They are not Skater hulls. And in your infinite wisdom HO Man, those Hydro Stream hulls were Renato Molinari hulls, and look up the Ferrari boat sometime. The hulls we use today are all spin offs of hulls that were used in the 1950s by early racing enthusiasts. Though there are serious alterations in many areas on all hulls from those of days gone by.
