What you can't see is the top of the coach roof... 2kW of PV, including two Solar Stik Breezes. Internal electronics are pretty complex... each PV panel has it's own charge control to eliminate underperforming panels (i.e. shading) from the rest... Full Raymarine GS glass-panel control system, digital switching, triple transducers (each hull is monitored), and more. Steph even has a bathtub... with three ways to heat water (propane, engine, and electric).
Voyage got their reputation for building very austere vessels early on (Norseman designs), and they were perfect for long-term cruising because there was no "fluff" (wood paneling inside, brightwork topside, HomeDepot-grade systems, etc.) When I was a novice and building Empty Pocket, I was mentored by several cruisers that did some pretty amazing sailing in their own right. They instilled certain mindsets in me that remain today... "build a maintenance-free boat", and Empty Pocket was built in that spirit... Senergy is the fruition of that experience. There's been a lot of thought built into this one... it ain't for charter!
(And before someone else jumps on this... yes, state of the art lightning protection as well.)
