The DiMarco hull was a splash of a 20' Spectra, but Sonny did a few minor changes to the deck. At the rear it is rolled rather than stepped like the Spectra and all around the gunnel at the deck there is a nice rolled recess, really looks good. In 1976 the Spectra that was used for the splash was still in Sonny's yard. Really nice boats and well built. I can't compare to Raysoncraft as I have never been in one or owned one. Probably doesn't ride as well as a Schiada as it has less deadrise.
This mold was later sold to Kurtis Boats and then to Canyon.
