dbash356,
Since I have the R31S, I can't tell you anything about the Command Bridge capacity on the R31CB.
However, for sleeping quarters, I believe the two models are comparable. Two adults sleep very comfortably in the V-berth since it is large and has a partial walk-around bed. My wife loves that part compared to the R27 crawl-in V-berth that we owned previously. The mid-berth (the cave) is good for two children or one adult. Then, you can sleep two small children on the cushion that goes over the salon table. I don't see how a large adult could sleep there. We put a memory foam topper on the V-berth bed and the mid-berth bed to make sleeping nice and comfortable on both.
For day-cruising, we frequently have 6 people, rarely as many as 8 people, aboard in two different arrangements. I keep two very, very compact PICO telescoping chairs aboard, which I deploy in the cockpit so that 2 people can sit in those chairs and 3 people in the aft cockpit seat with me at the helm, when cruising up to about 10 Knots. Rarely, 2 more people will join me in the cabin, for a total of 8 of us. Above 10 Knots the noise becomes a bit loud in the cockpit for conversation. If the weather is crummy or if I need to go faster than about 10 Knots, everyone usually comes into the cabin with 3 at the table, 2 at the navigators seat and me at the helm, for a total of 6 of us. With kids aboard, sometimes they like to hang out in the V-Berth.

Annual maintenance costs depend on a lot of factors. If you refer to the typical engine maintenance such as oil, oil filter, fuel filters, impeller, and zincs, then I spend about $1,000 since I have all the work done by a Volvo certified mechanic to ensure my 5 year extended warranty is kept valid. Additionally, I spend about $75 per month for a diver to scrape the bottom for about a 5 month period in SW Florida. And, every 2-3 years, I spend another $1,500 for a bottom paint job; this might be a bit cheaper than expected since I don't pay for a haul-out. The work is done during the annual haul-out for in-door hurricane rated storage during the hurricane season.
Most of our cruising is a mixture of day-cruising around Fort Myers and Fort Myers Beach and extended cruising for a few weeks at a time up and down the Gulf Coast of Florida, across the Okeechobee Waterway to the Florida East Coast and up and down that East Coast. For what I have described, the R31S is PERFECT for us! We love our R31S, even though it had some "new-boat issues" that eventually got resolved; the factory is great at helping. Over three years later, I only have one small issue that still needs to be resolved.
And, if you are concerned at all about getting into boating for the first time at your age of the early 60s, don't be as long as you are healthy and willing to take boating lessons and to learn from every experienced boater that is willing to help you. Many of us are older than you. There are lots of those helpful people out there, with many of them on this forum. Go to some of the Ranger Tugs rendezvous around the country to get to know these people. They are amazingly helpful and the rendezvous are fun!
