Yes, if the problem is a lack of buoyancy to leeward then reducing the buoyancy is unlikely to help. I raced against a boat with this new hull shape in the early '90s; I think it's been scrapped, which is a significant issue with a 40 footer.

We know for a start that the BS force is strong with this one, since they claim to be the first doublehanded foiler. That ignores the Lugg/Smith (?) 14, the Rs from NZ, and the UK Cherubs. To ignore them either means ignorance or dishonesty.

Sorry to be so harsh, but I just don't get the idea behind launching a boat with so much fanfare before it's proven. It seems to be the equivalent of loudly claiming that you are going to win the worlds when you have no real track record in the class in question. 

Surfers sometimes say "if you can do it, it ain't braggin'" but the other side of that could be "do it before you brag".

Unconvinced by this hull shape, can't really see what a single bow adds.

As for names, mine appears on sailing related things everywhere, but I'm not sure how me being called Rupert or RJW66767 makes a difference to someone reading my post?

I agree the first post harks back to a boat from a while ago, so may only be obvious to people who were there. A fine opportunity for new people to assess the merits of the V2 for themselves.

The whole logic of merging the two hulls into a mono bow, was to do away with the lee hull trip and pitch which it did, I ran out of cash, well the tax man ran out of cash, before i could get foils on it, but I could see it evolving into something like that SYRA thing.. I don't think I've ever secreted my name, but the idea was to save folk who work for a living gettng caught out.

Phil Bolger used the analogy of imagining a hull moving through a sea of peas. I can’t imagine anything nice happening to the flow until the hulls go parallel. The design of a hydrofoil is not complex. Get it as light as possible so the foils have less work to do and can be smaller, secondly have a low drag hull so it goes fast before your use the foils to lift and again smaller. I don’t see that this design is light or low drag.

No Ian, my real name is Robert, not trying to be mysterious, I am Trebor on CVRDA, never used my real name on a forum, mainly because they have already been taken, even my full name of Robert Andrew Baker had been used on one.
Very difficult not to come across cliquey when you say something to a poster who you know in real life, or from sailing with them.

I am clearly out of touch with the correct manners on a forum. We are talking about recreational sailing and the norm seems to be that those posting dont use their name and dont make it available to other forum members on their account.

Am I missing something important?

I know iGRF's real name, but can't see it in the link you have provided, but can vaguely remember his various design ideas over the years, perhaps a link to posts regarding this design.

Sorry, thought it would be obvious that I was referring to iGRF. Most know his real name, but I don't like revealing other's real names on their behalf.

Mono-Cat



Looks like a hull that will work fine, once the foils have lifted it out of the water.

How iis it intended to work at low speed? Sailed heeled?
