I did one cut down the centre, same as the bow only did not remove a "V" of extra material.  That meant I had two layers of glass on the transom, biggest challenge was to not get the underlayer ballooning up when trying to smooth out the top layer.  In the end it worked very well. 

Also, if you have not already, check out Laszlo's very informative site on building a WD12.  I especially like the tape on the hull when glassing the deck as well as the plastic to cover the deck while epoxying the coaming so that you can remove it and finish sand before final mounting.  http://morocz.com/BoatBuilding/DuckBuild.htm

Enjoy the jouney and I look forward to welcoming you to the flock :)

I have checked out Laszlo's sight and it has helped alot.

Thanks for the "glassing the transom thoughts".  It makes sense to make one slit and overlap.

Glassed the exterior of the hull today.  It was very intuitive when it came to the bow and stern.  Overlap of the bow was as advertised in the instructions and the glass layed down just fine.  The stern worked good with one cut and overlap the transom with both pieces of the side of the glass, I let the glass overlap about 2 inches on each side and the glass stayed down with no ballooning as it cured.

Thanks for your help and advise.
