RedactedNarrative: Subjects were on a recreational fishing trip from the south-end to the north-end of Lake George.  Initially south-side of the lake was manageable and calm.  As the subjects completed their activities on the north-side of lake, the weather had changed with a significant wind coming from the south.  As they headed back south across the lake, it became increasing rough.  The operator was maneuvering the vessel about, when the engine bogged down.  This allowed the swells (water) to enter the stern of the vessel and eventually swamp and overturn the vessel.  Both subjects abandoned the vessel and treaded water until 'Tow Boat" pulled them to safety.
