RedactedNarrative: On July 2, 2014 at approximately 7:30 p.m. Vessel #1, a 20 ft aluminum Xpress center console with remote steering was cruising westbound on the ICW between the Port of Iberia and the Delcambre Canal. Operator1 had the engine cutoff switch lanyard attached to his person and had one passenger with him. Vessel #1 was being operated on plane in the middle of the ICW and collided with a floating object that could not be seen by the operator. Upon impact, Vessel #1 spun around (facing eastward), causing the passenger to fall inside Vessel #1. The passenger received a minor scratch to the inside of the right knee as a result of the fall. Vessel #1 then came to an immediate stop and Operator1 observed that the lower unit of his 115 HP Yamaha outboard had been completely separated from the engine and the lower unit sank in the ICW as a result of the Collision with the floating object. Operator1 observed a long object that was stretched across the ICW after the incident. This object was floating even with the water's surface and was also submerged in some places and resembled a type of rubber coasted metal pipe. It appeared that the object was not fixed or attached to the ground. Operator1 believed this was the object struck by Vessel #1. PFD's were not being worn during the incident, nor were they used after the incident. Drugs and/or alcohol were not suspected to be a contributing factor of the incident.
