back again,
i used a two part epoxy paste to attach my 3x4x3/4 inch wood blocks to the openings i had cut in the cloth covering to the inside hull in the cabin. once set i screwed the rod racks securely to the blocks then placed four rods. it seems to be very strong and looks good.
if all holds up i will install another set on the starboard cabin side. we have a few other things we plan to install in the cabin and this method is easy and seems to work well.
eventually i will take some pictures and post them.
