Aerodynamics of a racing yacht

[Jackdaw]

This might appeal to only the engineering-centric sailors here, but this is a slideshow that describes the state of play in the use of performance modeling software to design modern yachts. It makes interesting viewing even if parts make your head hurt. This is the level designers have to play at if that are going to create a winning boat. The the big guys JuanK, Finot, Farr, etc do this.

Jackdaw - Thanks for posting this. It's great application of modern technology (CFD and RANS) to an arguably ancient problem - how to make a sailing ship go faster and point higher. Figures 11 and 12 in the attached open access paper are interesting to ponder for fractional rigs. And yes - some sections will make your head hurt more than a little bit... Dan

That's very cool, thanks for sharing that. It's been clear that while CFD has been a boon for hull and underwater appendage design, its use in the sailplan has been hampered by its inability to deal with real-world un-niceties like the mast, deformation and other attributes that mess up a pretty little model. Neat to see someone trying to correlate real measurements against model predicted values. Onward.
