I would expect the horizontal chain link material to sag between the horizontal crossbar supports. If not right away, then over time as the hulls slide in and out.

So the bulk of the hull weight would be on the intermediate support bars, not widely distributed on the chain mesh.

If the horizontal bars are omitted and the chain link fencing is installed like a hammock (supported down the long sides) then it would hopefully sag in a controlled manner and evenly support the hull weight along the full length.

Or use some sort of tough fabric to create the hammocks, not fencing. Something that would air dry and not have too much sliding friction.

I just occurred to me that plastic 'construction' fencing might be suitable. See photo...
