By "the rigging" i assume you mean halyards and mast stays? (I'm a laser sailor and know not of this "rigging").
I'd suggest all the wire and rope be replaced.
It is 3 inches with the hulls flat.
Hulls are externally are excellent - one or two chips in the gel on the bows but otherwise excellent.
The only cracks on the hulls I could find were around the "tubes" that the aluminium bits that attach the hulls to each other. This looked to me like a crack in the gell coat.
This does worry me somewhat. Have the hatch covers been off at all? Has the boat been in the freeze / thaw? This will be V bad news with water in it. The epoxy work inside the hulls can be suspect at times and I'd ask the current owner he will let you dry it out fully and then sail it. If it does not leak much in a good hour sail in good wind then it's probably sound. Again, what state are the skegs in. How old is the boat? In old boats, foam was just stuck into the boats to add volume if the hull is holed, they were not structural.
blocks are "race pack" (what is this?) and were removed.
Ball race blocks (not Harken, custom laser kit)
Before he laid it up the guy was serious - going round the country to races - so it should all be good.
(also comes with Dart 15 sail he used for playing about in high winds)
remember this boat is for fun and remembering the good old days when I used to crew a Dart as a teenager. The Laser for serious racing so I'm not too worried about ultimate performance, but I would be about mast falling down!
Cheers
So subject to above make sure you change all the rigging before you sail it much.
