A few years ago, a similar circumstance happened in Winter Harbor.
An ocean-racer failed to detect the usual signature of an approaching thunderstorm, and saw the futility of trying to outrun it.
He came close to shore, tossed his anchor and anchor line out through the hatch
and proceeded to drag his anchor throughout the storm until he was out of sight.
Nobody knows how many water-lines he damaged or disrupted during his escape from the "sudden" storm.
