I get think of any that had no wood at all.. 88 and on Ranger and Winner where all glass except the floors , Transom Glass and stringers are glass .. but the floors and decks still wood.. which is still ok .. the only prob with a wood floor in the 80s and 90s was the drain holes in the cockpit floor .. they drilled the holes for drains and didnt seal the hole edges with epoxy or glass, and didn't glass the back side of the wood, only resin on the back side.. then rot over time would eventually rot out the floor around the drain holes, also didnt seal screws that bolt down hot foot seats etc so again another way for water to enter the wood.. and over time cause rot damage.
Now days the floors are made from a variety of materials Klegecell, Coosa Board, Fiberglass, and others .. the Mid 90s is when most boat manufactures started going all composite.. early versions where flaky.. lots of de-lamination issues.. by the late 90s and early 2000s most had worked out most of the issues .. Id still rather have a wood floor, the other materials in the early days where weak flimsy feel and if sealed properly a wood floor is as good as a composite as long as you seal any screw holes with epoxy..
Champion, Gambler, Allison, and Skeeter where also early adopters of Composite construction .. most of these didnt start till 96 or 97
Hope this helps and if you really want to know call the manufacturer if they still are around.. they should be able to tell you if a certain year and model was all composite or partially like the floors.
