Vessel 1 was returning to Put-In-Bay to port via the Huron River at night.  One of the Occupants aboard Vessl 1 cried out that "there is an island in front of the boat" at which time the Operator slowed and turned hard to starboard to avoid collision with the island.  Despite this effort, Vessel 1 still ran aground on the southern tip of the island.  Investigation revealed that the island was not on Vessel 1's GPS.
