RedactedNarrative: EPO’s responded to a boat fire at 4:10pm on 10-12-15 that was ongoing in the vicinity of Sakonnet Pt.  There were two subjects on board their 42’ Whitby sailboat.   They decided to board their dinghy after Subject1 was unsuccessful in putting the fire out.  According to reports subjects were underway headed toward Warwick from Mattapoisett, MA, when Subject1 smelled and observed smoke coming out of the blower vents.  He immediately opened the hatch to the engine compartment and observed flames.  Subject1 grabbed a fire extinguisher and attempted to put the fire out.  He was unable to do so because of the dense smoke and high temperature of the heat.  It was then that they decided to enter the dinghy to avoid harm by the fire.  The USCG arrived on scene shortly thereafter and transferred them onto the USCG 45’ Cutter without any injuries.   North Kingstown Fire also arrived on scene and was able to contain the fire. The vessel was a total loss.
