I AM LOOKING AT A 1982 CAT 22. IT HAS A POP TOP, BUT NOT THE SINK OPTION THAT SLIDES OUT? I LIKE THE IDEA OF ADDING PLYWOOD INTO THE CABIN AND MAKING IT A BIG BED FOR OVERNIGHTS. HAS ANYONE DONE THIS? ALSO THE INSIDE IS LIKE A ONE PIECE PLASTIC SHELL. IS THIS THE SAME AS ALL OF THE 22'S WITH OPTION UPGRADES? ALSO I WOULD LIKE TO PURCAHSE A TRAILER NEW OR USED AAND WOULD LIKE ONE DESIGNED FOR THE BOAT. i PLAN TO TRAILER TO THE KEYS, KEY BISCAYNE, AND SOME LOCAL LAKES ETC.. ITS THE SWING KEEL OPTION SO I CAN GET SHALLOW. I THINK THIS NEEDS TO BE KNOWN WHEN A TRAILER IS CONSIDERED. THANKS THIS SITE ROCKS!! BIG J
