Castoff, I owned and cruised a Rob Roy 23 for four years in
San Diego and Mobile Bay. She was a great boat; the modified sharpie
hull has rounder bilges than the Nimble boats and didn't pound all that much in rougher waters. She also has a tad more
interior room than the Nimble 20 (which is pretty much the same boat; Ted Brewer designed both, the RR first and then the Nimble after he parted ways with the RR's builder) due to the RR's
centerboard trunk being below the
cabin sole.
As much as I loved the RR, though, I couldn't recommend her as a
live-aboard or longer term cruiser, the
storage space was too limited. We once packed her for a 10-day
cruise from Mobile to Lake Pontchartrain and she was full beyond the limit, it was like a Chinese puzzle every night, moving stuff off the bunks and into the
cockpit to be able to sleep. And the "sitting room only" of the RR
cabin got old after a few days, although that can be a personal preference (as Uffa Fox said, "If you want to stand up, go on deck").
After the Pontchartrain
experience (and we never got there; the
rudder stock parted our first night out, a weak point of the RR design; we sailed the boat over 30 miles home
steering with just the
sails, a strong point of the RR design) we decided to move up to a larger boat and bought our
current 32' Lazyjack schooner.
The Rob Roy was terrific for daysailing and weekending but as you say, was more "camping in" particularly as compared to our
current boat which we've spent upwards of a month at a time on with no problems.
There's at least one Rob Roy currently for
sale, listed on the sailingtexas.com website, if you are still interested (although I gather from your postings above that you've also concluded the RR and Nimbles are too confined for
live-aboard purposes. I've no connection to the sailingtexas boat, just happened to see the listing).
