Realizing I'm gonna have to get serious about this, I pull out the tide tables and turn on a light eliciting lots of complaints from sleeping crew but I find the tide will be running out in an hour. So, I wait up till then and finally get rid of the canister but never did get back to sleep waiting for the "Thunk, Thunk" again. Why didn't you just slowly open it up down wind, let it empty, then tie it up outside overnight? No wind. Seems like there would be something. None at all? All night? How about tying a weight to it and the boat, then opening the valve... it would sink down current of your boat, bubble along, then you could pull it back in. I thought boaters were all about creative thinking? Yeah, take all night to come up with a scheme to get rid of a little propane gas...... brilliant. Progressive "thinkers"..

People on the west coast have no idea how glassy still the Gulf of Mexico can get. When holding a leaking canister aboard a boat, time is critical lest the heavy propane get in your bilge. Even holding it over the side leaking could be dangerous. In this case, safety takes precedence over not littering. I took all of 30 seconds to figure out how to do it. If the propane tank is mostly full, it would float fairly low in the water. It wouldn't take much to get it just below the surface. I addressed the lack of wind, since it would be current that would keep it away from the boat. I guess you're not much of a sailor if you're unaware of the current direction? Sounds to me like you were panicked, and it didn't work. Then, you posted on here to satisfy yourself. |

Sounds to me like you were panicked, and it didn't work. Then, you posted on here to satisfy yourself. I guess I missed the part that described the source and nature of the gas leak. If it were a leaky valve, it would keep on leaking until there wasn't enough gas pressure left in the tank. At that point, the tank would be floating fairly high in the water. The leaky valve might not have allowed water to leak into the tank. All of Froggy's boating mishaps present to me as the ongoing saga of a boat owner who ignores maintenance or who juryrigs maintenance so as to get it done as cheaply as possible, without a thought to the longevity or propriety of a repair. I wouldn't leave the dock in Froggy's boat. If his boat has lifelines, they're probably made from plastic coated clothesline bought at wal-mart. |

Fixing things with what you have on hand and dealing with the unexpected are all part of international cruising, sometimes a big part. *The big mega yacht cruisers are maintained to a very high degree of reliability but they generally have an engineer in the crew and a big supply of spares on hand to keep things working. * Since we bought the trawler 7 years ago I've learned enough new skills, and acquired the tools, to be a junior tradesman in 3 or 4 different fields. 3% propane in air (by volume) is explosive. Think about that when you think of the size of your bilge and consider that concentration can rise quickly becaus eof the density of the propane. Then consider that when it explodes the gas then takes up 270X the volume of the previous air/propane mixture and you can see it can make a big explosion for a small amount of propane. A small leaking cylinder is a major safety hazard requiring immediate action. Even a few minutes of a leaking cylinder can turn your boat into a bomb. By volume propane is more explosive than gasoline and is explosive over a wider range of concentration so is more dangerous than gasoline vapor. You may not want to admit I am right but if thinking about it keeps you from storing a canister on your boat then I am happy. |

Reply: For those who think a 16 oz. container is not much, think how much you can cook on a 2 burner Coleman stove with just one canister. Or how long a propane lantern sheds light for with a single cartridge. |

How is said propane supposed to get in your bilge from below the water and down current? I'm still waiting for your answer. If it's so deadly, why did you worry about it coming back up current after you tossed it? |
