I watched the sailing tracks for all the boats. One Multi turned back BTW due to broken mast. Gunboat 66.

The multi pictured in the post by Phil actually went a much longer track than rhumbline... choosing to reach vice DDW on their "final" gybe to the islands... and yet they still beat the fleet, even after starting a week later. Pretty darn fast on a boat actually. While they may have averaged 17kts, the often exceeded 20. That is flying low folks!
