gas storage
boudewijn
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 enginedash since I suspect that is
"electric cables within 200 mm of the gasline".

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.

just placed a single gaslocker. Starboard at the helm. The Inno Nautic
pre-fabricated one http://www.edt-info.com/inno/2_a.html
Did not connect the bottom vent yet. I see the difficulty of avoiding an
upslope 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
upslope for the bottom vent is allowable.
