RedactedNarrative: On 7-1-18 at approximately 07:00pm EPO responded to RI Hospital Emergency to question Boat Operator regarding a boat accident that he was involved in earlier in the day.  Operator stated that at approximately 03:00pm he was operating his 28’ boat in the Sakonnet River northwest of Little Gould Island.  He said he was cruising at a speed greater than he usually does because he wanted to test the engine. Following a short acceleration, he observed the “high heat” alarm on the bridge.  He then went down in the engine compartment and while in close proximity to the radiator, the cap had blown off.  he was expose to a large amount of steam and sustained second degree burns on his chest, both arms, right hand and right abdomen.  A good Samaritan was in the area and assisted Operator and transported him to shore where Tiverton Fire and Rescue was waiting.  Tiverton Harbor Master arrived on scene to help bring Operator’s vessel back to its mooring in the Tiverton Basin.
