I have often said that some boat manufacturers could take lessons from RV manufacturers regarding ergonomics. Like our friends, Herb and Wilma (Willie's Tug), we just came off 6 months aboard our boat. While the cockpit is good for some folding chairs, in the cabin, most of us are limited to the dinette for seating. Those dinettes are designed as another "sleeping area," making the dimensions somewhat fixed to be used as a berth. I would suggest that most of us don't have overnight guests... give us a comfortable place to sit in the cabin! Barrel chairs with a small table between them could be an option.
Years ago, Born Free Motorhomes began to offer a Class B model called "Built For Two." They recognized that not everyone wants or needs space to sleep a family of 12 (yes, I'm exaggerating... just a bit). Design an interior for the comfort of a COUPLE.
Ranger Tugs does a better job with this than C-Dory (our boat), but offering something besides a dinette configuration could reward manufacturers as more people retire and start looking for "an adventure." As a couple.
I think the R-27 is an ideal couple's boat, especially if you intend to trailer. It is obviously a sales success for Ranger. I understand the desire to not mess with a formula that works. An interesting design challenge/opportunity for the Ranger design folks.
Best wishes,
