Re: "Not an electrician" needs wiring critique.
Having read back through this, I am going to have to agree with the fact you are making the AC side of the wiring way more complicated than it needs to be. Unless you are planning on operating a toaster oven and hair dryer at the same time with, you could probably get by with one AC 15A circuit for the whole boat. Look for a 30A main CB with two blanks for CBs for a future second run, but I think it is overkill. I would look at ways to avoid needing an inverter, like bringing a laptop or Ipad to watch movies. Inverters are inefficient and carrying a TV on a 27 foot boat seems like a waist of needed space.
The only rationale for needing an inverter on a small boat would be a blender or coffee maker and you would need to probably run the engine while operating these items.
Edit: I just went back to look at the diagram you have and it shows an outboard as your engine? I am under the impression the amount of electrical power you can expect from them is minimal, even more reason not to be spending your energy when on the hook frivolously. Unless you are going to install solar you should probably leave the inverter at home.
