Downflood: the Good Ship Boris is sinking

In Sebastian Junger’s book The Perfect Storm, there’s a near-matchless description of how big boats go to the bottom. ‘The crisis curve starts out gradually and quickly becomes exponential,’ Junger writes of a boat wallowing and taking on water in a big sea:

The more trouble she’s in, the more trouble she’s likely to get in, and the less capable she is of getting out of it, which is an acceleration of catastrophe that is almost impossible to reverse… If there’s enough damage, flooding may overwhelm the pumps and short out the engine or gag its air intakes. With the engine gone, the boat has no steerageway at all and turns broadside to the seas. Broadsides exposes her to the full force of the breaking waves, and eventually a part of her deck or wheelhouse lets go. After that, downflooding starts to occur. Downflooding is the catastrophic influx of ocean water into the hold.
