You are welcome to come and see my rigging. All pairs of stays were checked before they were installed, they were perfect. I use a digital caliper between the end of the swaged screw thread and the rigging screw on each pair to ensure the mast is perpendicular. How else would you know that the mast is upright?

That happened to me, I think in Warsash, back in the 80's...a convoy, three cars and runabouts on trailer, I arrived first and drove onto the slip beach, tide was out, and did a U turn which took me off the hard into the putty.
New car up to its axle in mud,trailer at an angle so couldn't release the coupling tide coming in a bit too fast (praying for Moses) luckily a tractor was passing.....
 
We hoist a tape measure up the mast to check it’s perpendicular to the boat. Regularly, as it’s a one design race boat. People do just use the halyard, find on a cruiser where you’re not worried about a few mm.

How does using a halyard make any difference to using a tape if one wants to check if the 2 dimensions are the same?

Plenty of ways. Halyard locked off and measured to each chainplate is the easy way. Sighting up the mast track is also very important. Do that at rest to check it's straight when at the dock, but also do it when sailing upwind with everything trimmed correctly to check that the mast is still in column when actually sailing. If it isn't then the balance of your lowers and caps is out.

The Caliper trick is not really for initial setup, that should be done by measurement to chainplates and loos gauge. The Caliper trick is for coming back to a known setting when you're tuning the rig for different wind strengths.

And simply being upright is far from the end of the story.

But as to beginners making mistakes.... I know of a very well campaigned yacht, with lots of trophies, that lost its stick on a fastnet because they tuned the rig pre start and forgot to put the split pins back.

Pal of mine had his car roll down a slip and ended up with seawater past the sills .... when he claimed on insurance - their reply was "Write Off" .. and explanation that any work to re-instate the car was most likely wasted effort as the seawater would have started corrosion.

I once bought a 4 year old car for £3000. It looked fine and was cheap so I bought it.

After about 5 years the rear wheel arches were rusting, not something you see often on that make, and by the time I had it 10 years, it failed an MOT on a rusted sill. I got it patched up and then started looking for my next car.

I strongly suspect it might have been used for boat launching and dunked in the sea, but it was cheap enough when i bought it that it was a cheap car for the 10 years I had it. I would love to have known the back story.

If you know the stays are of equal length what is the point of either, halyard or tape? Perhaps discontinuous rigging might introduce differences?

Because the difference you are looking for once the mast is rigged is well inside the margin of error you had in measuring an un-tensioned stay of say 10m or more before you rigged it. Not to mention the question of if the mould your boat popped out was exactly to the mm symmetrical, and if your mast is exactly in the middle of the boat, or if your spreaders are exactly the same length, and mounted in spreader brackets that protrude exactly the same amount from the mast each side. And then are your chainplates mounted exactly equally on a vertical plane... etc etc.

Of course you want to measure your stays before you rig to get them as even as you can as a starting point, but you cannot rely on that to ensure that your mast is straight upright in the boat.

Did it have a towbar ?
After our devastating floods a few years back…hundreds, if not thousands, of cars were towed away by the insurance companies…whatever happens to them after that no one knows

It wasn't from the Thames was it...I knew a guy who bought a bilge keel and cut the keels off to use it on the Thames..

No it was in West Wales up on bricks. Me and my brother fabricated steel hollow keels in the shape of the keels on the boat next door and filled them up with shot blast and bolted them on. It sailed like a house brick😁

Doesn’t guarantee your mast is upright. Uprightness depends on whether your hull and chain plates are perfectly symmetrical. Etc.

In practice no boat is perfectly symmetrical.

edit: I see Flaming has got there first with a better and more detailed explanation.

Halyard or tape…..

Stretch in the halyard? Innaccuracy on where exactly you are measuring to, etc. A measure is best, that’s all. We’d ideally like to be within 2mm, certainly within 5

I'm actually surprised you think your chainplates are that symmetrical on an XOD.
