There are quite a bit of new boats in this cycle, but not so much "brand new design/molds", Paul Meilhat was talking of "new old boats" in last tip & shaft podcast.
Btw his new boat launching video :
Typically, only the new Charal and Malizia (not even sure for Malizia) are from new molds, otherwise :
Biotherm : same mold as current Advens (Thomas Ruyant)
Initiatives Coeur (Sam) : same mold as current Bureau vallée (ex l'occitane)
PRB/holcim : already built hull, same mold as IIth hour ?
Maitre coq (Bestaven) : same mold as 11th hour

But the new Apivia and T Ruyant boat will be brand new designs from what I understand.

(but then again, the hull is far from being the only thing in a new boat. But let's see how the "next together" Charal rudders will perform for foiling stabilisation, the only major innovation in this cycle somehow, up till now)

If you were a betting man you'd have money on Charlie being able to win the next VG with his current boat. And if you are that same betting man you'd have money on Charlie being able to win the next VG with his new boat.! :LOL:

I'm not sure if Kevin's PRB/Holcim hull is from the exact same mould as 11th Hour. They're both Verdier designs but Kevin's was built by Jason Caroll in the UK, originally supposed to be for 'Team Slingshot' TOR campaign that got canned.

Its also had a new bow since it was originally built so even if it was out the mould its slightly different

When did SeaExplorer meet LinkedOut and Apivia on the water? Did the latter 2 come back from a race?


Great video. I gather they had some electronic issues and not sure how they ended up fairing against the other boats. Their coach roof seems to be practical. Looked quite cozy inside.

But at the end when high on the foils, he has the windward rudder lifted, so not clear if they want to use it as a rear "foil" or not, maybe for a further step...
Angle of leeward rudder is designed around flight control of the back of the boat, so windward rudder can be "classically" lifted and protected.

leeward rudder is more just "rudder" foiling or not, you still need one :)
Correct, you still need to steer the boat. But if you can sacrifice 10% of effective steering to gain 5% of lift, and safely design around it, you might change the structure and nature of the boat and risk the rules to put the rudders in the middle.

See VO70 angled daggerboards (although not a moving appendage), with an acceptable leeway % penalty to gain a % of lift with a straight board.

But the point (which has been discussed around), of having the two rudders so close is the possibility to use the windward rudder for flight control, don't think the leeward one has much lift when healed. Whereas the "classical" rudders positions clearly would not allow that.

And if the plan was to lift the windward rudder as "usual", then having it so close to the boat center appears as a disadvantage : much more exposed to the sea.
