I day sailed a 42. It was an early 1980's boat
. It was shot. Still good for day sailing
but it's better days were behind her and in a storm that boat would be a fright. At this point I would say it's not the brand but the mileage. In great physical condition under favorable weather
it would be easy. It's when each becomes a little bit less that the situation changes quickly. These boats were never designed for ocean crossings so forcing the issue is more than the designer
ever expected. Most of these boats were never intended for that purpose because most of the owners never wanted to do it. It's not so much that neither could but that neither intended on doing it.
The Atlantic has been crossed in a 9 ft boat but I wouldn't do it myself. Just because something has been done is not always the reason you could do it too.
