Been through there in much worse. One trip on a 39' custom, we tore the wind instruments off the top of the mast! Went down to Hadley's to lick our wounds and get the instruments untangled from the backstay. Standing waves that day must have been at least 6'. We finally had to bear off and take them at an angle, tacking our way out into Buzzards Bay - tacking to the waves, not the wind.
