So, I think the boat needs to be rewired. The batteries are two different sizes and rating (not good for batteries that are wired together in parallel)
It has a older battery charger for shore power to charge the batteries.
Shore power inlet is on the port side currently.
Put shore power on the starboard side, locate the electrical distribution panel on the starboard side between the seat and the berth.
The radio and the VHF radio Should fit in the wood thing where the door currently is. I also plan to add one of these to control the navigation lights, which should fit where the 12v DC plug is.
Overall, the plan is the upgrade the batteries to 4 either Trojan T-105, or T-125. Charged via an IOTA DLS-45-2. Install 3 new panels, Blue sea 8023, 8101, 8686. Move the shore power inlet to the starboard side, and use the new smart plug 30a connection.
More planing will result in a continuation of this.
