RedactedNarrative: The vessel, a 31' Carver yacht with five persons on board, was operating astern propulsion in Lake Ponchartrain near Breakwater Park in New Orleans,  approaching a disabled personal watercraft (in an attempt to secure the watercraft)  which was situated against the rock jetty, when the vessel's stern grounded,  struck a rock, bending both rudders and breaking the flukes off of the portside propellor. The vessel's bow, pushed to port by a strong northeast wind, was pushed against the jetty, the entire port side of the vessel coming to rest against the jetty. Attempts to pull the stern back into deep water  using another personal watercraft did not work. The vessel was then moored to the jetty and both personal watercraft were then tied to the yacht. The five persons on board then walked out on the jetty and abandoned the vessel. The moored vessel then sustained major hull damage over the next day due to wave action and interaction with the jetty. At some time the vessel took on water and the engine and generator were partially submerged.
