RedactedNarrative: On July 22, 2016 approximately 1230 Hrs. The vessel Hard Core II departed Solomons Island MD. The vessel captain was accompanied by his father.  Operator was heading south bound in the Chesapeake Bay near Wolf Trap Light.  Operator observed his vessel losing power and heavy exhaust from the starboard engine.  Operator stopped the vessel to investigate the problem.  Upon Operator opening the engine room door the starboard engine caught fire and burned through the cabin floor igniting the sofa setting above the engine.  The vessel was towed to the Town of Cape Charles Harbor by USCG Station Cape Charles.  The cause of the fire was due to the exhaust pipe partially separating from the turbo on the engine.
