Large boat fire - GIF

[sossol]

But seriously, the boat is probably "on the hard" and not on a trailer. Instead it is cribbed up in place timbers or on big "jackstands"

I assumed that it was mounted. The lower half is kinda blocked from view, but it's sitting low enough to practically (or literally I suppose) resting on its keel, and the bow is closer to the wall (I'm assuming that it's not typically trailered stern-first). Even so unless it's bolted to the ground it could be dragged. It would probably fall over but it's already trash, so there's no point in being gentile. Best to save the building and other boats not presently undergoing rapid and uncontrolled oxidation.
