  • Commented on Heading Sensor, 3 axis vs. 2 axis rate gyro?
    PB200 heading sensor is motion corrected and gives great results compared to a flux gate. See this article from Ben http://www.powerandmotoryacht.com/safety/airmar-pb200-weatherstation However, it is for powerboats only. On top of a sailboat mast there are limits to how well it...
  • Commented on NOAA introduces Zones of Confidence; mind your ZOC
    Two thoughts. The bay is little more than 1 mile deep from the entrance. Isn't declaring the accuracy +/- 1600 ft, far far to cautious? With a clear nearby coastline you would think the surveyor knows were they are to...
  • Commented on Good instrument news: Garmin gWind Wireless 2 and Raymarine i70s
    1200 nits, Wow !...
  • Commented on The Passive Radar Reflector Solution for Sailboats
    None have AIS receivers. On the bright side, several now have their VHF radio configured with registered MMSI numbers and NMEA0183 integration with their GPS....
  • Commented on The Passive Radar Reflector Solution for Sailboats
    Once the fog partially lifted, the other 3 sailboats showed up clear on radar. Wonder what that was all about! I thought it took heavy rain and/or waves to diminish radar that much....
  • Commented on The Passive Radar Reflector Solution for Sailboats
    You have a very good point that few recreational craft have or use radar, and larger boats are equipped with AIS receivers. Having my own radar is far more valuable than the reflector when around other smaller craft, and AIS...
  • Commented on The Passive Radar Reflector Solution for Sailboats
    Crossing Long Island Sound in the fog and rain Memorial Day morning, was another opportunity to use this reflector. It takes about 2 minutes to rig it, even though I had not done so yet this season. Even thought the...
  • Commented on Airmar PB200
    PB200 is a great product for sailboats. I have a revised installation tip. If you are installing a PB200 now and have not purchased the wiring cable, see if you can choose the wiring cable compatible with the WX200 product....
  • Commented on Gizmo's new Firefly battery bank, working out the details
    Ben what changes are you making to your charging systems to support the new Fireflys? Do you already have heavy duty alternators? Tempurature sensors? Higher capacity charger? Larger power cables to your charging systems? Are Battery switch and fuse holders...
  • Commented on Autopilot question
    I am frustrated answering your survey. It is rejecting my submission because I am not answering mandatory questions, for example I can't answer about fuel efficiency, ease of cleaning, phone service, and other aspects I have not experienced. There is...
  • Commented on Wet cell battery temperature
    Sometimes the best insurance for some of these unusual problems, is the insurance you purchase from your broker....
  • Commented on Smartgauge battery monitor, RC proclaims "paradigm shift"!
    With the ability to measure draw, why not turn on the right combination of electronics to do the same thing? And if, no right combination to draw /20, then add a lightbulb or heater running on the inverter to the...
  • Commented on Smartgauge battery monitor, RC proclaims "paradigm shift"!
    Some thoughts about comparisons: In addition to knowing the SOC and the cost difference between the two, it would also be interesting to know what the power draw of these devices are. Especially for those instances our boats are drawing...
  • Commented on Garmin demos: GPSMAP 8600, ForwardVu, Fantom, Virb XE, Quatix3 & more
    April Fools no more, nearly all the key features of the PopGuard MFD from a 2011 April fools Panbo entry, such as a touch screen MFD that can work with software already installed in devices you already own, without having...
  • Commented on Iris NightPilot, Humminbird SmartStrike, Vesper AIS update, and Icom 7300 HF Radio
    Has RF direct sampling system made it into our normal boat radios? If no, is it expected too shortly or is it not applicable?...
  • Commented on Solar panels/ batteries
    The firefly needs an upgraded alternator/regulator also. There is a lot to be said for the golf cart batteries in that your electrical system stays simple....
  • Commented on Gizmo's house battery replacement: consulting with Cole, Collins, Calder, Schwab & you
    Firefly question. It isn't clear to me reading the literature, do you need to upgrade your power system to use this battery, and if so why. (1) Is the battery subject to damage from a standard alternator, or (2) Is...
  • Commented on Solar panels/ batteries
    Only if more solar power is generated than there is battery capacity to store it, will adding capacity help. For example getting you through some dark days. Some things to consider - Are you ok doing maintenance (adding water to...
  • Commented on Solar panels/ batteries
    A few questions that would help get a good answer. What do you perceive the benefit of additional battery capacity? What is the real challenge you are looking to solve? Is solar power being wasted because Which solar charging controller...
  • Commented on WiFi and cellular in Maine
    In Maine the book Ben wrote about, is tops, and Active Captain was valuable as well. On the coast from Liberty Island, New Jersey to Boston, I found Active Captain to be far superior than our two guide books, and...
  • Commented on Solar "Float" sizing?
    The DC output voltage of solar panels vary based on the intensity of the sunlight. You have a choice, if you put together solar cells that peak at voltages great for charging 12v batteries, they don't generate enough power on...
  • Commented on West Marine Expo, ACR LED Searchlight, Scanstrut USB, Navico Compass & Triton Gills
    Another great read. You are on a roll! Great find if the Triton is real, but it does seem like fantasy. I have no experience in the area of getting O2 from water, but in some other aspects like the...
  • Commented on Solar "Float" sizing?
    Solar controllers also dramatically increase the power you get on a cloudy day, by boosting the output voltage....
  • Commented on Boat Command: remote vessel monitoring for the app age
    Outstanding entry. Interesting product, great pics, and well written....
  • Commented on Gizmo's house battery replacement: consulting with Cole, Collins, Calder, Schwab & you
    Are TPPL lead acid batteries no longer a favorite of Nigel's, after Lithium Ion ? http://www.oceannavigator.com/January-February-2011/Battery-revolution/...

  • Commented on "Compass Safe" & Optimal sensor design.
    Place the GPS as close to the bow as you can Fluxgate? With all the electronics your obtaining, you don't have a solid state compass? It seems to be industry standard to write 1 or more meters on the instructions...
