The Marine Technology Hub
Littelfuse — a large Chicago-based manufacturer of industrial technology — is acquiring Carling Technologies, and that makes me a bit nervous about the future of Carling’s marine brands. Will Octoplex, MPower, and especially all the (great) Maretron electronics on my boat continue to be developed and supported even though Littelfuse currently has only a minor marine market presence?
The 2021 Fort Lauderdale International Boat Show was the first major consumer show I’ve attended in nearly two years. Although the 2020 show took place in October of last year, I wasn’t there. I heard reports from colleagues of a dramatically smaller show with empty booths, smaller crowds, and very different energy. This year, the show was a little smaller than the last one I attended in 2019, but definitely felt like FLIBS. Although it was different, I think many of the differences result from the scarcity of available boats and components.
When I got serious about sailing and seamanship fifty years ago, I read all sorts of offshore cruising and racing accounts, particularly interested in the problems that came up and the solutions found. It seemed valuable to learn that, say, a well-found 46-foot ketch could pitchpole stern-over-bow in certain situations and how the crew survived. But eventually I realized that there was a whole niche of especially extreme ocean voyaging that was almost never discussed, except maybe quietly in remote harbors or jail cells…
Fusion’s new Apollo amps address several common difficulties with installing and tuning boat stereos. They offer easy installation and tuning from a smartphone application. On paper, there’s a series of improvements, but it wasn’t until I installed one that I appreciated their biggest improvement. It’s rare to find an amp in an easily accessible location. Fusion understands this and made an amplifier designed not to be visited once it’s installed. But, how do they do on the water? I’ve been evaluating the six-channel model on Panbo(at), so read on for more about the installation and tuning process and most importantly, how it sounds.
Last spring Balmar rather quietly introduced the new MC-618 regulator, but I think it’s a pretty big deal and have been pleased to see how well it integrates with their SG200 battery monitoring system. While the scene above is only a bench test, I expect the 618 to work fine on Gizmo because it’s essentially an update of the venerable MC-614 technology that’s been managing the boat’s main alternator since 2011. But configuring, fine tuning, or troubleshooting the new regulator will be a whole lot easier, plus I’ll be able to see how the charging system is performing in real time…
NMEA 2000 networks are pretty reliable but when there’s trouble it is often unclear where to start. Digital Yacht and Actisense have both brought out new products to help ensure the health of a network and better understand its operation. But, even if you don’t have any specialized tools onboard, you can still do some basic but effective troubleshooting of the health of your network. Let’s explore Digital Yacht’s NAVDoctor, Actisense’s A2K-TER-U smart NMEA 2000 terminator, and the troubleshooting you can do with an NMEA 2000 breakout cable and a multimeter.
Allan Seymour wants to see the current Dew Point and outside Air Temperatures at the helm of Sally W because fog is often about to shut in when the two temps become similar. And there are at least three marine sensors that claim to deliver dew point over NMEA 2000, two of which Allan owns. But actually getting the value to show on his instrument display turned out to be quite a challenge. I helped with the troubleshooting, and came to better appreciate the value of dew point in the process…
The Victron Remote Management (VRM) portal and their Venus OS monitoring software deliver best-in-class access to information about your boat (, RV, or fixed solar) electrical sytem. But, running one of these systems has typically required Victron hardware which starts around $300. Victron has a long history of embracing the open-source community and they’ve continued that effort by supporting Venus OS on a Raspberry Pi. But, many people hear Raspberry Pi and either think dessert or that it’s over their heads and too complex. This guide walks you through the steps required to get Venus OS up and running on a Pi and sending data about your electrical system to VRM.
Class B AIS transceivers only became legal in the USA about 13 years ago, but they’ve certainly become valued equipment on many mid-size and larger recreational vessels. The Class B regulations have also improved — when the higher-power, faster-talking SOTDMA transmission protocol became a choice — and many manufacturers added useful features beyond what’s required by the AIS regulations. The AMEC WideLink B600W that I recently installed on Gizmo Junior pretty well illustrates the state of Class B these days, and also includes a rare data multiplexing ability that can improve PC or tablet navigation…
Despite a rocky start, Ben Ellison wrote enthusiastically about Across Ocean Systems (AOS), their NMEA 2000 pressure sensors, and their clever WiFi configuration. AOS has followed their pressure sensors with a suite of electrical...
