When it comes to promoting my books, my wife says I’m much too shy. She tells friends that I won’t even ask a book...
Fast, reliable broadband connectivity is often taken for granted ashore. But once youre out on the water, the digital domain can go downhill fast and access to high-speed, cost-effective digital communications begins to waver. Cellular towers and Wi-Fi hotspots are the inshore sailors next best friend, but since Wi-Fi signals are line-of-sight, the range is limited. How these two important links to Web-based communications-cellular and Wi-Fi- work and what you can expect from the technology in the marine sphere is part of our ongoing electronics update.
Oscillating models fail early in long-term testing.
Our years of sailing in New England and the Caribbean, with their stable, predictable weather patterns, left us ill-prepared to deal with the vagaries...
Practical Sailor looked at three Wi-Fi antennas suggested by readers: the Bad Boy Xtreme from Bitstorm, Rogue Waves Wave Wi-Fi from GeoSat Solutions, and The Wirie, developed by cruising couple Mark Kilty and Liesbet Collaert. All three are marketed specifically to boaters, and they represent the two principal types of devices that users will find: USB-type units that plug into computer or laptop USB ports and Power over Ethernet (PoE) bridges that network via your computers Ethernet port to provide a pathway to the Internet.
Its dusk on an overcast, gusty day, and raw data is pouring into your wind display from the masthead, GPS, and the knotlog. Can you clearly see the information on the display, and more importantly, is it meaningful? Can your gloved fingers push the buttons? Can you easily change the way wind data is collected, processed, and displayed so that it best reflects the conditions? These are among the things testers examined for this report, Part 2 of our wind-sensor evaluation, which focused on the display and user interface. In Part 1 (PS, March 2014) we focused on accuracy and durability of the anemometer and vane sensors that feed into the displays.
Mast antennas, like all electrical components, are particularly vulnerable to water intrusion at connectors. In the extreme, corrosion at unions or terminals can damage a transmitter.
Of five packages tested, we also like Coretex Weatherfax 2000, but had problems running the much more expensive Weatherstation 2000 HW and PC HF Facsimile 8.0
Version 1.0.0 of Signal K, the Open Marine Data Standard has now been released, giving developers a stable platform to test and develop new open-source hardware and software for sailors.
