RedactedNarrative: According to vessel 1 owner, on board at the time, fire began on vessel 1 shortly after he had heard the bilge pump activating.  In addition, vessel 1 owner saw smoke coming from console area in cabin shortly thereafter.  Once smoke seen, vessel 1 owner turned off vessel power and informed VYC dock master of situation.  (Vessel 1 owner stated that no fire extinguisher was used due to the fact that he did not want to fan the flames with additional oxygen by opening the center console unit where the smoke seemed to be coming from.)  VYC dock master then turned off power to dock.  Within moments, vessel 1 began to become engulfed in flames.  The flames then, in turn, spread to and damaged remaining vessels listed in this report.
