The method to hang the table from the bulkhead with legs underneath doesn't work on my boat - 27 Cat. I'm thinking of purchasing a pedestal to hold the table up, however before I start drilling holes through the area the pedestal will sit on, what is underneath there?On my dinette model with galley towards the port bulkhead, across from the dinette, the area underneath the table is a raised platform that appears to be totally enclosed. Is the area filled with foam, or just enclosed "dead" area, or what? Will it be safe to put a pedastal on this platform?
