RedactedNarrative: Operator stated his vessel was taking on water over the bow.  The operator stated the engine compartment quickly became flooded and the engine would not start due to the amount of water.  The operator stated the waves 1''-2'' were too high and kept coming over the bow of the vessel while they initially had engine power.  No occupants sustained any injures; the vessel and the occupants were located in the back of Moon Cove holding the vessel off the sandy shoreline.  I transported all occupants back to their vehicle at Boulder Harbor.  The vessel was left on scene.
