tabbing, in most of the kaying context, means simply to use non-continuous spots of epoxy/epoxy filler along a seam or bulkhead to get the hull panel or bulk-head locked into position so that you may then remove temporary attachments (like copper wires or glue-gun glue) before going back again and actually glueing the entire length of the seam over its entire length.
the building instructions for the wr180 (which was the precursor to the wr18) basically suggests this technique when they refer to putting peanut butter consistency epoxy into the outside seams between the copper wires. and then once set, removing the copper wires and filling in the gaps.
this is a little unusual to those who have not built a multichine boat becuase, typically, "tabbing" occurs on the inside of the boat where there is a fillet being built up between the panels. but becuase the wr18 really has no interior fillets other than at the bow and stern ends at the keel seam, and around the bulkhead, the tabbing for the most part is occuring on the outside.
once your hull is secured with this tabbing, you can remove your copper wires easily...they should just pull out.
on the wr18, the only area tha you need to pay a bit more attention to is is in the bow and stern keel fillets and the bulkhead fillet. if you decide not to "tab" these fillets prior to completing them, you will likely need some heat in order to be able to cleanly remove the copper.
