I'll go ahead and speculate (some more).
At ~11:00PM, the operator of left a residence in Tuftonboro (a town only a hundred watery yards from Wolfeboro), headed SE, passing a flashing-red marker 19, failed to turn South, continued a hundred yards until crushing the victim's dock with its 20 tons, flew over the
HackerCraft (
Dukes of Hazzard style--hat-tip to
Codeman671), depressing the
HackerCraft into the water--yet damaging the helm severely*, ripping through the pumpkin-colored boat cover (collecting part of it in the
Searay's crushed starboard propeller), fleeing until running aground nearby, telephoning the party of the Tuftonboro home they'd just left, got a return lift to the same residence, thereby escaping authorities' scrutiny of the operator's condition. (Whether affected by alcohol or drugs).
The
Searay could have piles of "empties" abandoned inside it.

my recollection (and one old photograph) has the HackerCraft docked on the northern (other) side of the dock, wrapped in a pumpkin-colored boat cover.
Those Tuftonboro residences bordering noisy highway 109 are a haven for local (and visiting) noisy oversized boats.
