Investigation at the scene revealed:  Vessel #1 was traveling north in the Grassy Sound Channel in Middle Twp, Cape May County.   As it approached the Grassy Sound Marina, same caught on fire.  Vessel #1 lost power and began to drift within the current.  As I arrived on scene, a good samaritain already had a tow line attached to the vessel and towed him away from the Grassy Sound Marina to prevent the vessel from causing damage to other vessels.  I took over the tow and towed them back to Grassy Sound Marina once it was confirmed that the fire had been extinguished.  
Inspection of the vessel's engine compartment revealed charring and melted components on the engine.  It didn't appear that the fire caused any structural damage and I was unable to determine the cause of the fire.
