Commissioning a 1988 Laser that has not been used in many years

No. But I've seen a boom being rejected at measuring during the World Championship Radial U19 in Kiel. The boom (and other mast parts) are compared with a tech drawing spread out on a table. One boom was obviously (and visible) not straight anymore. The girl had to source another boom (we had a spare one in the trailer).

How would anyone (ILCA enforcer) know if there is a reinforcing sleeve or is a LP part or of a certain length?
The length and location are easy to measure through the hole in the front plug with a long stiff wire or some such. Of course you can't see whether it's an original part or not, but that's beside the point, which is rule compliance in general. Is it ok to cheat if you don't get caught?

What if my top mast connection fitting has 3 rivets? Even more susceptible to breaking or is it more reinforced?
It's even more likely to break! If you go sailing with that, be sure to rotate it so that the middle rivet points aft. But yes, that spar should really be end-for-ended.

Lots of talk about old booms breaking. Mine (1981) took a hellish beating and bending for many years and never broke, while mast sections (upper and lower) broke several times. Any YouTube videos of a boom breaking? (Now, I do have the new one with a sleeve....)
Boom were fully sleeved by the year 2000 or so, well before GoPro cameras.
Sleeved booms are pretty bulletproof so no videos of any breaking.

But if the manufacturer no longer provides the class legal sleeve, I would not feel bad about using a similar generic alu tube.
BTW, I have a class legal sleeve on order with ASP for a backup boom; we'll see if they deliver.
If I only had one boom and needed a sleeve, I would not wait for the class legal sleeve.
Order the class legal sleeve but in the meantime install a generic tube so your boom won't break.

I went out and took some pictures of the boat. It needs to be cleaned up a bit.

On the lower section of the mast there is a metal ring and I forget what it is for.

I had modified the boat to be able to adjust the sails from either side, so there are 3 clam cleats on either side, but I am planning on going back to the standard official set up.

I bought all new lines from APS and a newer Laser Race Vang from LaserPerformance.

My sail looks to be in good shape, but I won’t really know until it is used. It is the older style, not a MKII.

The top section of the mast has 2 rivets. They are 180 degrees from each other and one is at the top of the black plastic ring while the other is at the bottom of the ring. Does it still need to be flipped? I will be sailing on a lake with generally very light, 6 knot average, winds.

My rudder and daggerboard are in decent shape. The front edges are a little worn and the paint came off, but no major dings.

How can I tell if the boom has the sleeve inside without taking it apart? Does it really matter in light winds? For the cost of buying and installing the sleeve I could pretty much replace it if it breaks. It seems like a lot of work to put the sleeve in.

Any other thoughts about what you can see from the pictures?

Thanks

Perhaps to attach one end of the downhaul? The clam-cleat behind the compass puzzles me, though.
More modern solutions for the downhaul look like this:

Yes, the clam cleat between the compass and cockpit is for the down haul.

Where does the other end of the down haul go to in your picture?

Probably has to do with the double-ended controls, which don't look very well-working at all (in addition to being spectacularly illegal). Get rid of it, and the fairlead below the vang tang as well. That lower mast has quite a few extra holes to snap at.

Good.

Their being at different cross-sections does reduce the risk somewhat, but you might as well end-for-end the spar anyway. It's not a huge job.

As I said, stick something thin, long and rigid through the hole in the forward boom plug. If the sleeve is there, you will easily feel its forward edge.

Fitting a new sleeve does take some work (just getting the old plug out can pe a real pain), and although it makes the rig nicer to tune in all conditions, it's a safety feature only in heavier winds.

There is definitely something inside the boom. It starts about 6" in from the end. I assume that is the tube that you all have been talking about. Yeah!!
