RedactedNarrative: On 06-11-2021 at approximately 1637 hours, I observed smoke coming from Vessel 1 just outside of Windsor State Park. Upon arrival I located 4 subjects inside the boat with an infant child on board. I assisted the child and mother off the Vessel 1 onto my boat. The other 3 occupants were ok and did not want to board my boat. There was smoke coming from the engine compartment which was propped open. The operator said that they just launched their boat a were no more then a few hundred yards off shore when it started smoking. OPERATOR 1 used 1 fire extinguisher to put out the smoke. OPERATOR 1 said that he never saw any flames, just smoke. He said that it was his baffels that were smoking for an unknown reason. The only damage observed was in the engine compartment. Event was recoreded on AXON.
