With the utmost respect to GordMay, given what you want to do, of the boats you mention, the Cheoy Lee Ketch
would be my choice for you.
The term "Seaworthy" has many definitions and if you put the boats you are interested in against a "Seaworthy Scale" of some kind, possibly by asking questions in forums
such as this, I have absolutely no doubt that the Cheoy would win hands down.
And, again, with the greatest respect to GordMay, in my more than 50 years of global sailing, I have crossed the Atlantic many times, mostly single
handed, the first time with a C&C
25 footer and I will happily tell you that although I survived to tell the tale, no amount of money
would induce me to do that round trip in a 25' again.
Let me put it another way, when you are out there, even within 50 miles of a friendly shore, when a major storm comes up out of nowhere, you will ask yourself(Just as we all do) "Why the hell didn't I get a bigger, stronger boat".
But that's just my opinion...James
