If the lazarette isn't sealed the box will have to be and it has to be high enough to drain above the waterline at an angle of heel as well. If the box ends up at the top of the lazarette it blocks access to the lower part. I have seen the small lockers Catalina used on some of the 30's and don't find it a great solution.

Rbasi, that black tubing looks like high-pressure gas hose. Is the regulator inside the PVC, behind the boot? And sorry if I'm missing it, but I don't see a vent hose... If the regulator is inside that PVC pipe, IT needs a vent.

I'm also not sure why people are saying that a locker with a propane tank inside needs to be sealed. Typically storage containers for propane tanks are not more than cages, so if there is a leak the gas will be dispersed into the atmosphere, rather than mixing with air in a sealed container (which is by definition a bomb). Edit: A sealed locker WITH a properly sized vent to the outside air, WITH a screen at the end would be OK, is that what other posters meant? But I know of no requirement for the bottle to be in a "sealed" container.

Of course, it's Friday, and I've had a long week, so if I'm missing something obvious, please explain.

A propane locker in the cockpit doesn't have to have a gasketed top but one installed in a lazarette does as a leak could fill the locker and through any openings into the boat.

Re: Updating Unique Propane Tanks

Propane is heavier than air so either a locker in the cockpit or the lazarettes cannot be open, as leaked propane will find it's way into places you don't want it to (into the bilge or down the companionway steps into the salon). A propane locker on the outside of the boat, like off the stern, is a different matter and can be open, however that's also not consistent with best practice as it's subject to damage in a collision.

The safe approach, consistent with best practice and ABYC codes, is a sealed locker with a drain that leads directly overboard.

Here is the code :

Re: Updating Unique Propane Tanks

You are correct - I was thinking of regs (BSS) in the UK which only require the locker to be sealed to the level of the tank valve.

Certainly complicates things though when you have a sealed locker in another locker. Usually means a smaller tank also.

Re: Updating Unique Propane Tanks

I'm still kicking this can. To update: There is a drain at the bottom of this locker that exits the transom above the waterline, and I want to keep it. So, now I have a tank and a plan, just waiting for the end of race season to build this. I will mold it with glass to fit the new tank and existing holes. It might look a little weird, but it should meet standards and provide LP for the next 12 or so years.
