Or at least 60' IMOCA compliant ones. They seem more robust that the canting keel foilers, and higher volume hulls would be less affected by having a crew aboard. The 40'ers proved to be in the same league as the IMOCAs in the RdR, a 60' version would have to be faster than many older generation...
Real shame. It was the only boat that had me really motivated to visit the docks this year - I haven't been for a post race dock walk for the first time in over a decade.
