"Twenty minutes went by, and the drawbridge began to open for a sailboat," Pisciotta told FOX 13 Tampa. "(The bridge) began to crush the boat and me and my friends were in shock, not knowing how to react."

Officials say the group of boaters tried to get away from the rain, but the boat was under a part of the bridge with posted signs reading, "Unauthorized personnel prohibited," "Danger: Moving Machinery," and "No Trespassing; Violators Will Be Prosecuted."

When the drawbridge began to rise, the machinery began pushing on part of the boat, crushing the side, according to FOX 13.

No injuries were reported. 

The bridge tender was unaware a boat was underneath the bridge at the time, a Palm Beach County spokesperson told WSVN.
