Chris, I hadn't heard the info about these being lighter in weight, interesting info. If that's the case they would also have been faster if the weight reduction is significant.
This appears to be an "aerodynamic" styling technique that was applied to the Commander and the Catalina boats, while Roamer had the swoopy style all along to some degree and didn't change much. The interiors of these "swoopy" design Commanders don't appeal to me because they're all white and finished with wall paper or plastic laminate, and it's a not as handsome as real mahogany. It is, however, brighter inside, something we've tried to accomplish with lights and mini blinds that open totally.
I don't dislike these boats, but I'd rather say I prefer the older style that looks more along traditional lines.
Interesting find!
Paul
