Need advice with replacing cooler mounts.

[cdlong]

The cooler mounts are the umpteenth set I've broken. The location is a PITA, but that's where momma want it. Plenty of room for chairs when the kids and Grandkids come along. (They haven't come along in years) & for fighting fish. (Too much Wicked Tuna on her part). Anyhow, I'm the bull in the china shop. Seems every time I work on the boat, I break one or two of them. Ya'll have suggestions for a different type holder/ mount? I assume I need metal?
Thanks for your help.
