A boat carrying two people ran into a breakwall in Sodus early Tuesday morning.
They hit the wall a little after 1 am.
Cory Donk, 23, was the man driving the boat and was charged with Boating While Intoxicated and Vessel Operator Failing to Report an Accident.
Thomas Gorsky, 50, was the other passenger on the boat and took off before police arrived.
Gorsky was later found on an island near the area where the boat crashed.
Gorsky said he passed out after the crash.
