Raymarine LightHouse R17 part 1: hands-on new weather viewer, WiFi & more

19 May

Written by Adam Hyde on May 19, 2016 for Panbo, The Marine Electronics Hub

Raymarine Lighthouse r17 AnnouncementIf you have a Raymarine a, c, e, eS or gS Series MFD, you just got an astonishing array of free new features thanks to the just announced and available LightHouse Release 17 software update. In fact, I got the chance to try an early version of R17 on my boat Journey and have so much to report that I’ll divide it over two entries. In part 1, we’ll look at R17’s new full-featured weather display capabilities, as well as some advanced chart and waypoint enhancements, plus the unique WiFi capabilities that Ray has introduced over recent LightHouse releases.…

Yacht Devices N2K display, RedPort & PredictWind, NMEA & ABYC, and ONWA radar

Yacht Devices NMEA2000 Text DisplayYacht Devices appeared suddenly on the marine electronics scene last summer when Ben discussed their new temperature and barometer sensors. Not resting on their laurels, they then launched a $189 voyage data recorder that similarly came with either DeviceNet or SeaTalkNG connectors to minimize additional drop and/or adapter cable expense. More recently they joined NMEA and have now launched a new NMEA 2000 (N2K) text display which seems to be the least expensive and least power thirsty N2K data display available…

Yacht Devices YDTD20 data typesAt $149 for the YDTD-20 text display, the major caveat is that it will need a dry location because it’s not waterproof.…

Weather and communications on the passage

7 Apr

PW screenshot

If you’re following along, you know we left Ascension Island a few day ago. Now, most of passages over time seem to top out around five days. We’ve had a few longer ones (especially in the Indian Ocean), but that’s pretty typical at the high end, and mostly they range closer to about three days.

This passage, from Ascension to Barbados, will take around three weeks. It’s about 3,000 nautical miles: slightly longer than our longest passage to date, from Puerto Vallarta, Mexico to Hiva Oa, French Polynesia, six years ago this month (time flies!).

Passage hindsight: sailing from Madagascar to South Africa

6 Nov

DSC_8054

Sailing from Madagascar to South Africa is technically challenging. The Mozambique Channel separating them is famously dangerous, in particular for the effect of gales blowing up from the Southern Ocean against the south-setting Agulhas current. For a reference point that may translate better to sailors in North America, I’m told it’s comparable to experiencing a northerly gale in the Gulf Stream. There’s the very real possibility of some unpleasant weather, and big seas (20 meters!), and grief.

Happily, Totem is now snug in a berth at the Zululand Yacht Club in Richards Bay, South Africa, and this crossing is in the rear view mirror.…

Keeping current: ocean current data for passages

15 Oct

DSC_6629
Ocean currents have been a significant factor for our Indian Ocean passages this year, and our upcoming passage to South Africa is no exception. On this morning’s SSB net, one boat after another chimed in about the strong foul current they’re experiencing off the Madagascar coast as they head towards South Africa. Most entered the Mozambique channel at a point off the western ‘bulge’ called Cap Saint Andre. It’s 220 miles east of the Mozambique coastline, making it shortest point between Madagascar and Africa. One of the first boats reporting by SSB described two to three knots of foul current overnight – another said they had to start motoring because the current had them sailing backwards!…

Yacht Devices NMEA 2000 temp & barometer sensors, some good ideas but…

22 Jul

Written by Ben Ellison on Jul 22, 2015 for Panbo, The Marine Electronics Hub

Yacht_Designs_NMEA_2000_thermometer_aPanbo.jpgOne of the most valuable improvements I’ve made on Gizmo is a Maretron TMP100 able to put six different temperature sensors on the boat’s NMEA 2000 network, particularly the one I’ve set to alarm me if the engine block gets even slightly hotter than normal. I wrote about the plan in 2013 and will detail how well it worked out soon. Closely monitoring certain temperatures can save a lot of hassle and money though one impediment is the need for either a Maretron DSM display or a USB Gateway to configure the setup.…

Weather watch in Maldives

9 May

DSC_9500

For the duration of the season, it seems, we’ve been chasing the weather. It’s finally caught up to us.

Boats headed from Asia to South Africa on a northerly route across the Indian Ocean, as we are, take off while the northeast monsoon gives a nice ride to the west. December is fine, although you wouldn’t want to cut too close to the end of the previous monsoon (and accompanying cyclones in the Bay of Bengal). January is great. February is fine, but the later in the season you depart, the lighter the trade winds, and the harder it is to sail the duration.…

Teeny Tiny Sailing

2 Mar

Hello, everyone! Sorry for the prolonged absence. My lungs and I had a serious disagreement. They decided they would be happier outside my body, and attempted to cough their way to freedom. I was of the firm opinion that we would both be better off if they stayed inside my chest. That is just the kind of hard-line organ traditionalist that I am. Eventually they saw things my way, but it took three weeks and a lot of coaxing.

By Sunday, I was well enough for an outing. Erik saw his chance. He has been determined to try out the sailing dinghies we found, and mounted a campaign of persuasion.…

Iridium GO! + PredictWind for Totem’s Indian Ocean debut

27 Feb

PW5

Not long before leaving Malaysia, we purchased an Iridium GO!. This was somewhat unexpected because Totem has long been a radio centric boat. Since we started cruising in 2008 we’ve relied solely on our HF radio for long distance communications: it has met our needs, we value the community of an informal radio net at sea, and we are grateful the safety net of land-based hams such as the awesome Pacific Seafarers Net.

What changed?

But this past year, paying close attention to the progress of boats along our intended route in the Indian Ocean, we were dismayed to hear how much trouble they were having connecting to land-based stations for the purpose of receiving updated weather data over PACTOR modems- to the point that we know radio-centric boats that relied upon sailing in company with those carrying satellite based systems on board so that they could to receive updated weather forecasts.…

METS 2014: Navico GoFree, Simrad IS35, Victron Bluetooth, LCJ Capteur BaroPlug & more

Earlier this week we published Henning Dürr’s report on METS 2014 and now here’s what Kees Verruijt found.

Navico GoFree cloud content and services
The Simrad NSO evo2, NSS evo2, B&G Zeus2 and Lowrance HDS Gen2 Touch MFDs will all get a January software update that allows users to buy new charts, update software, and more directly from their boat displays. Moreover, GoFree is being upgraded to a separate “brand” that covers all the cloud-enabled content and services offered by Navico on all three “hardware” brands…

The first big step is to make the existing GoFree WIFI-1 wireless bridge — which previously provided only a closed loop WiFi connection between mobile devices and an MFD/sensor network — also able to act as a WiFi client to an internet access point.…
