I seem to recall a fellow that had a special built boat, he sailed from Oz, breaking a few records along the line, but the boat ran into some mechanical issues in the summer of 06, with the initial attempt at sailing this route solo. I am recalling him getting stuck with the mechanical issues on the east coast, with what would have been a late start, so he sold the boat, which was the intention upon completion.
So it has been thought of, and tried recently. If one had the right boat, this would be a fun attempt. Not that I would like it that cold.
She drives me boat,
I drives me dinghy!
