folks do it all the time... I have seen tons of catamarans in the open ocean over the years.
Of course you have; why you're Popeye the sailor man dontchyaknow.
A couple of things; (1) a Catamaran is the single worst vessel for open water ocean passage; (2) a 35 foot boat is extremely small for an Atlantic passage, especially a catamaran; and (3) I seldom believe anything that moron says because he is a dishonest asshole and I doubt he is capable of sailing anything beyond the little toy ducky he keeps in his bathtub.
Now you can believe it all you want because you're the BIG sailor man and a gullible dunce. ::wink wink::
