Holding down the gas can?

[bhackford]

How should outboard gas can be secured? I heard they should not be?

Always kept mine in a vented above-deck locker. Not strapped down, but definitely confined in place. And the locker made a good seat.

I've never strapped one down. Figure if you have a fire onboard you can grab the can and toss it overboard.

[Plover]

I think to just aluminium angle or small strips of wood scewed down to keep it from sliding about would do the trick, unless its in such a place that it can be lost over board.

Best to install in an accessable location. Can use a nylon tie down strap, with 3/4" contoured blocks/ chocks, to keep from slipping around.

seem pretty quick to answer your own ?

[Thorne]

Always used bungees when necessary. Never heard anything about not securing 'em...

[Figment]

I've always strapped or tied or bungeed or otherwise appropriately secured them. Less tank movement equals less wear & tear on the fuel line and fittings, less potential headache is a good thing in my book.

Short answer: Why not?
