My understanding is that Paul Lindenburg designed the hull for Warren Luhrs distance racer, and then Cherubini, who was sort of the in house designer, designed the modifications from the original raceboat design such as the deck plan, interior,
rig and keel. I got that second hand at a boat show when these were new boats, but then again its a long time ago and I have never followed it up, so it could be wrong.
