Operator of vessel #2 was riding with a friend and was heading into the canal from the lakeside beach entrance going toward the riverside boat launch.  At that time vessel #2 was following a Sea Doo (vessel #1) with a man and his wife and children in it. The operator of vessel #1 took off down the canal making wake which vessel #2 did the same.  Both vessels slowed down for a small dingy to let it pass.  The operator of vessel #1 suddenly decelerated to a stop, and vessels #2 was following too close to stop or avoid hitting vessel #1.
