We owned an early Carrie Craft. Had soluble oil in the hulls from the factory.

I didn't know you worked in the oil patch also.
Next year I will also be able to say "When I was in....."

I don't know the particulars on sinking boats, but working on what I DO know (kinda )

That boat looks to be about the same size as ours. That means it weighs somewhere around 32,000#...

That much weight displaces, at 8.3 pounds per gallon, 3855 gallons of water. Ergo, it seems reasonable that once there's that much water IN the boat, it will sink...

BUT, I don't know the particulars, what with one end lowering faster than the other. So, figuring the boat's doomed at half that much water, we're at 1928 gallons.

The boat sank within 24 hours-- that much water in 24 hours, 1928/24/60=1.33 gallons per minute... THAT is one healthy leak! But it's actually pretty close to the amount of water the 1/2" line going to my genny would let in if it for some reason came off or broke (or wasn't re-connected properly)...

I'm wondering if it might have been be a cracked/rusted weld, or other rusted spot that wasn't leaking before the stresses of the haulout/launch.

The way many boats are built, if they go down as much as say 6", bilge pump discharges and other normally-above-the- waterline fittings would become submerged and could back-flood.

1.33 gallons/minute isn't all that much; your fresh water pump can pump 3 gal/minute or more.

It really wouldn't take near that much water to sink a houseboat if it's not compartmented... Once the aft hatches or the ventilators go under, she's gone.

All the more reason for at least one BIG pump and a LOUD bilge alarm. A relay to the boats horns would probably be even better. It wouldn't take long before someone got tired of all the racket and did something.

The THREE pumps in my engine room add up to over 5000 gph (rated), and they're ALL automatic. They'll run a long time on the 700ah house battery bank.

They didn't leave the Dock Water on did they? They say more boats are sunk because of water line breaks when hooked up to the dockside water.

Coaltar epoxy will solve all of your problems? Don't believe it.

The last boat that sank at my marina was an old steel hulled Stardust. It had a one inch hole rusted through about 6 - 8 inches above the waterline. We had a big snowstorm - heavy and wet. It pushed the front of that boat down and over just enough to submerge the hole and down she went. It sank about eight feet down until it hit the cross bars on the dock. They raised it. It was a mess, but the people half way refurbed it and put it back in the water.

I can understand why more and more marinas are performing inspections.
