Chartplotter battery monitoring

Battery monitoring on our vessels is an obsession comparable to keeping an eye on the wind indicator and the sail telltales. With all of us skippers fussing over slight changes in battery charge several times a day while on passage, we would expect a horde of manufacturers pandering to us with battery monitoring systems compatible with our chartplotters, right? Nope! Of all the marine and recreational battery monitoring systems on the market, only one offers compatibility with our chartplotters: the Victron Cerbo GX, “a hub for all energy on board.” To be sure, other monitoring systems have jumped straight ahead…

Stand-alone AIS units

Stand-alone AIS units

A stand-alone AIS transceiver is a must for both coastal and offshore sailing craft, especially around large harbors with lots of ship traffic and sometimes dense fog. AIS-equipped VHF radios are generally limited to receiving AIS transmissions and displaying them either on a small screen or a separate chartplotter.  To alert another vessel, the operator can either call by VHF radio or activate the DSC (digital select calling) function, which transmits the vessel’s name and position with the vessel’s Maritime Mobile Service Identities code. The advantage of a self-contained AIS transceiver is obvious: Every AIS-equipped vessel in your area is…

With all the advertising and dockside chatter surrounding satellite cell phones and the cost of monthly plans, it is comforting to know there are still active marine SSB nets for cruisers all around the globe. As a matter of fact, SSB transceivers, along with ham radios, are still the norm among offshore cruisers.  However, because we offshore sailing folk do not (but should) comprise the huge customer base it takes to shape economies of scale, we are relegated to limited sources for some of our specialized electronics, particularly single-sideband AM radios. Which explains why three manufacturers — ICOM, Furuno and…
