Of course there is hydrogen in air! (It's been a long day!)

I don't understand what you're saying...

I meant that Zeppelin airships used hydrogen as it's much lighter than air. Helium used more commonly, as hydrogen very combustible - there was a huge airship disaster many years ago, the Graff Spee if I remember correctly.

Edit - The Hindenburg, not the Graff Spee!

The graf spee was some big ass german battle ship wasn't it?

My fuel tank will be in my console, so I guess venting is a good idea?

Certainly was! I don't think there was much chance of it getting airbourne
If your fuel tank's in the console, then I reckon that you definitely need a vent. Incidentally, we keep a tank of 2-stroke in a non-vented locker (it's safe as there's no electrical apparatus in there) but managed to make a passenger seasick a few weeks ago by just opening it whilst bobbing around in big swell. Oops, sorry!

Is water heavier than Air. High up is good but if you really want to be double safe then point the Vents back toward the stern,

Have you fitted many consoles Richard?

Why is that relevant? The thread is about whether to put a vent in a console!

I've got my fuel tank in the Jockey console and there is evidence that the battery was once fitted in there as well. I have no vents! And the switches and fuses and everything is in there . I guess my RIB is over 10 years old and hasn't blown up yet!
