I own a Orion, so you can tell my bias, the Dana is a little short on the water
line, if you plan any extended crossings that may be a factor. Both the Orion and the Norsea are 27 feet, waterlines are close enough not to be a factor for this conversation, the Norsea sails fine, but is tight in the cabin. The Orion has better engine access, really nice chart table, good tankage, main salon is larger, also has circumnavigated, and I have a goose neck trailer for mine, so it is also trailerable but is a major project with the permits for a wide load. But the real test is which one "boils" your water. All 3 are very fine boats and a guy could be very proud to own any one of them!!
Dats it from the 3rd coast!
