Re: Full or fin keel?
Don't see anything about CFD Paulo. How are you certain CFD was used? Can you provide a CFD study that has been published? I'd like to see that for my own education. I wouldn't make the automatic assumption that CFD is being used for every new keel you see from a major design office.
I understand the theory behind the tandem keel. As I said it is far from a new keel geometry. I don't doubt that it works, to some degree. But the real appeal may be more for marketing. Seems like you bought it.
I don't know of any major NA cabinet that does not use CFD in what regards hull, keel and rudder design.
I am not defending tandem keels against other solutions for swallow draft. I am only saying that it is still a contemporary solution in a sense that it continues to be a valuable option.
Personally I think that the best contemporary solution for a shallow draft are swinging keels. Those are the only ones that manage the miracle of offering a similar tracking upwind, a slightly lower weight for the same RM at the cost of a slightly bigger draft without having a big intrusion on the interior habitability. The only real problem is that they increase the boat price and need some maintenance.
