Martin, Im offended that yo seem to think my claims are without base. Maccas are without base.

From Isaf Measurement rules.

1.6.1 Primary reinforcement

An unrestricted number of additional Ply of Permitted Material.
At a corner
At a cunningham Point
at a reefing point adjacent to the luff or leech
at a spinniker recoverery point
Where permitted by class rules

Quite clear wouldn't you say. This is for the primary reinforcing.

Now for the block gumbys or tabling

Rule 1.5.8 Tabling

Additional ply or folded ply overlap(s) at the edge of a sail ( Tabling may be in addition to Permitted reinforcement)

So these 2 rules make it perfectly clear that primary reinforcing should be made from stuff permitted in the body of the sails (as permitted in class rules), and tabling is in addition to the primary reinforcement.

Any good sailmaker is aware of these rules. Its part of his job. SO ill say it again that they knew what they were doing was wrong and got away with it. Even got away with a world championship. And now seem to be pointing the finger at other sailmakers, whom i guarantee are doing the right thing, and saying "look he did it too" like some sort of spoilt brat. Disgraceful.
