Wired


Our replacement electronics required a complete refit of navigation instrumentation, along with rewiring the boat with new sensors.  If you never thought to imagine how much wire weaves through a boat, just take a glance at those two huge PVC runs in Reach and you'll begin to get an idea.  On a catamaran, these trunks lie across the boat in roughly an "H" shape.  When Mark redesigned our new Maretron-based NMEA 2000 network, on paper it looked like this:



  ... but in the real world, getting it there looks like this:

All of the navigation instruments (with the exception of AIS) are NMEA 2000 and virtually plug & play.  This is the new universal standard out in the field (albeit 10 yrs late?) that allows for a multi-component, multi-vendor sensor suite.  We are installing a powered, Maretron backbone through the boat ("H" shaped) that can accept any NMEA 2000 compatible instrument sensor now or in the future.  Then we can read the output of any of these sensors on  programmable, multi-functional displays.  It's amazing how far these electronics have come from the proprietary, single-vendor solutions.


Our new navigational kit ~ each "talking" to each-other on all displays and chart-plotters ~ contains:

  • Maretron NMEA 2000 backbone
  • Maretron ultrasonic wind indicator (too cool - see what Michele is holding in picture above)
  • Airmar 20* tilt-down depth-sounder
  • Airmar speed/temp transducer
  • Maretron GPS
  • Standard Horizon VHF with AIS
  • B&G multi-functional display
  • Furuno radome
  • Furuno radar/multi-functional display
  • Raymarine autopilot ram
  • Simrad autopilot controller
  • Simrad autopilot/multi-functional display
