I don't know of any actual designer with that notion.Never say never, not that I disagree with your analysis, but I guess the notion originated with the designers.
Totally different: Moth is single central foil:I wouldn't rule it out-the Moth tacks on foils even though the crew is a major drag. Every time anyone has categorically said something was impossible in the history of foiler development-it's been done.
The boat likes to keep some forward momentum through the turn.tacking on a cat means each of the hulls have a different speed and therefore lift during the tack. You are turning the outer hull somehow around the inner hull. Hullspeed is close to zero in the turning point.
Is that true?
With respect, given the weight (momentum) of the boat, there's simply too much drag (wind on the nose, foils and rudders in the water) in such a large turn. And it's a pretty pointless debate, since time will tell. Just place your bet.Foiling tacks are a challenge, but not an impossibility.
The big technical item that could potentially enable foiling tacks is how fast they can turn.
With both daggers down, the boat foiling but low low and held flat, it can turn very very fast without much loss of speed.
The biggest challenge would probably be amount of control required.
A significant concern could end up being how to keep the crew on the boat as it does the High G turn.
