RedactedNarrative: Operator/Owner of boat was out with 6 other friends at Shake the Lake.  After the fireworks, they stayed out, including during a very strong storm.  Strong winds, hail, and heavy down pour.  Due to the fact that the boat was at maximum capacity of occupants (7) plus gear, and the amount of rain, this caused the boat to sit very low in the water.  Operator claims a boat came by and a wave swamped them, this was able to be confirmed.  The water was still choppy and this Officer believes the bilge pump was not working, but could not confirm.  The boat did have a foot bilge pump, which makes the Officer believe the electric one was not functioning.  
  Primary cause of incident:  Stayed out during storm.
