the above is not to bash any builder, but just to illuminate the various issues.
As for Blue Water sailing - a buddy of mine sailed for 5 days and nights delivering his Santana 20. It was just him in his 20s and a teenager. They left Marblehead MA for NJ, they decided to sail around Cape Cod and outside LI. The winds never dropped below 25 knts, and were mostly 30+. They and the boat did just fine.
A Santana 20 was built for around the buoy racing
