RedactedNarrative: V1 and V2 (rental personal watercraft) were offshore of Palm Beach Shores.  V2 was stationary in the water when V1 came back to talk to her.  V1 came too close to V2 before Operator1 attempted to slow down.  The bow of V1 struck the starboard side bow of V2 and Operator2 before sliding off the starboard side foot well.  Operator1 recovered Operator2 from the water and took her directly to the beach where EMS transported Operator2 to St. Mary's Medical Center for treatment. Operator2 had a shattered kidney (removed during surgery), laceration to liver, minor rib fracture
