Gas storage


by the way, was it your boat that I saw a picture of, from the mast down, showing two circles in the cockpit, close to the shaft of the helm? Is that for gasbottles? One running, one spare? Maybe even the prefabricated ones from Inno-Nautic?
Nifty place, I think I am going to check if that works for me and copy that.
I would theoretical need to move the engine dash since I suspect that is “electric cables within 200  mm of the gasline”.

    Yes… two gas cylinder lockers, one for in-use and other for spare.
    They have a drain pipe from the bottom to a vent through a non-return valve and out through the hull just above the waterline. Snag is the vent pipe has a low point so water collects in it and this would stop gas venting. [My surveyor picked this up.] So I have run second vent pipes from nearer the top of each locker. Theory is water drains through the bottom one and any gas building up in the locker through the upper pipe – both joining to out through the hull.

    I sailed a boat in New Zealand that had a solenoid valve operated by a switch next to the cooker, so the gas was only on when needed. I liked that. But the solenoid-operated valves I have found would not fit inside my gas locker (very limited space), and putting one elsewhere where any leakage would find its way into the bilge defeats the purpose. So I have contented myself with installing a gas alarm instead.

    Hi Tony,
    just placed a single gaslocker. Starboard at the helm. The Inno Nautic pre-fabricated one Did not connect the bottom vent yet. I see the difficulty of avoiding an up slope and keeping the through hull fitting accessible.

    Surprisingly the lid is gas (and water) tight, with a compressed “O”-ring. Which means the locker may contain gas upon leakage, untill it diffuses out through the (so short is of th essence) 20 mm bottom vent, rather then by gas density difference.

    The thing is certified. The reasoning must be, the locker atmosphere is allowed to be potentially explosive, since there is no ignition source inside. So an up slope for the bottom vent is allowable.

    regards Boudewijn
