RedactedNarrative: V1 was recreationally cruising off the Gulf of Mexico in Sarasota County when fumes started coming from the cabin of the vessel and the Carbon Monoxide alarms started to come on due to failure of starboard motor. Owner/operator of V1 turned off engines and everyone went to the stern of the vessel and put on life jackets. Sarasota Fire Rescue and Sheriff's Office rescued the subjects off the vessel to safety. Sea Tow towed in vessel.
  
  At approximately 3:30 P.M., the 37 foot Tiara (Turtle Vision) had left the Crow's Nest in Venice and went offshore through the Venice Jetties. They proceeded to cruise about a mile offshore north towards Big Pass. The Carbon Monoxide alarms started going off. 
  
  They proceeded to open the hatches of the cabin but the alarms still sounded and Operator lost power of the starboard motor. The occupants then started noticing smoke coming from the cabin of the vessel. Operator turned the vessel off and wife directed all the occupants to move to the stern of the vessel and put on life jackets. 
  
  At this time, Operator hailed for help on Channel 16 on the VHF radio and other occupants started to call 911. Operator proceeded to launch the dingy off the vessel in case they needed it and got his fire extinguisher ready. A good samaritan vessel came and rescued half of the occupants and put them on their vessel and when Sarasota SO arrived on scene they rescued the rest of the occupants and put them on the deputy's vessel. When Sarasota FR arrived on scene they thoroughly inspected the vessel and found the cause of the incident (report is attached). 
  
  Per Sarasota FR, the starboard engine was found with oil leaking from the bottom of the engine block. The engine appeared to have blown and spilled oil on the heated engine which produced smoke. Sarasota FR completely ventilated the vessel. While all occupants were taken to shore by Sarasota SO.
