O27 suggestions for reinforcing the stanchion backing plates?

[JonnyQuest]

My stanchions for the life lines are pretty are anchored pretty weakly, and any lateral pressure causes significant flex of the decking fiberglass. I can just see someone accidentally putting too much pressure against a lifeline or stanchion and ripping it out of the decking. (like the kids!)

What would be a good piece of backing plate to use? Plywood/marine plywood/steel/etc? Any sort of gasket between the backing plate and the underside of the deck such as a rubber sheet or simply a ton of caulking?

Any pointers would be appreciated for this project, thanks!

It would take to long to type out and everytime I type something long, something else happens and I loose the post. So, Click my Avatar, sent me an e-mail and I will give you my phone # or you give me yours and I will explain it over the phone. I am sure it is posted because I wrote it up probably 5 or 6 years ago but it my not have made the transition when this web site changed changed operating systems.
