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: Make new box for 9" MFD (MFD dimensions 11.3" wide x 6.5 tall x 3.5" deep). Current MFD box (9 7/8" x 9 7/8" x 5")
- GPS, Triducer, and wind sensor (wired versions of b&g sail performance pack):
- Speed, depth, temperature sensor triducer ($400): https://pro.westmarine.com/bg-dst-810-thru-hull-transducer-with-depth-speed-and-temperature-20268405.html
- GPS sensor ($300): https://www.westmarine.com/bg-zg100-gps-antenna-20535100.html
- Wired wind sensor: ($549): https://pro.westmarine.com/bg-ws310-wind-pack-with-20-meter-cable-and-interface-19237262.html
- Micro-c backbone kit ($60): https://www.westmarine.com/lowrance-micro-c-backbone-starter-kit-14273858.html
- Any additional NMEA 2k cables (suggested is 1x2m and 1x5m)
- B&G H5000 system as supplement to chartplotter
- 1x Graphic Display ($1,199 x1) https://www.bandg.com/bg/type/instruments/h5000graphic-display/ How do we mount this? Can we build our own case and hang somewhere? what about data/power cable?
- May want an H5000 processor:
- Hercules ($3,999 includes H5000 Graphic Display) - integrates polars (https://www.bandg.com/bg/type/instruments/h5000base-packhercules/#prl_key_features)
Specific tasks
- Run NMEA 2k backbone from mast to the electronics
- Remove all other deprecated electronics wiring/equipment
- Connect vespermarine AIS to new NMEA 2k backbone
- Convert fluxgate compass seatalk NG to NMEA 2k. Confirm correct male/female end requirements
Major outstanding questions
- It may be worthwhile to see if by purchasing the Raymarine Micro-talk wireless gateway ($310) https://www.defender.com/product.jsp?id=3800935 we can make all the new instruments and these displays just work with a Seatalkng to NMEA 2000 converter. Then we can use the existing displays as is. Otherwise:
OTHER Option (but different system):
- 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.
