By the way, the two stands that I could see forward of midships WERE chained together across the boat. But the starboard one had tipped over, possibly a sign that it was extended too high, and thus the stand may have been torqued by the windage, with the chain below the center of torque.
When I bought my stands, I made sure to buy the largest ones that would fit beneath the boat (and drove up to the Catalina dealer in Riverside to inspect several C250s on the hard to verify my measurements). None of my stands are extended more than 6" out of their bases.
My compliments on your thoroughness. Driving to see a sister boat on the hard, to check measurements. Nicely done.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Came across this last week. I never feel good about mast up winter storage for a myriad of reasons but the number one reason is the added windage to the vessel. On land you don't have the keel opposing the vessel from the forces of wind only the boat stands that are meant for balancing the boat. A sailboat is far more stable in the water than on land and leaving the spar up can add unnecessary windage.
This boat was roughly 28 feet & this is what I saw:
1- Three stands per side + 1 bow
2- All stands had been chained
3- Boat was on solid cement parking lot
4- Boat was on proper wood keel blocking
5- Boat had mast up and apparently a huge gust blew her over.
I don't know what else could have been done differently in this case as everything was done by the book by a very knowledgeable yard. The only difference between this boat and all the other mast up boats is that this one faced beam to the prevailing winter winds and the others faced bow or stern to..
The boat yard we store at has a full disclaimer document that says if you choose to store mast up you and your insurance company are liable for any damages caused if your boat tips over.
I was back down at my boat today and I had a better camera and a little better light. So I wandered back to that other boat yard to get a closer look at the boat that fell over. I have some much better pictures, and a better idea of what happened.
The boat was definitely up on concrete cinderblocks - bad idea. You can see evidence that the mast got pushed to starboard, and the blocks fell to port due to torque on the mast. It makes me really glad I dropped the mast on my boat. I did it because I wanted to do some upgrades on the masthead over the winter, but I think I'll drop it every year now that I've built a gin pole.
And contrary to what I said before, you can see unpainted spots where the pads had been - and the new grey paint in the edges of the pads. So it's possible this guy had not moved the stands.
FYI, the registration sticker on the boat expired March 2010, so this would appear to be a restoration job.
I had previously suggested that the stands were extended up too far. You can see by the position of the cam screw that this is not the case here.
Since I had more time to look around, I checked out some of the neighboring boats and saw lots of examples of poor practices - concrete blocks under the keels, stands too small for the height, and insufficient number of stands. I am SO GLAD that I decided to go elsewhere to store my boat:
