Bill says this is the "best longboard" he's ever designed. Historically, the Hydro Hull has been Bill's top-selling board worldwide. This next-generation Hydro Hull has a modern trim rocker with a single to double concave bottom and is made with Surftech's proprietary Tuflite V-Tech construction process. These features are complemented by a beveled entry rail, which provides forgiveness as well as performance. The 2 1 fin configuration is another proven Bill Stewart innovation that's stood the test of time. The New Hydro Hull is the all-purpose surfboard for those seeking more waves, more fun and more performance.
