Propane locker problems

My present locker was actually designed for CNG and modified. Problem with it is that on starboard tack the vent is submerged so it is, of course not venting then. The locker is awash - though far from full, on starboard tack, and drains out when the boat is level. The seat at the stern of the boat is just a frame with open space underneath so I could mount a tank there. Would this allow enough ventilation? Converting back to CNG is not something I am willing to do. Interested in your ideas and thoughts.

If I picture this correctly, the under-seat storage would vent to the cockpit - not acceptable. Would be ok, if you could enclose it (or install a manufactured locker), and vent overboard.

You do picture this correctly, I had thought the under cockpit needed to be vented, but I have been told it is OK by some as the scuppers will vent the propane. I do not know.

Propane locker problems

From another forum where I posted the same problem. This seems like a good solution. If I need to cook, go on port tack where the locker is vented. Otherwise shut the valve and forget about it. At rest, I am vented.

Propane locker problems

You may be ahead of the game to simply run yoru vent line out through the transom near the center line of the boat. One of my gripes with the Island Packets is that thier propane locker vents are on the side of the boat, near the max beam, just above the waterline, for a boat that claims to be a designed as a passage maker, there could be days in a row when they might have the vent under water.

Propane locker problems

Jeff, we could add that this kind of propane locker design (found on a lot of H-R boats) generates some very colorful deposits on the inside of the locker where the steel tanks go...and this then dribbles down the hull, looking like a vertical racing stripe.

Bet you think I''ve forgotten; I haven''t. Patricia is now fully mobile and, while the tile laying project has begun, you''ll hear from me soon.

Its funny Jack, Just as I started reading your post, I thought to myself, "Self, you should probably drop Jack a note and see how hos wife is doing after her surgery and ask about the ''project''" I look forward to hearing from you.

Regards,
Jeff

Propane locker problems

Jeff,
From your post I understand that my problem is not unique. Some vents are underwater some of the time.

Propane locker problems

Why is venting to the cockpit not acceptable?

Propane locker problems

Hi, Terry - sure fun to Skype with you the other day.

I think you''d hear from the ''standards'' people that the concern with venting to the cockpit is that the cockpit well ''traps'' the LPG and the reverse airflow that can exist across a boat''s deck will result in leaking LPG down-flooding into the cabin via the companionway. This is accentuated in boats with a dodger above the companionway.

This of course is a generic concern whereas cockpits, propane locker locations and dodger designs are all unique. FWIW I''ve seen more than a few boats originally built in ''alcohol/kero'' days that added propane lockers in the middle of their cockpits to serve double duty as tables and a source of foot bracing. Perhaps the real issue is whether you are insured and, if so, how sticky your next surveyor will be.<g>
