Nah, I'm just not willing to take the chance. I experienced the first Propane explosion on the night of July 3 1947. I was 11 years old. There were only three marinas in the Los Angeles area, and this was the first Transpac after WWII. It is what is now 22'nd street landing in San Pedro. I was sleeping in the cockpit of my dad's boat, and we were on hand to watch the start of the race the next morning. About 11 PM, I awoke to an explosion--and fire at the end tie. The boat was named "Hawk" and belonged to one of the Hollywood stars. She was about 70 feet long, and rigged as a cutter--a little smaller than Windward and Patolita, but very similar. Seared on my memory was the owner's wife running down the dock, screaming, her nightgown ablaze. The Hawk burned to the waterline. I don't know if the owner's wife survived. Many years later, I was walking down the gangway to my boat in Alamitos Bay, and a power boat exploded one gangway over. The owner was on the flying bridge--and ended up in the water. He survived. There was no fire. A close friend, after a hurricane, was putting one of the cartridges into his portable stove, to heat some soup. Because the power was out--there was a candle burning in the kitchen. All of the butane came out with a rush, when he pushed the canister into the stove and the seal failed. He had about 60% body burn. I sat with his wife daily in a burn unit for over 6 weeks. He was on dialysis for renal failure--also had some pulmonary damage. But he survived and is still alive today. In my own practice I was called to treat kidney failure in two patients who had burns from propane explosions.....
Just not willing to take the chance. The solenoid valves are not 100% fail safe. One of my friends had two of the sensors (as I did--one under the stove, and one in the bilge.) His propane system developed a leak--explosion and fire--never did find out why the sensors didn't shut off the valves--but the boat was lost--they survived.
