thanks for the replies. I gather that the boat is NOT good for short handled sailing then, but does have ample space.
I wouldn't say that, no. The one I've been on is owned by a couple in their 70s, one a cancer survivor, but I think they are very careful with the weather and motor more than most.
The Cal 2-46 is a fairly heavy displacement motor sailer. Its progress under sail could be described as "stately"...it's not going to win races, unless they are long ones, and there's an element of endurance to them. By that I mean I would think they are possessed of an easy motion at sea, and can carry a LOT of tankage and stores.
In the ketch version, the sail plan of a 46-foot boat is more like that of a 40 footer, thanks to the division of the sail area between a big jib, a small staysail, a (usually) stumpy main with a long boom (meaning the first reef depowers the sail a lot), and a mizzen that, when used with the staysail alone (no main, no jib) is a great way to do hull speed at 40 knots on a broad reach.
So a fit couple can handle that, or even a cutter, if they have big winches, lots of reef options and nice, heavy gear of the Garhauer "better twice as strong as needed" type.
I know some fairly older couples are out there with new 50-footer with electric winches and push-button reefing, but I think that is going to cause grief at some point. That's why I say that a Cal 2-46 is about as big as I'd want to handle, because I can picture handling it...just...with emergency tiller steering, a trysail, a dead engine, a first mate with a broken arm lashed in her bunk and water over the floorboards. In other words, a worst-case scenario 98% of sailors will not likely ever see. My own plans take into account some fairly grim possibilities, and I've sized my boat backwards from that in aid of prudent seamanship. This is why we have a steel motorsailer cutter of some 41 feet in length...because that's the biggest boat my wife figures she could sail solo if I was the crew lashed into the berth with a busted arm!
Now, if you intend to basically cruise coastal, the Cal 2-46 is like a '70s Cadillac...smooth riding. But it's fine going around the world, too, if you as crew have the skills to keep her moving.
If it's clean, has been kept updated and has no glaring structural or engine flaws, I would certainly consider it if you want a comfortable boat capable of being a liveaboard.
