Dash panel not working

[dowhat]

Nothing on the dash is working. Gauges, horn, curt. lights, bilge pumps, tower lights, ballast pumps etc...
Started the boat yesterday and everything worked fine, went to launch today and now the dash panel is out. I checked all the fuses, breakers and battery conections and they are all good? Im hoping its something stupid that Im missing. Anyone have any ideas?
