E.G. Foil size and shape to allow an appropriate "take off" speed
Did I see another crew inside the hatch - whats he doing, monitoring the elements of the craft or foil angle control etc
Did I notice some aluminium on the boat or is it all carbon
Have they down sized anything for the Pacific Ocean run?
Do they need crew to have personal intercoms or is sign language needed at that speed
I have been on an ORMA 60 and noticed the French step up a bit different, why do they have the winches etc in
those positions on the boat?, and whats with the steering wheel?
Why so small floats, wouldn't bigger floats help them in lighter wind.
No center board?, how much sideways movement do they get when the wind in on the beam and forward of the beam
I could go on, but I'll let others include questions to this list.

a ) wanted twin T rudders for better stability control and avoid pitch-poling.
b ) better handling in wind too light to take off and/or big waves.
c ) better weight distribution closer to the foils allows for lighter construction.
d ) other.
e ) all of it.

Does this generate pitching? And how well is it dampened by the Rudder-foil?
In other words: Is there a waveheight-limit?

I see they are taking a crew of 5. How many people are needed on deck to run the boat?
Posted 16 July 2012 - 03:06 PM
How will they handle watches
How will they rest when it seems to be an "all hands on deck" continually?
How long does it take to be a competent "helmsman" - meaning at night, no horizon, big squall work
How to mentally handle the possibility of a "trip over" crash. No chase boat can keep up, just rely on the merchant marine?(I'm not implying a negative here, just asking)
And will you be sending out daily logs/stories of how its going?

How much time do they have sailing at night?
What are the loads like on the boat (helm, sail controls, foils)?

i would like to ask Alain one thing : Can i hitch a ride?

1. What changes have been made to L'Hydroptere DCNS to prevent pitchpoling in the Pacific?
2. I am familiar with the history back to1976. The design has always had a lifting foil rudder on the stern. Did Alain ever consider a canard configuration with a lifting foil rudder at the bow?
Congratulations on a great effort! (I started a similar project in 1970, but was limited by funding and never went beyond a first sailing prototype.)

Just listened to the whole interview. Alain Thebault was hesitant to answer some questions-keeping more secrets than I thought they would. Both guys have heavy French accents which I have trouble understanding. I took notes and it is surprising how few they are for such a long interview:
1) 44 knots(50.6mph!) peak in San Fran Bay,
2) Do well upwind in 3M waves,
3) Won't tell about pitch stability "secrets" or any details of the new electronic pitch control system,
4) Alain wants to go for "the 65 knot barrier:,
5) They can change the angle of incidence of the main foils after stopping but not underway,
6) Forward looking radar.sonar an ongoing project-not working too well at present,
7) 2 or 3 on deck in conditions under 30 knots boat speed,
8) Steering very intensive-no autopilot-keeping laminar flow on the foils is main task of helmasman who can't see the foils so has to learn this by "feel".No "feel"(feedback) in the steering system at all.
9) Best angle upwind 90-100 degrees but can be improved by flying the windward foil.
10) Alain still working on design of the new "round the world " version-should be complete in a few monts. Need an additional sponsor
