Battery and Solar Design

There will be at least two Vcc busses on board. Labeled, oddly enough, as Vcc1 and Vcc2. The difference between them is that Vcc1 is always on, at all times, and Vcc2 (through VccN) are selectable by Igor.
The main processor runs off Vcc2, but Igor (and Otto) both run off Vcc1. In situations where voltage levels are critical, Vcc2 will be switched off and the boat will continue on whatever course had previously been set, until either voltage levels are healthy, the specified "wake-up" time has elapsed, or there are critical issues which require Mother to get involved. A critical situation could be something like a dramatic wind shift, or an error such as a mis-reading from a sensor.
Latest on the hull
By Dermot Tynan, about 11 years ago.
Here's a quick sneak picture of the hull with the wiring harness complete and the decks sealed in place.
The keel is still only temporarily installed so the main compartment is again flooding with sea water. The bow is still slightly down in comparison to the stern, but this is mostly due to the flooded compartment. Also, the keel still hasn't been moved back, yet. That will happen this week.
