On my C250 it is a big concern. The gutter around the cabin hatch is designed to drain forward into the anchor locker, from which it drains out the bottom. If the waterline is elevated in the front the slightest bit, that water drains back and collects in the back of the gutter until it gets high enough to penetrate the gasket and drain into the cabin. YMMV, but beware of these hidden design issues that can flood your boat unexpectedly.

I picked up a laser level on sale for $5 at Radio Shack and mounted it on a camera tripod. After making sure the level was perfectly vertical (using the bubble on top of the level) I could pivot it to point the laser dot at the bow and then at the stern. This gives a very precise measure of level, without having to climb up and down on the boat repeatedly. The buckets of water are useful for a final test.

In the yards around me, the vast majority of boats have their masts up while on the hard.

Actually I believe the cradle being level is very much important to the OP's original concerns. If the cradle isn't level then you run the risk of putting more stress and weight on pads and stands that would otherwise be necessary.

Same here. Any idea how often boats get blown over, or how strong the wind has to be? I store store mine with the mast up (as do most others around me). I think maybe I will take a closer look at the boats that would fall on mine to see if they are set up well.

I'm not sure that the cradle is level. I think it is close. Is the problem with an uneven boat just for water drainage? The boat itself, is leaning a bit back and to port. It was raining when she was hauled and the water pooled in the cockpit. I've mopped the water out and left a few flat pieces of foam on the cockpit floor with a brick on top - my thinking was that if water accumulated and froze, the foam would compress before the ice damaged the fiberglass. Along the toerail I tied short lengths of rope with one end laying on the deck and the other hanging a couple inches over the side in an attempt to 'siphon' any standing water. Also, She'll be tucked under a big farmer's tarp (hay bail tarp).

As for the masts being left up; I think 99% of the boats still have the masts up. Now I'm nervous about my boat becoming part of a very expensive game of dominoes!

It's close, I doubt more than 1/2 inch of water could accumulate on the cockpit floor before draining out of the scuppers. I think the cockpit floor is about 4 feet long. (Math is not a strength of mine, but) I believe that's less than 1 degree from level...

A small diference can't be that bad can it? (I hope)

Yes, but if that 1/2" of water freezes, and then you have a little more freezing, soon you're talking a fair amount of weight.

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.

You should have the yard adjust the stands to get the water to drain...assuming that it drains when the boat is afloat...

Over recent years, the cost of yard insurance has gone up a lot so most yards have priced mast removal high so owners wont pay and instead leave the mast in, or the yard just refused to pull masts.

I would say most winters there is a local story about a row of sailboats falling over in a strong breeze...

Certified...in several regards...
