First movie with by yacht.de that had already tested the boat. The movie is very interesting not only because it is the first and because they give a good view of the boat but also because they tested at the same time a version with a standard keel and a version with the new swing keel version. The performance does not seem to be very different and that is just great.
Here is the link:
Eric De Smedt - SWING KEEL PERFORMANCE
I expected that, even with a similar centre of gravity, the swinging keel would perform at least a litlle better because of its higher aspect ratio?
If I understood rightly the new swing keel will have 2.54M while fully deployed and the standard keel will have 1.98M. I believe they are designed to provide the same righting moment. I don't have enough data on the new keel but it is possible that the weight of the keels are similar, maybe even the swing keel a bit lighter. The drag of the fixed keel will be smaller but the grip of the swing keel upwind should be marginally better, as you say, due to a bigger draft. Maybe you are right and not only it matches the performance of the standard one as it can improve a bit the angle upwind and that can be a better performance improvement than the loss due to a slightly bigger drag in all other sailing positions.
They do not mention it on the video (and the performance of both boats seem very similar) but as Anders reads the magazine I count on him to post about what they say regarding that on the test boat article.;-)
I don't know if they are going to make a deep draft performance version of that boat, I would say a torpedo keel between 2,15 and 2,30m. A keel like that should have a marginally better performance than the swing keel. Regarding the standard one with 1.98M, I think that if not better the swing keel is certainly not worse.
