The Magnum Missle was a copy of the Austrian racing champ and boatbuilder, Dieter Schulze. Don bought a 16' and a 19' and copied both of them. After we sold Donzi to the Chisholms, I worked the 1968 Miami Boat Show for Don selling the 16' missle. The demo boat had a 135 Merc, and ran 65 mph. It would make a 30' circle at that speed. Anyone with an underwear concession at the dock would have made a fortune, if you get my drift.
