RedactedNarrative: Smoke was coming from the front of the boat (inside). It is unknown exactly where the smoke was coming from. They do not remember hitting anything and did not hear any explosion.  The Operator shut down all power to the boat. He then tried to go down below with an extinguisher towards the bow but saw that there was too much smoke so then decided to go to the bow and climb through the hatch to put it out but by that time it was too late. One of the passengers was saying, "we need to jump".  The operator tried to get the safety raft and life jackets but it was too late.  The smoke and flames were getting worse.  He grabbed pool noodles and met the other 2 passengers and the dogs and they all jumped in the water.  A local fisherman was close by and he rescued everyone and headed back to shore.  EMS tended to all parties and transported them to Portsmouth Hospital to be evaluated for possible smoke inhalation. The boat was a total loss.  It was the home to the family on board. There was a 300 foot by 50 foot oil sheen where the vessel finally went down. The Coast Guard was notified and was going to check on the sheen daily. While speaking with the registered owner and his passengers they discussed that the only thing they had readily accessible to use as a flotation device was a green pool noodle.  The operator received a warning for PFD's not readily accessible and a warning for unregistered boat on State waters.
