Adventure 218

21' WALKAROUND CABIN

Grady-White’s Adventure 218, a go-anywhere, do-it-all, reimagined version of the original walkaround cabin design. The 218 is sleek and stylish, built on Grady’s heritage of superior performance, exceptional quality, seaworthy-safety, and versatility. Designed for both the devoted angler and families that fish, play, and overnight, the 218’s wider beam provides a more spacious walkaround and cabin. The addition of integrated swim platforms and pivoting aft seat backs affords more room for the angler to fight fish while also providing easy access for watersports. The curved windshield and signature sheerline yield an updated profile that adds to this boat’s head-turning appeal. Get your new RV for the water today – the Adventure 218!
