The very botom of the hulls are nearly identical, they added a bit more "swoop" to the 278 but wetted surface is the same, I'm pretty sure. The oval shaped port lites on the 278 do make it look like a different hull. I remember when the 278 came out a few years ago at the boat show, the salesmen said it was basically a re-badged 268.

As for C. Raymond Hunt, this is from their website.
Quote:
Four Winns approached C. Raymond Hunt Associates for a complete package of hull, deck, interior and structure which became the 378 Vista. The 378 Vista, regarded as the best-running Four Winns ever, led to the design of a second Vista, the 358. We provided a new hull design for the 358 Vista and the hull and structure design for the flagship of the Four Winns Vista line, the 458.
