Where to Mount Propane Tanks

Have a center cockpit sailboat which does not have a propane locker. It had an old pressurized alcohol stove which I replaced with a Force 10 but where to put the propane. Mount on the stern rail? Deck mount in a LPG locker? I've been tearing out my hair trying to figure out the best way. Help!!!

Re: Where to mount propane tanks

Deck mount in a box or bag is probably the most straightforward way.

If there is an outboard venting locker that you can convert, this would be the neat solution.

Design for two flasks - then you can run from number one while looking for a spot to swap or fill number two.

Stern pulpit with nice custom Sunbrella cover. BBQ nearby to connect to the spare tank.

Re: Where to mount propane tanks

Deck mount the propane tank, for sure. Propane lockers are just baiting disaster. I am also of the mind that the propane should be turned off manually at the valve after every use. I do not think that propane is dangerous on boats provided that you do away with all those "safety" nonsense products like solenoids, sniffers, flame failure shutoff thermocouples, etc. None of these failure-prone systems afford true safety, only lull the user into a false sense of security. The best safety measure is to appreciate the dangers involved and act accordingly.

Do away with all the safety nonsense and propane willbe less dangerous? WTF?
I've seen 3 boats burn to the waterline, one was anchored over my anchor. (Always have the bitter end of your anchor chain attached to the boat with a small line so you can cut it loose.)

For starters Insurance Companies love to find reasons to not pay a claim and your suggestion would make them very happy as they wouldn't be required to pay.

The suggestion to place the propane tanks on the stern rail next to the barbie is also not a very good idea.IMO

Re: Where to mount propane tanks

Our boat has a deck-mounted horizontal tank. Sits in a cradle, strapped down. Easy and straightforward.

BTW, we have a solenoid with a switch in the galley. We use it, but we always turn the valve off at the tank when we're done cooking. The tank is easily accessed, so it takes all of 10 seconds to climb the companionway and turn on or off the valve manually. Makes for a pretty safe system.

That's exactly what we plan to do.

Re: Where to mount propane tanks

I always shut the solenoid switch off and when the flame went out I knew the propame had been turned off.

Deck mounting will be dangerous if leaking LPG can drift thru a nearby hatch or port. It is heavy and flows in a concentrated cloud. Like a thick river.

Proper locker is the way to go. A proper seaworthy sailboat will not have stuff like LPG bottles hung on the rail.

Safety always first. I agree in the redundency of this. We turn of at the we flip the solenoid, flip the breaker, and then turn off at the tank. The extra 10 seconds of going topside is for safety.

I would attach a vented locker box on the aft deck near the rail. We have two propane bottles. 1 is primary for the over/ stove, the second bottle is fitted with an attachment with low pressure valve at the end of the appropriate rubber hose to plug into venturi tube of our Magma Grill. This way we dont have to carry those 1 lb "bombs" on board whose needles sometimes get stuck in the open position and can be dangerous if not handled or stored correctly. The second tank can be used as a backup when the first runs out till it can be refilled ( mentioned above)

Re: Where to Mount Propane Tanks

Ours is two horizontal tanks in a sealed, vented locker within the lazerette. Solenoid is in the locker & switch in the galley. Redundant hand valve is in the galley. Seperate breaker for the solenoid only. We also ALWAYS shut off the tank valve in the locker. I like this set-up if you have room.

Be sure to read up on all of the regulations for propane on a vessel. It is simple but important. (or hire a pro)

If you go horizontal there is no overfill protection device required because they are not designed for horizontal tanks. Vertical tanks will need the overfill device and will most likely be sold with it installed. You cannot readily convert horizontal to vertical without replacing the valve and you cannot operate the tank in an attitude for which it was not intended.

Re: Where to Mount Propane Tanks

I just went thru a survey and got hit on three items on my propane locker, but was lucky and able to fix w/o much trouble. Some things have been updated in the last couple of years.

6-5.9.2: Pressure Relief Valve: A low-pressure relief valve shall be integral with each regulator.

6-5.9.5 Gage: Each reducing regulator shall be fitted with a pressure gage on the high-pressure side.

6-5.10(c) LPG Hose: In LPG or CNG systems, the lines shall be certified and labeled for the fuel used.

6-5.10.3.1: In LPG or CNG systems, the lines shall be secured against vibration.

tight to the hull interior, (c) Provided with a means to latch its cover, (d) Vented to the atmosphere, (e) Located so
that with its cover open or closed escaping vapor cannot reach the bilge’s, machinery spaces, accommodations,
other enclosed spaces, or accumulate in a cockpit.

6-5.12.1.2(a) LPG Vent Pipe: For LPG systems, a vent pipe of at least in. internal diameter to let outboard
without water traps through the hull from the bottom of the locker or housing terminating at the discharge point
above the waterline lower than its bottom.

6-5.12.2 Locker Access: Installation of gas equipment in lockers or housing shall be such that when the means of
access to the lockers or housing is open, the container valves can be conveniently and quickly operated, and the
