Power shouldn't be a problem w Genset
I have a 5KW Northern Lights on my 356 and use a Farberware small (4 cup) electric percolator. I don't know what the draw is, but you should not have any problem running it, computer, charging phones, TV, HVAC and other electical items like elecric clocks. I use my genset on every sail to run the HVAC. I have a great sound shield so it is very quiet. We have never had a problem with power. We have a standard off the shelf toaster and it also has never caused a problem. We only have one 30 Amp circuit at the dock and parallel the two on-board circuits. We sometimes have a problem with the coffee maker and hot water heater which trips our boat breaker. That does not happen with the genset.
