I'm outfitting F&P to be fully self-sufficent. When I received her all of the 'quality of life' energy loads such as kitchen appliances are 120v. Perfect for sitting at the marina between races, less than ideal for living off-grid. This means converting nearly every 120v load over to DC operation (12v, although 48v is a future goal). Ideally, there will be no essential 120v loads (Ryobi tool battery chargers are a good example of an acceptible non-essential 120v load) - low amperage and not worth the time and expense to replace with a 12v counterpart.
As much as it would make my heart happy, I can't afford to convert some systems such as cabin heating and the engines to electric. For now I'm stuck burning dinosaur bones. Here is a chart of the various workloads and their energy sources.
Energy Loads
| Dinghy outboard | 12V standalone battery |
| Scuba tank compressor | 12v house batteries |
| Diesel heaters | 12v house batteries and diesel |
| Engines (2 x Suzuki DF20AS) | 12v AMG starter batteries and gasoline |
| Stove | Alcohol |
| Freezer | 12v house batteries |
| Interior Lighting | 12v house batteries |
| Exterior Lighting | 12v starter batteries |
| Chart Plotter | 12v starter batteries |
| Autopilot | 12v starter batteries |
| Radar | 12v starter batteries |
| Anchor windless | 12v starter batteries |
| Water pumps | 12v starter batteries |
| GPS | 12v starter batteries |
| Backup GPS | 12v house batteries |
| Backup chart plotter | 12v house batteries |
| Energy management system (Victron Cerbo GX) | 12v house batteries |

Energy Sources
| Source | Supplies |
| 8 gallon fuel cell | Diesel |
| 35 gallon fuel tank | Gasoline |
| Shore power inlet | 120v @ 30amps |
| Victron Multiplus | 120v and 12v house loads, and charges house batteries. This is a smart hub that converts energy sources and loads (a mix of mostly 12v and some 120v) on demand. |
| Wind turbine | Starter batteries |
| 2 x 100 watt solar panels | Starter batteries |
| 2 x AMG 12v starter batteries | Essential, non-house loads |
| 6 x 100 watt solar panels | House batteries |
| 2 x 314 amp hour LiFePo4 batteries | House loads (e.g. non-essential quality of life loads) and 120v off-grid loads. |
