  I Officer with Florida Fish and Wildlife Commission, received a call from dispatch to respond to a vessel accident. The call was that a sailboat, later identified as YOLO, documented vessel 939947, hit the Sisters Creek Bridge. The Coast Guard was on scene and said they would be following them to St. Johns Boat Company on Hecksher Dr. I met with the Coast Guard there and was told that the boat yard could not accommodate them at that time so they would be going next door to Ft. George Island Marina. I met with the Owner/ Operator and his two passengers there. They explained to me that they called the bridge on the radio and that the bridge didn't sound any horns or have any visual signs for coming down. They said that there was another sailboat about two boat lengths in front of them. When it came down it hit the mast of the sailboat and broke it. I took a written statement from subject as she was claiming she was working the radio. I spoke with the bridge tender over the phone and made an appointment to meet with him the following day. He also let me know the bridge was inspected and sustained no damage. I met with the tender the following day and he explained that the vessel YOLO never called for an opening. Sailing vessel Cajun Queen called for an opening and was long past the bridge when he began his closure. He never saw the vessel YOLO. He said he followed his protocol for opening and closing the bridge looking out of the windows and looking in the mirror. He also explained that it is physically impossible for the bridge to close without the 5 horn blasts first. After talking to all parties involved and taking statements, I concluded that Operator was in violation of careless operation and violating Navigation Rule #5. Failed to have proper lookout. I issued him warning number.
