Use Lined metal ones then get your self some closed cell foam put the foam between the drums and what you are lashing them to to stop rubbing,at least then when the time comes to use the fuel it will be there.
Have you thought of fuel bladders? you can have them made to order, you can even tow them behind. The military use them . You just have a fitting made to suit a small electric pump
for evacuation of the fuel , when they are empty you can lay them on the floor if space is an issue. Where are you? ie Country?
Checking them out now. In the US, where I am, it looks like they're available at this site: https://readycontainment.com/store-2...=0&sort=normal
When full, I would guess they'd be hard to move, i.e. in dinghy
from to shore to boat. Have to find a good storage
location (would you dare store them in a locker, probably not). Can't imagine having to deal with the rupture of a 20 gallon bladder.
