Blue water cruising boats
Xnavy, I''d encourage you to add Hallberg-Rassy to your list. To ''watch'' a well-built boat being constructed, visit their website. Examples of what I''d like to see other builders emulate are fully laminating together the hull & deck fully (no leaks), imbedding stubs in the layup for the stanchions (no penetrations), and then grinding smooth and painting the entire inside before anything is installed. This means everything built into the boat came thru the companionway...and can come out the same way.
Suggest you keep in mind that there are many views on what a ''bluewater boat'' might be - your list could almost be infinite - and that you''ll pay far more in some cases for that last 10% of capability that you may never use.
