Our own Glenn Ashmore developed a perfectly elegant scarph jig which used a
router and a long straight bit. I've shamelessly copied it. Glenn- I
recollect that there were photos.

I am building an Arch davis design Penobscot 14 and I am at the point
to scarf plywood for the panels. I am hoping there is a jig design to
cut the scarfs on 1/4" plywood. I have seen jig for circular saws,
but I hoping there is a system to use with a laminate trimmer or a
router for cleaner cuts. Any help would be greatly appreciated.

Yeah. The only picture of the router jig is about half way down on the
Cabin Top page http://www.rutuonline.com/html/cabin_top.html . With a 2"
straight bit on a 9:1 slope it will scarf up to quarter inch plywood. Any
thicker than that and I resort to the power plane and belt sander method.
With the thin ply lines of marine okoume and meranti as a guide it is fairly
easy to cut an even scarf by eye on any thickness with 5 or more plys.

The trick is to keep the ply lines straight and not to cut into the edge of
the face veneer or the joint will show to much. and have gaps.
