I have a friend.....
that use to make that trip in a 23 footer every year for several years in a row. Then, the last trip was a breaker, he and two crew members survived a storm that lasted 12 hours with 15-18 foot waves crashing all around them. He said the ocean was just white foam and when the boat would climb a wave it would barely make it to the top, then almost as if someone jerked the floor out from under you, it would fall into the middle of the backside of the wave and felt like the boat would break in half. He picked bad weather to begin with which was asking for trouble, but, his boat survived as where a 45 footer sank in that same storm. So, maybe size has less to do with it than skill and luck.Pick good weather and have good sailing skills to get you there alive, oh, and good luck.
