Arnis Zvirbulis on a Hobie 20 somehow trashed two mainsails and broke a daggerboard, and I don't think he ever got farther than Angelfish Creek. The circumstances are still unclear. Apparently, he returned to Gilbert's soon after the start because his mainsail was coming apart. He replaced it with another mainsail, exchanged battens and set out again. I'm not sure how far he got before the second mainsail started coming apart, so he again returned to Gilbert's and called it a day. I don't know how the daggerboard broke.
He said he will be back next year, though, with a better sail.
