RedactedNarrative: V1 was heading south on the Gulf of Mexico about seven miles offshore from the Venice Inlet and collided with V2 heading north. V1 sustained major damage while V2 sustained no damage. Collision occurred due to heavy fog and very low visibility. There were no injuries during this collision.
  
  Officer 1 advised that due to the very low visibility they didn't need anymore units to respond on the water and that I can standby at the marine building. At this time, Officer 1 advised that there were no injuries. The mast on the sailboat (V1) was completely dismantled and the commercial vessel (V2) did not sustain any damage.
