Refit has begun!

After quite an adventure getting the boat from Sanford to St. Augustine, she is now out of the water and getting an extensive list of projects done. Most are regular maintenance items, a couple of corrective actions, and of course the exciting bit being the electrical upgrades. Until this trip we had mostly only gone a few hours at most. We discovered that neither alternator has been charging along with other electrical issues. I am glad we are doing an extensive upgrade rather than trying to change things out one at a time.
We came up about 20NM short of St. Augustine when the engines started alarming for low power. The Yacht Rigger East sent someone out to meet us where we docked so they could switch out the start batteries for the rest of the trip. When looking at the wiring on the batteries, the electrician's quote was "there is a whole lotta what the hell going on in here."
After walking through the "final" plan (are any plans ever really final) this is the work list for the system.
48v generator replacement systemPXL_20250126_182601611.MP.jpg
The 12v GX70 will be located forward salon on the starboard side below the air conditioning control panel. The 48v GX70 will be just inside the aft slider above the light switches and will be the main monitoring station. This GX70 will also include the tank monitors.
Everything will be tied in to both my NMEA2000 network and my wifi network. This will allow monitoring from the helm underway (NMEA2000) as well as from home (wifi).
The installation will be featured in promotional material for Victron and The Yacht Rigger, so some promotional considerations have been provided. Everyone here on Carver Yacht Owners will be getting some behind the scenes info as well as the thought process that has gone into this project. Please let me know what details are most interesting and I will be happy to provide whatever information I can.
Why both a 25' and a 50' 30A cord instead of two cords of the same length? It turns out that we will normally only need to use a single 30A shore power with the new system. My home dock only needs the 25' cord. My plan is to use the 25' cord most of the time, but have the 50' available when needed. The shore power was going to need to be rerouted to the new system, so I'm taking the opportunity to change from the shore power cords being hardwired all the way to the panel to using a SmartPlug system.
Why Gobius tank monitoring?I was originally intending to go with Maretron, but there were a few reasons we decided to switch to Gobius:
- Maretron monitors require a Maretron display for configuration which adds to the cost.
- Gobius monitors integrate with the Cerbo GX so the tanks can be monitored without having the NMEA2000 network powered up.
- Gobius uses micro radar technology instead of sonar, which is supposed to be faster reading with less lag.
