You are right, Wouter, you are not a real designer. You are a buyer and a user and a talk abouter. Back in the 1970s and early 1980s when I was doing my basic beach cat design/study work, there were no GPSs. What would you suggest I do; wait until the 1990s to gain understanding about the design and performance of beach cats using a GPS? The last clean sheet design I did on a beach cat was 1979, the RC27, winner of the Bol De Or race in 1989.
Dream on, Wouter.
