First notes and elements (to be refined...)
This boat is one of the six (?) sister-ships built in a row in Australia off the same mould, I guess between about 1991 to 1992 (?) : AUS-052 "Arunga X" to Franck Tolhurst, AUS-054 "Sic Em Rex" to Colin Ryan, BAH-014 "John B VIII" to Robert Symonette, FIN-037 "Carmen" to Vladimir Marschan, GBR-038 "Salamander IV" to Jonathan Janson and GER-024 "Lovana II" to Hans-Juergen Queisser.
I remember Colin Ryan presenting the project in 1991 at Le Crouesty (FRA) european's. None of the boats were present there yet, but at the worlds 1992 in Nassau, Bahamas, all were participating except FIN-037 "Carmen".
In August 1992, we have been consulted to analyse the design and to propose eventual rooms for performances improvement. Pointed-out troubles were essentially located in the bulbed keel - too much pitching and lower aspect ratio of the fin - and in the excess of flare (very wide beam at deck) which induced shorter and deformed waterlines at heel. Sorry Iain, Bobby asked us to provide a frank and free eye, and this was only our opinion at this time. Other ones to be expressed ?
