RedactedNarrative: The two occupants launched the sailboat at the boat ramp.  They raised the Jib, but there was no wind.  They were headed towards the rocks near the edge of the ramp area and then pulled back towards the floats of the boat ramp.  They then raised the main sail and tried to tack, however the sail block was stuck and the main sail got over powered, snapped the mast and then capsized the boat.  Both occupants went into the water and climbed up onto the centerboard and that then broke.  Both occupants had PFD's on and swam back to the boat ramp floats.  
  
  A Good Samaritan vessel brought the boat closer to the boat ramp for the occupants, who then hauled the boat out of the water on their trailer.
