Fun Boating Yesterday...

Took the 280EC out yesterday for a quick run to pump the holding tank out so it doesn't freeze. At least, that was the plan.
The boat splashed off the trailer super-easy. It fired right up, ran great 15 miles to the nearest marina with a pumpout boat, and we anchored and shutdown for lunch. I ran the genny 30 minutes with the battery charger on to make sure the batteries are topped off, then shut it down to enjoy the quiet, but breezy day. An hour after we shutdown we tried to start the engine, but it refused. I noticed the batteries were only registering 12.3V at rest, and below 10V while cranking. Screwby.
I had the wife and 2 of 3 children with me, with number 3 expected at the bus stop in 2 hours. I called TowBoatUS, fired the generator back up, turned the charger back on, and it was blinking slowly - slow charging. Which means it thinks the battery is full. WTF? These are good Duracell AGM Marine Group 31 batteries. I also called the marina I was anchored right off-shore of, and they sent the poop-pump-panga straight out. TowBoatUS was an hour out, so I grabbed my voltmeter and started prodding. I recognized there was a short on the 12V helm circuit, and after looking around found the metal tip of our old cell phone charger in the accessory outlet. It was red-hot - how it didn't trip the circuit breaker I don't know.
Once I removed it the battery charger appeared to raise the voltage, slowly, above 12.5V. I swapped the battery switch to Combine and the engine would turn over faster, and sputter, but just refused to catch. After a bit of resting, however, the batteries had enough juice to start the Mercruiser 496 MAG, I called the TowBoatUS captain and he agreed the best play would be to run for the ramp vs. an hour plus tow. We made it back in record time - I pushed her 40MPH and she ran great. The batteries appeared to be charging (13.8V while running, 12.8 shut down), and we got back to the dock no issue. We even docked using spring lines against the wind like old pro's. That's where it fell apart.
Keep in mind the 280EC is a HUGE boat to trailer regularly, and I understand and appreciate that. Also, it was blowing 15MPH gusting to 25MPH across the dock/ramp, making it more difficult. Also, it's been 6 months and 3 days since the boat was out last - July 5th - thanks to an injury. Anyway, after much fussing it took my wife running the boat while I maneuvered on the trailer to get it hooked, then cranked in, all while a bystander tried to help by telling my wife what to do (that part was funny for many reasons). But we got it home. I took a few hours to work over the engine and found absolutely nothing wrong, batteries seemed charged, etc. Took the boat back to storage. I'll look at it again with fresh eyes in a week or two when we get another warm snap.

Go Steelers!!!
On my 24', I once tried to use a 12V coffee maker. It quit after brewing half a pot, but not because the breaker tripped. It only quit because the receptacle melted and lost electrical contact.
I had some power issues at my house about a month ago (lost the neutral coming into the house, what a mess!). Well, went to get my multimeter, it was on the boat! Gave me a reason to visit the boat! I do have another meter at home, but the one on the boat is my favorite to use.

Fortunate I was able to get out on a flight that came in from JFK so had no ice to worry about. But yes Virginia, it does freeze up down there.

It happens, and usually in lockstep with big hurricanes in September/October (which we've had 3 or 4 mandatory evacuations for in the last 3 years.
