Friends have their propane bottles in an open rack, beyond the transom, but the rules say they should be brought inboard in a sealed locker, for "better drainage"?
I use 1/4 inch sch 40 thick walled stainless pipe , but the rules say I should switch to flimsy copper or rubber ,then have to worry about bulkhead chafe, something which is impossible with stainless pipe.
I can easily reach my propane tanks from my companion way, but the rules say I should use a far more complicated electrical device. I have a high pressure stainless ball valve shut off in the cockpit, but the rules say I should not have this alternative option.
The rules say that everything within 27 inches of the cook stove should be flame resistant, yet in 40 years of cruising, I have never once seen this done in any boat. Have any of you seen it?
Fortunately, in Canada, they would need a search warrant from a judge, which I could challenge, to come aboard and check my propane system. Then I could argue that the requirement that I use the less safe system that they advocate, is a violation of my charter right to life liberty and security of the person.

As far as I know, the main reason for not having propane bottles on the transom is in case you are hit from behind by another boat. I realise that this is a very small risk.

"The rules say that everything within 27 inches of the cook stove should be flame resistant, yet in 40 years of cruising, I have never once seen this done in any boat. Have any of you seen it?" Not unless teak is consider a flame resistant material

We've been through this several times in SN. The difference in the amount of water produced by an ethanol stove verses a propane stove is absolutely trivial.

Never forget them. Do something to prevent it from happening again.

I think a propane stove with the proper installation can be very safe. Nothing beats the convenience of propane.

For weekend use alcohol can make sense for some and as posted the total cost is less.

I have used alcohol and kerosene in the past and didn't like either - but the kerosene was better than the alcohol.

I have cooked on a propane Force 10 3 burner with oven/grill for years and wouldn't give it up. As a liveaboard it gets daily use.

A belated question

I wish I had caught this thread a few weeks ago...

I am concerned about my propane system as set up by a prior owner. I have a Seaward propane locker installed in the starboard cockpit locker. The Seaward is a nice unit (and they have great customer service), but I have always understood this particular design to be one that should be installed on deck. Mine has a drain in the bottom of the locker that goes directly to a dedicated through hull fitting located just above the water line when the boat is not heeling. This fitting is below the waterline on a port tack. The bottle feeds a three burner stove in the galley. An additional problem with the current setup is that the propane box blocked easy access to the cockpit locker. I couldn't even get into the cockpit locker to do any maintenance until I recently lost 60 pounds (let's just call me "gravitationally challenged" - I have more to lose!). The thought of getting in and out of there in a seaway is frightening.

On my good old boat (Allied Seawind 30), there is no space for this box on deck. I thought I had a solution when I came across the Torrid Bottle Mount for a 6# aluminum propane tank. I would put the bottle on the pushpit rail, put the regulator / solenoid in a watertight NEMA box also on the rail, run the hose from the solenoid directly to the stove through vapor-tight fittings on deck and in the bulkhead belowdeck between the cockpit locker and the main cabin. The solenoid wiring would run separately to the switch.

I bought the new tank, regulator, hose, solenoid and was getting ready to order the mount when I saw posts in this thread that raised issues about mounting a bottle on the rail.

So, finally, my question:
Should I keep the current setup, go with the bottle on the rail, or is there another solution I'm not seeing?

Feel free to critique my plans - I'd rather get flamed here than on the boat

Thanks in advance... Bill

I don't think there is anything wrong with a rail mount. It is however vulnerable to damage, as are BBQ's or anything else rail mounted.

Another option might be a box on the aft deck inside of the rail.

The factory installation in my Bristol 31.1 has the drain blocked on port tack if you are heeled over sufficiently. This also results in salt water in the locker which causes corrosion of the bottles. The best solution I could think of was to have smaller bottles, and raise them up on blocks. Alternatively, reef earlier!
