RedactedNarrative: Operator was cruising back to his homeport. The wind and current created a steep and large chop. The vessel dropped off a large wave and a plank (9ftx5") popped.  The operator noticed his vessel was sluggish and observed his bow was at the waterline. He attempted to retrieve PFDs but the compartment was flooded. The operator called mayday, exited the vessel with two fenders and his girlfriend. The two occupants were rescued by a passenger ferry. No injuries.
