The pictures with the decks removed were from a Nacra 5.2. I have a 83 Nacra 5.2 that I removed the decks on for repairs. I used a chisel to get under the lip of the deck and then used a large knife and gasket scraper to get to the middle of the deck. If you have remove the rear deck, there will be a lot of resin around the daggerwell to break loose if your boat has them. Make sure Performance has decks for your boat. I still haven't heard if they found the molds for my 5.2 decks. I have found a used deck to install on mine though.
