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)


Not sure where you are getting the above rules and rule numbers from, but the current 2009-2012 Equipment Rules of Sailing have the following:-

G.6 SAIL REINFORCEMENT
G.6.1 Primary Reinforcement
An unrestricted number of additional layers of ply of permitted material:
at a corner
at a adjustment point
at a reefing point adjacent to the luff
at a reefing point adjacent to the leech
at a sail recovery point
where permitted by the class rules

And Tabling:-

G.6.3 Tabling
Additional ply or folded ply overlap(s) at a sail edge.

Note: the Tabling rule falls clearly under G.6 Sail Reinforcement, and the Class rule approved cloth list refers to "Spinnaker Reinforcements,
Any sail cloth on the spinnaker list"

From the Class rules:-
G.5
G.5.1
(a) The ply fibres shall consist only of nylon or polyester materials as detailed in Spinnaker Sailcloth Appendix.
(b) Sail reinforcement shall comply with Spinnaker Sailcloth Appendix.

To be correct in allowing additional cloths to be used in Tabling then those cloths should be defined in the cloth list.
