I think beneteau dropped the smaller center cockpits....Tartan is like Sabre a few steps up both in quality and comfort. My 1983 Sabre 38 is much more boat than the 1999 36CC I used to own, and for a third the money. You may look at an older Tartan/Sabre. Hanse is almost too new to really know. Bavaria is real nice and priced right, but may not have the quality over the years to hold up as well as the others.
The Hanse, Bavaria, and Beneteau will need considerable add ons to truly be ocean crossers.
All the best.
