Doing some brand research on construction methods as part of my used-boat shopping and wondering if anyone knows when Four Winns converted entirely to wood-free boats. In particular, does anyone have or know of the Horizon 170 or 180 bowriders, 1999 and beyond, still having any wood in the stringers below the fiberglass/gelcoated deck? Or in the transom? Are newer Four Winns fiberglass decks/stringers/transom susseptable to stress cracks or spider cracks?
