So the Volvo Ocean Race got nearly twice the number of viewers than Euro 2012 Soccer champs (2.9 million vs 1.5 million).......is this just the usual spurious ways of presenting data, or are we really expected to believe that?!
Fantastic looking boat and Lemonchois is I believe one of the best long distance skippers. However I'm beginning to have my doubts about wave piercing bows!
Rémi Laval-Jeantet, PhD former Alinghi's consultant in hydrodynamics : > To be a cat's sailor means compulsory to be a former pitchpoler. The opposed area of wings in rear winds during bear away manoeuvers already ruined our effort with the C-Class OTIP in 1990 and this had to happen over the ACs 72. ORACLE 17 also shows a fundamental error in her foil configuration. To be stable in ride height without a wand or an altitude sensor, can only happen on an hydrofoil boat if you have a surface-piercing V front foils like "L'Hydroptère" or the famous "ICARUS". TNZ has designed an "S top" for the daggerboard which allows it > i.e an "half-V" foil with a 22° dihedral angle which pierces the free surface and guarantees level stability (not an absolute warrantee, but sufficiently robust). ORACLE was suffering from erratic pitch departures and was fundamentally unstable in pitch and heave, flight mechanichally speaking. RLJ
So I think we must be rapidly coming to the conclusion that wingsails, while profoundly cool technology, are perhaps too risky (and costly) to be used on boats this big? Interesting that the pitchpole occurred during a bear-away, not in a foiling-related incident.
If you are planning on setting a new Jules Verne record for sailing around the planet. Make sure you take Sicomin resin for any emergency repairs - see about 6 minutes in...Highest respect to the team here for an astonishing feat!
Why not call Matrix Composites, even if you only intend sailing around Hayling Island!
