FWIW,

Faced with the same problem, and wanting to minimize the number of holes to be drilled in the bulkhead, we simply used two appropriately sized woodscrews coming from the "back" side of the bulkhead and going into the photo's timber frame. The "back" side was in the head compartment, behind hanging towels, and so the heads of the screws were not a problem for us.

This solution seems structurally sound, costs nearly nothing, and does minimal damage to the boat.

Adhesive backed velcro or other attachments will likely slowly creep during hot wx, eventually failing as others have said above. I suspect that any adhesive that was man enough to last would do more damage upon removal than a few tiny screw holes which are not hard to repair.

Anyhow, I hope that you find an acceptable soulution for your application.

Cheers,
