RedactedNarrative: While adrift, with the motor running but in the neutral position, Subject was using a cast net to catch bait. At some point Subject's cast net became entangled in his throttle lever, which engaged the engine and advanced throttle. This motion caused Subject to fall into the vessel gunwale causing injury. Subject's vessel then collided with a crew vessel, which was moored to the dock. This collision caused Subject's vessel to pitch, ejecting Subject. The vessel capsized then sank. Subject was not wearing a PFD at the time of the incident. The vessel was equipped with remote steering.  The victim suffered broken ribs and internal injuries.
