Most of what I can find on-line for gas standards applies to propane lockers, and doesn't apply to stern rail configurations. I'd like to make sure everyhing is as safe and well thought out as possible. With that in mind I have a few questions I'd appreciate hearing "best practices" on...
- What is the right way to have a flexible gas hose exit the fiberglass (to reach the external tank) and be protected from chafe? I've seen lots of wire "glands", but it seems like they would (1) be too small for a gas line, and (2) I don't want to compress the line, do I? Those glands are water tight by compression.
Get a bulkhead gas-proof fitting for the gas line. This will be much better and easier to maintain. They look like this:

- Is there any special type of hose or fittings or treatment I need to consider for the gas line as it is exposed to the elements vs. always being protected in a locker? My current hose is showing some signs of UV damage (drying out), although minimal. Note that I am in fresh water, although future brief salt water is a dream.[/quote]
Fit some cable loom over the gas line where it is exposed. This will protect it from chafe and UV damage.
- I'm assuming I don't need to use a electronic gas relay / valve with the tank on the rail since I just use the manual valve for on/off. Is this right?[/quote]
Don't need to have a gas relay/solenoid setup, though having one with a gas alarm is a good idea on a boat. Getting the gas alarm by itself would be a wise idea. This one can be used as just an alarm, but does have a switch for a solenoid if you decide to add one later.

- Any other "gas on the rail" best practices you can share would be appreciated. I'm ripping it out now and will be replacing it soon, so all design recommendations are appreciated.
Thank you in advance,

You can easily achieve the same purpose by leaving the burner going and then going out to shut the main gas valve off and then coming back in to shut off the burner. Not quite as convenient, but does end up with the same result, and its what I do on my boat. The tank valve is shut off unless I'm actually about to use the stove.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
