seeks, especially if these can be accomplished from anywhere. Night Vision Technologies’s 6000 series multiple-sensor vision system boasts a thermal imager, a high-resolution 312X zoom color camera, and an ultra-low-lux camera for crisp diurnal or nocturnal viewing. The unit also features a

Shakespeare ART-3

by Sail Staff, Posted November 10, 2006
That in-the-red VSWR, reading on the ART-3 tester confirmed my suspicion that while the old VHF antenna attached looks okay, it must be fried internally. VSWR stands for “voltage standing wave ratio,” but Shakespeare reasonably calls it “antenna efficiency.” The ART-3 can also test transmission wattage (only 17 with this particular antenna, but a full 25 with a decent one) and can generate a tone

Port Networks MWB

by Sail Staff, Posted September 9, 2006
Port Networks’s approach to maximized marine WiFi is to minimize coaxial loss by packing a high-powered radio and 5.5-dB antenna into a waterproof box for deployment on deck whenever you’re docked or moored. Both power and signal run through a no-loss 25-foot Ethernet cable. While the $349 MWB-200 will usually find the best available WiFi signal automatically, complete control software is
