There are several Great boats for voyageing. I guess it comes down to what the indivual likes. For me that would be Pacific Seacraft. But just so I am not killed here there are many others just as sea worthy and liveable. The size depends on how many in your crew. I have heard of voyagers heading out in a 26 footer on a 2 year or so trip. I wouldn''t do it in anything smaller than a 34. That in my 2 cents worth and it''s worth about that too.
