RedactedNarrative: On 8-8-20 the vessel operated by Operator 1 was traveling upstream on the Powell River near the Peninsula.  Operator 1 stated that he was traveling about 28-30 mph when he noticed a large wave ahead, he slowed down to encounter the wave, which came up over the bow of his 20'' Malibu.  Operator 1 stated that two more waves followed closely behind the first causing the bow of the boat to become submerged, thus resulting in the subsequent swamping and capsizing of the entire vessel.  Operator 1 and five other occupants were able to exit the vessel unharmed during the incident.  The vessel was a total loss.
