RedactedNarrative: Operator of v1 traveling approx 30 mph with v2 coming around a corner at full speed (greater than 30 knots) in front of him approx 200-250 feet away.  v2 was cutting an eight foot wake and throwing bow water twelve feet in the air.  operator of v1 could not divert course because he was trapped between v2 on the port side and being pushed towards a gravel bar on the starboard.  Operator of v1 shut down as fast as he could and turned vessel into the wake.  v1 went over the fist wake ok but the second wake came over the bow and broke the forward cabin door, the third wake filled the boat and pushed the passengers into the cabin, fourth wake swamped the vessel
