This couple pulled it off, after their Sweden 390 EGRET lost their rudder on the same passage a few years ago... Seems the prospect of abandoning her never even would have crossed their minds... They lost steerage 1500 miles out from Martinique, yet still managed to complete their 2200 mile passage in just 26 days...
Pretty interesting read, this is a link to a PDF file of their account...
