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).

Specific tasks

• Measurement of MFD box (9 7/8" x 9 7/8" x 5")
• 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
• Check on triducer dimensions and cabling -- can we use as is or do a 1:1 swap with another triducer of same dimensions (see more below)
• Is it possible to run a wired wind instrument? Seems some of the wireless options are not great (but also this isn't critical)

Major outstanding questions

• Zeus3S at 9" or Zeus3 at 7"?
• Cockpit displays
  • H5000 Graphic Displays x2? If so, how to mount in cockpit + we should check with B&G but we also might need the processor for it ($$) - see below
  • iPad mount that could probably work that into the existing mounts on the bulkhead

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.
  • Zeus3 : ($1400) https://www.defender.com/product3.jsp?path=-1%7C344%7C2028688%7C2028738&id=3748025
  • Zeus3s : ($2800): https://pro.westmarine.com/bg-zeus%C2%B3-s-9-multifunction-display-with-us-c-map-charts-19995752.html

• New triducer and wind sensor: Sail performance pack: ($1,599) https://pro.westmarine.com/bg-sail-performance-sensor-pack-20601076.html
  • Includes GPS antenna for B&G
  • Only downside is wireless wind. We may want to use the wired sensor and buy the other parts separately.
    • New speed, depth, temperature sensor triducer ($400) (existing one may work?) https://pro.westmarine.com/bg-dst-810-thru-hull-transducer-with-depth-speed-and-temperature-20268405.html
    • new GPS sensor ($300)(existing one may work): https://www.westmarine.com/bg-zg100-gps-antenna-20535100.html
    • New wired wind sensor: ($549): https://pro.westmarine.com/bg-ws310-wind-pack-with-20-meter-cable-and-interface-19237262.html but we may need a longer cable (it is only 65').

Wireless display options: it is nice to be able to have additional displays in the cockpit dedicated to speed, wind, depth. The current displays have been flaky and are Raymarine.

• H5000 system -- good for racing
  • How do we mount this? Can we build our own case? Should confirm housing is waterproof... if not need something like this.https://navpod.com/product/pp4400-c/
  • 2x Graphic Display ($1,199 x2) https://www.bandg.com/bg/type/instruments/h5000graphic-display/
  • x1 above and X1 Race display? ($989) https://www.bandg.com/bg/type/instruments/h5000race-display/
  • Probably need an H5000 processor:
    • Hydra ($2,199): https://www.bandg.com/en-au/bg/type/instruments/h5000cpu-hydra/
    • Hercules ($3,599) - integrates polars (https://www.bandg.com/en-au/bg/type/instruments/h5000cpu-hercules/)

OR:

• iPad mount on existing wireless display mount
  • ($57): https://railblazausa.com/product/railblaza-screengrabba-tablet-holder/

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.
