RedactedNarrative: I, Officer, of the Florida Fish and Wildlife Commission received a call of a capsized vessel (V1) while on water patrol in Monroe County with Officer. We received the call when we were patrolling on the ocean side of Long Key Bridge and went en route to the location of the bay side of Long Key Bridge around mile marker 64 of US1. We found the vessel capsized and attached to another boat nearby. The capsized vessel was attached by line to a charter boat which occupied the four persons previously aboard the capsized vessel. The four males got in the water and flipped the vessel (V1) over as the charter vessel towed it quickly to the hotel they were staying at. Another patrol vessel operated by Lieutenant gathered the four persons and took them to the hotel. The operator claimed that they had taken on water from the rough sea conditions which quickly filled the boat and forced them to abandon their vessel.
