Converting rear Laz to be a LPG locker

Any useful advice on converting my rear lazaret into a LPG locker? Obviously plug and glass all the holes in the bulkhead, and install a drain plug in the bottom....

Re: Converting rear Laz to be a LPG locker

We have stern lpg locker, the only issue we have is the outboard drain can bring water in with following seas or when she "squats". I would think your Alberg would not have that issue.
We are converting the locker for storage, moving tanks to stern rail.
Good luck, beautiful boat!

Thanks. I looked long and hard at your CD30 before going with the A37. I hope you found a good home for her. I might see what would be involved with a stern rail mount for a 20# AL tank...

Re: Converting rear Laz to be a LPG locker

Thanks bluemoose she did find a great home, so that is a relief! I haven't done it yet but I thought to try a fender holder mounted outboard our stern to put a vertical 10-20 lb tank in. The fender holders are only 50 bucks and I can make a canvas cover to protect the tank and lines from UV. Just an idea.
Cheers,
Erika

Re: Converting rear Laz to be a LPG locker

Depending upon the tank capacity and dimensions, if you have sturdy stanchions or support columns around your pushpit you can use oversized stainless hose clamps around the tank and column. Appropriately sized thru deck adapters run through plexiglass used to replace glass in a portlite avoids having to drill through your deck to facilitate running hoses.

Re: Converting rear Laz to be a LPG locker

General advice is keep the gas outside. Probably good advice. Not a lot of corrosion issues on fresh water and seas are not usually monster. That said, our tanks are on the stbd inside the Laz. I hate the look of propane tanks on deck. There is a seperate locker with tight fitting gasket. The floor of this locker slopes to the drain/vent hole to the stbd side. The locker needs to be the absolute minimum volume required to house the tanks, valves and regulators. I see that you are in Toledo. We are in Muskegon. If you would like to come see the whole (legal) installation send a Private Message.

In the photos, on deck, you see the lazerette hatch facing aft. Tanks are on stbd below the deck and forward of the transom. Tanks are 10# Aluminum each. If your tanks are horizontal, you will not need an overfill prevention device. In fact special tanks with a bent dip tube are required and they must be installed in the correct orientation. You will get a decal for each tank declaring that it is a horizontal exempt tank. A bracket on the tank fits into a slot that secures the tanks to the bottom surface of the locker. The drain, vent hole is behind the aft tank (right tank). You can see the nice gasket surface around the lip of the locker. The gasket is on the locker door. Its not obvuious but there is high temperature insulation lining on the forward side of the locker. The main regulator services whichever tank is manually valved in. I have since had the hand valves on both tanks replaced. The regulator feeds the solenoid valve. You also see a branch connection that supplies the transom mounted grill. You can see the grill line & regulator in the on-deck photo. The output from the solenoid goes to a copper line without joints all the way to the galley. This pipe is calked at the exit to the locker. In the galley, there is a manual shut off valve in a cabinet above the range. In the foreground galley below the counter you see the fancy lighted hum-dinger lockable safety switch that enables the solenoid. (by the companionway) To operate the range: open the lazerette, open the tank locker, open a tank valve, close the tank locker, enable the dedicated breaker for the solenoid, enable the solenoid, open the hand valve, light the range. When not in use, we shut it all down including closing the tank valve.

I believe that you need all of this to be legal. (and safe)

Re: Converting rear Laz to be a LPG locker

My Columbia 41 came with a laz for the stove's alcohol pressure tank. It was about 4" too shallow to fit a standard propane tank. That is, the tank you get at the hardware store for the back yard grill. I added a 4" extension to raise the laz hatch. Now I just drop in a new prolane tank when needed. The laz came with a drain line. Very little else was needed to make the switch.
