RedactedNarrative: Vessel 1 was anchored about 5 miles north of Conneaut Harbor.  Operator 1 noticed there was a significant amount of water in the vessel, and saw it coming above the deck of the vessel.  He then looked in the cabin area forward of the vessel and noticed a significant amount of water below also.  Operator 1 then had everyone put on lifejackets and contacted the Coast Guard.  A nearby vessel, “Fish N’ Fun Charters” took all four occupants on board for safety before Vessel 1 sank.  Vessel 1 slowly took on water and eventually sank.  The operator and all passengers were transported safely back to shore by another vessel, no injuries were reported.  The vessel is a complete loss.  The Operator stated they had been out the day previous and did not notice anything wrong.  He advised they had not hit anything or heard anything hit the vessel.  He was unsure if the bilge pump was running as by the time they noticed the water in the vessel, the outlet was underwater, and he could not hear if it had been running.
