You seem to be an order of magnitude away from what I consider normal for a small sailboat. 80W solar panel & 400Ah battery bank. Even the 'high output' alternator only puts out 70A max. Do people really need AC when away from shore? I lived in the Caribbean for years and never had it, its much cooler out on the water..

I follow cruisers and Youtube rich ones. Also, 6000Wh is 500Ah 12V batteries. AC is pretty rare on sailboats but does show up on nicer ones, but I get the impression nobody runs it except on shore power.

Also, when news say orcas are attacking small sailboats, I think they are comparing them to large yachts. And not actually small sailboats below 25'. I suspect most are 30-50' since that is most popular size for offshore.
