Electronics Upgrade
From MITNA
The goal of this electronics refit is to standardize the communication protocol onboard Mashnee to NMEA2000, improve reliability of instruments, integrate radar and AIS consistently, and support racing goals. To this end, we have decided that we should upgrade to a B&G system because it has more advanced sailing/racing features than other MFDs (multifunction displays) and it integrates with our current radar. We want to keep the MFD visible from the cockpit (using the existing swing-out box, ideally).
Key components
- B&G MFD: key question: can we fit a 9" MFD in the box or do we need to stick with a 7". If the latter, we can only do the Zeus 3.
- New speed, depth, temperature sensor triducer (?) need to see if the current one is NMEA 2k, if not: ($400) https://pro.westmarine.com/bg-dst-810-thru-hull-transducer-with-depth-speed-and-temperature-20268405.html
- New wind sensor
Wireless display options
- iPad mount on existing wiressless display mount
- Sailmon wireless displays - really powerful racing features, can integrate over NMEA 2k with the below interface. It charges using a charger pad we can hook up to 12v via USB. A more expensive but more robust option; double benefit of redundant GPS signal; has IMU built in too.
- Display ($1,049): https://www.ronstan.us/marine5/product.asp?ProdNo=SM-MAX2
- NMEA2k interface (~$200):critical; needed to actually display speed, depth, etc. data. Can't find in U.S. but seems to be branded NavLink... -- https://shop.sailmon.com/product/max-nmea-interface-2000/
- Wireless charger ($48): https://www.ronstan.us/marine5/product.asp?ProdNo=SM-MAXCHARGE
- Screen protector ($37): https://www.ronstan.us/marine5/product.asp?ProdNo=SM-MAXSCREEN
- Mounting bracket: to mount on existing raymarine wireless slide piece -in the box.
Other possible upgrades (I don't understand what this does, to be honest)
- Triton edge sailing processor ($1500): https://www.defender.com/product.jsp?name=b-and-g-triton-edge-sailing-processor&path=-1%7C344%7C2028690%7C2028836&id=8049633
