Ouch.
It wasn't snow load. Would take several feet of ice (not snow) to push boats of that kind to where they take water over the coaming. Boats of that size can take a big wave over the stern / outboard well, or drop the rail into the water and not even feel it. Assuming it had an outboard (& well), not an inboard, and the well overflowed into the cockpit (not likely), then the cockpit water typically has to be 6-9-12 inches deep or more to reach the top of the bridge deck. But ... cockpit drains could have frozen then split and let rain/snowmelt into the bilge.
Most likely causes...and probably 2 or 3 had to combine to make it happen...
* thru hull fitting (head or sink drain or engine cooling water drain, or cockpit drain) or its hose came loose, or froze and split letting in seawater or
* engine heat exchanger frozen/cracked letting in seawater
and/or
* bilge pump not automatic, or
* bilge pump ran until it exhausted the battery or
* bilge pump failed, burned up, frozen (or its plumbing frozen)
AND
no harbormaster keeping an eye on things. This boat had to be taking on water for days before she went down. Someone should have seen her sitting low, and/or seen the bilge pump running continuously.
