RedactedNarrative: Vessel 1, a 35 foot cabin cruiser (FL4512PH) was being operated during daylight hours (approximately 4:00 pm). Operator statement and vessel GPS information show the vessel heading north from the south end of Elliott Key towards the ICW in the Featherbeds of Biscayne Bay at approximately 25-30 mph. Vessel 2, a 26 foot cabin cruiser (FL5894LV) was heading west from Sands Cut to Homestead Bayfront at approximately 25-30 mph.
  Both vessels collided just west of Sands Cut . It is determined that Operator1, while operating vessel 1, failed to give way to vessel 2, which was approaching from his starboard side in a crossing situation as expressed in USCG navigation rule 15.
  Despite operator1’s late attempt to avoid collision by turning to his port side, vessel 1s starboard quarter collided with a glancing blow to vessel 2s port bow. The collision caused major damage to the starboard quarter on vessel 1 and paint transfer and prop marks on the port bow of vessel 2, and ejected female occupant into the water. Shortly after the initial collision, vessel 2 capsized for reasons unknown (vessel hull intact upon recovery), leaving the other two occupants in the water.
  Vessel 1 circled around and recovered all persons from Vessel 2. Vessel 1 while taking on water, proceeded to Homestead Bayfront with all occupants from both vessels. However, assistance from commercial salvage was required due to the vessel taking on water. All occupants of Vessel 2 were treated by EMS and refused transport. 
  Vessel 2 was recovered the next morning by commercial salvage and documented/photographed with assistance from Biscayne National Park Rangers.
