I’ve made this diagram (which is also on the “About” menu of this blog) in case anyone’s interested.
I’ll try to keep it up to date if anything changes. The only addition I’m expecting this year is a fixed VHF radio, probably a Standard Horizon GX2200 because it has built-in GPS and AIS, and so can provide me with a ship proximity alarm without any further equipment.
Here’s a slightly out-of-date picture of where the switch panel and most of the connections are located, under the bridge deck. The main difference now is that I have an integrated digital volt/ammeter that is much more responsive.
