I'm getting away with 16 sq feet of solar for my 48v group 31 agm bank on my ericson 29. It keeps it topped off, but I mostly sail. Wind and solar would be ideal, also still working on wind. To get the real estate I built a stainless steel rack overhead mounted to the transom.

I have an Electric Yacht system in my Victoria 26, similar mooring situation as you. Just so you're aware, if you're running a 48v system, you'll need a fair amount of solar panel real estate--about 18 sq ft--to charge the bank--not an option in my opinion. Your best bet is a wind turbine, and I have yet to go that route. Instead, I tend to pull my boat off the mooring and dock it for a 6 to 9 hours while it's hooked up to a portable generator.
AGM batteries need to be maintained (topped off)--I've had to replace mine once already (after 4 years). I'm not sure there's a better option. Lithium would be even worse in regards to the intermittent charging schedule.
