RedactedNarrative: V2 (rental boat) broke down ocean side mile marker 74 in Islamorada.  The engines cavitated and lost power.  The boat rental owner (of Flying Fish Inc) was called and advised of situation but shortly after the cell aboard V2 ran out of batteries.  45 minutes later,  V1, of  the boat rental company located V2 and attempted to re start the engines. After several attempts, V1 was instructed by company owner over the phone, to tow V2 back to shore.  Unequipped with extra lines for tow, V1 secured to V2 by using an anchor line which separated the vessels approximately 40 feet apart.  V2 was advised that they were going to be towed into Caloosa Cove Marina on the ocean side just several hundred feet from where they had broken down.  While in tow and nearing the marked channel leading to the marina, V1 yelled at V2 indicating they were going to tow them into a private dock on the bay side of mile marker 74.  As both vessels proceeded towards the bridge, V1 centered and cleared both the new and old channel 2 bridge.  As V1 cleared and the bow of V2 approached the old channel 2 bridge, V2 yelled at V1 stating they were going to hit.  As V2 remained in tow and being pulled forward, the T Top structure hit the concrete arch of the old bridge causing it to collapse back toward stern ripping the center console off the deck.  The T Top structure pinned several occupants causing injuries.  As V2 was pulled away from under the bridge by V1, the occupants of V2 quickly demanded to transport the children and women on to V1 (the safe and intact vessel).  Operator of V1 denied the request but V2 insisted and transferred all to V1.  Upon arrival to the private dock, owner was waiting at the dock and took one of V2's adults, a block away to retrieve his vehicle.  The families of V2 assessed injuries and headed to Mariners Hospital for treatment. Once there hospital staff reported the boating accident to FWC.  No one from V1 nor owner called to report the accident.  V2 was unable to call due to the phone having run out of battery. Injured were  treated and released on the same day with no major injuries.  DOT has been notified to assess any bridge damage. subject owns both V1 and V2  ; subject1 :Sustained a deep laceration to leg requiring stitches.; subject2:Transported to hospital where xrays determined contusion to left wrist.; subject3:Transported to hospital where he was examined for injuries.
