RedactedNarrative: On April 3, 2015 at approximately 11:38 AM, while on water patrol bayside of Stock Island, we were notified by dispatch of a vessel taking on water approximately 7 miles north of Key West. Myself and Ofc. arrived a the coordinates provided by Dispatch at approximately 11:52 AM and observed an approximately 36 foot vessel partially submerged with 1 adult and 3 children in a small inflatable dingy and 3 adults still on the vessel. We moved along side the vessel and transferred all subjects onto our patrol vessel. We verified that none of the individuals required medical attention as Officers arrived along with vessels from USCG Key West and Sea Tow. 
  
  We transferred the 5 female subjects (2 adults and 3 children) to Ofc. larger vessel and proceeded to USCG Station Key West. When we arrived at USCG Key West, operator provided a written statement (attached). Per Operator's statement he was operating the vessel from Key West, bound for Ft. Myers. Operator said he saw what he thought was a weed line and observed another vessel cross it. When he followed, traveling at approximately 25 mph, there was a large jolt when he crossed the line. He immediately shut down both engines and the vessel began taking on water. He called Coast Guard and moved the children and elderly female into the dingy. Operator stated that he tried to pump the water out with a hand pump but the water was entering too quickly. 
  
  The vessel, FL6261LL, a 36' Doral cabin cruiser, while traveling from Key West to Ft. Myers struck the East Jetty in the Northwest Channel, approximately 7 miles north of Key West at coordinates (approximately) N24 37 827 W81 53 507. The starboard propeller and rudder struck the jetty and the vessel began taking on water. 
  
  All subjects were wearing PFD's when we arrived on scene. All individuals were transferred to our patrol vessel. None of the subjects on the Doral were ejected from the vessel. None of the subjects required medical attention. When we arrived on scene the vessel was approximately 10% submerged at the stern. When we departed the scene the vessel was approximately 80% submerged (see attached photos). 
  
  Sea Tow towed the boat back to Robbie's Marine, Stock Island.
