Impressive. I don't keep propane on the boat so no worries for me.

I do have an older boat with the fuel locker as part of the boat interior. If the outboard fuel tank ever leaked, the gas would go straight for the bilge and make a nice fuel air bomb out of the boat. I've always imagined similar happening.

That's why I'm putting in a permanently mounted fuel tank. If it ever leaks it will be the same situation, but the new tank is much thicker than the cheap plastic tank I have now. Well, not so cheap but it looks cheap. That and the below deck tanks can vent which means they don't deform under pressure. My new outboard tank looks like a football. I know they are tested to pressure, but I just keep seeing it splitting at the seam one day.

I have some 16oz butane canisters that I keep on board during the sailing season for my Burton Stove.
It works great for burgers, eggs and fish fries in the frying pan.
Now looking at this, I'm scared shirtless to keep any open tanks onboard.
I've also had a sealed canister start to rust - meaning had I not found it and used it immediately, it would have filled the cabin with gas and KA-BOOM!!!!
All it takes is a 12 VDC switch opening to create a tiny spark. I think I will create a box for inside my gas locker to store the canisters. I never even want to get close to a problem with propane, butane or even octane!

Bruce: 16 oz, or 8?? (I assume you mean 8.) How about the "rope locker" on starboard--sealed from below with no ignition source?

You point out an important issue: Butane canisters are like spray-paint cans. Watch for rust around the rims and err on the side of early replacement. It's worth the $4-5, as illustrated in the video. (Yes, the boat was still floating, but the "occupant" was in the water some distance from it, probably unconscious.)

You're right Dave, 8oz. Still deadly as a hand grenade! The rope locker will do. Now I keep them is ziplock bags but condensation can rust out these canisters, albeit a lot slower than humid sea-air.

crash test is great. I love the jury rig tryout, and the self righting test.

Some time ago, there was a post that showed a canister holder that fit on the catbird rails.

It was basically a 3" or 4" (not sure of the diameter) PVC Pipe, about 2' long, the lower end capped off, the top end had a screwed on 'lid'. It was mounted on the catbird seat rails outboard.

It most likely had a drain hole in the lower cap. Not sure how the canisters were extracted from the top opening (perhaps a line attached to a movable ball below the canisters)

Because we take JD out on 3 to 5 days mostly, we keep at least 3 cooker gas canisters on board and 2 grill canisters on board.
