Final update on this thread.  After 2 and a bit weeks the varnish cured.  There were a couple of small areas still very marginally tacky but I gave it a sand, wiped down with mineral turps (spirits) and gave it two more coats this weekend.  Both cured properly each night.  So I have finished the varnishing (2 coats epoxy, 3 coats UV rated marine varnish).  There really isn't much varnish on this boat and it really only takes a half hour to give it a sand and a coat so hopefully I can keep it in good nick each year.

So it could have been a few reasons why there were problems. Paul suggested epoxy should be left 3 weeks before varnishing to properly cure.  There was extreme humidity in the hours after applying.  The manufacturer thought there might have been a contamination issue (amine blush?).

Anway all's well that ends well.

Thanks for the inputs and ideas.
