Marine Technology

If you love watching television, you can still enjoy this pastime after you have sailed off for open water.

An important function of a chartplotter aboard today’s cruising yacht is its sonar bottom-scanning system.

A flash of white light broke the darkness as Saltaire motor-bashed into a light gale late one night in the Bay of Panama.

Since emergency position indicating radio beacons (EPIRBs) made their debut as an aid for tracking crashed U.S. military aircraft in the 1950s, this technology has steadily evolved into more compact, highly accurate, life-saving devices priced well within the budget of any serious cruising sailor.

The race to combine a wide assortment of technology in small, hand-held wearable devices has recently yielded a new animal: the GPS-capable smartwatch.

AIS, GPS and a VHF radio with DSC are all must-haves on the modern cruising yacht. Now imagine having all of these features in one device.

Traditional depth sounders seem to get short shrift in dockside conversation these days, owing of course to the proliferation of multifunction chartplotters and the array of information they offer to cruisers with fingertip ease.

The proliferation of electronic navigation, communication, power and security systems on modern yachts demands a dependable means of diagnosing these systems when they fail or fall short in performance.

Most cruising sailors demand state-of-the-art electronic navigation systems for their vessels, but many skippers also like to preserve a traditional look in the displays they install in the cockpit.

As much as we love the water, the very thing we fear most with our personal electronics is an unintended dive into the briny deep.

Many cruisers are seeing their legacy permanent-mount GPS units gradually fade, wither and succumb to an ignominious death.

Long jaunts ashore drain personal electronics of battery power, potentially leaving us without the use of a cellphone, portable GPS, hand-held VHF radio and other personal electronics.
