My guess would be an on-board heater or shore power cord overloading due to an electric heater. Another possibility is a frozen bilge pump with the wrong size fuse...

We lost a 56' Hatteras here a month ago, due to a portable heater....

I've left my boat plugged in all summer with A/C running often.
I would be willing to bet the difference is that I NEVER exceed 20 amps on the fire hazzard, er excuse me, hubbel twist lock plug.

Guys,

If you need to let your charger on when unattended, here's a simple trick to avoid problems if you don't need systems running 24/7.

I use a house timer with my digital charger. It's a 10 amp per duel battery charger. I set my timer to 15 minutes a day, for the first five minutes, the charger is pushing anywhere up to 10 amps per battery while seeking the state of charge.

For the next 10 minutes, it acts as a float (trickle) charge for topping off. I've been doing this for twenty years now. I get 5 to 7 years life from my batteries.

Just my opinion to avoid electrical problems.

Battery Charger? That is just speculation. The ultimate protection against fires in the electrical system are the circuit breakers and a healthy dose of good sense not to overload the circuits.
