I pretty much figured out they build the insides from the stern forward on Catalinas, and I had to remove the decorative bulkhead just forward of my galley to get the old top out. But on a C30 look for screws behind the settee cushions that will be holding it in also, they used a lot of machine screws from above, below, and on the sides, and not necessarily in the same place on each boat, as apparently each worker assembling had their own ideas of where screws should go. I removed all the old countertop and built an entirely new one. This is a very good time to redesign the galley if you are so inclined. I moved location of sink faucet, removed stove and made that whole area countertop w/storage underneath.
