Dumas has recommend fiberglassing the deck and hatch at this time.  I have already added two coats to finishing resin (sanding between coats) to seal the deck.  Fiberglass is not needed to provide support/strength the the deck.

  What follows are instructions written by me, NOT DUMAS.  If you use these instructions, Dumas will not be able to provide any support.  I have received many emails over the years asking questions about building the superstructure.  Questions where the modeler is simply "lost in the construction process".  After I read through the instructions that Dumas included in the kit, I can see how they are a bit vague.   So I will show you how I built mine.  Remember, this is only how I build mine, this not a "set" way.  Feel free to review my steps and build yours as you see fit.

    

Cut out and mark the parts for the superstructure.

  Dumas tells you that the superstructure is built up on the boat rather than on the building board, for the most part, this is true. You need to refer to figs. 3, 4, 5, 6, on the plan for construction drawings.  Study these drawings.

  Cement the 1/8" sq. spruce to the inside surface of the right and left, upper and lower deck sides. Follow the drawings on the plans as a guide.   Also cement a piece of 1/8" sq. spruce between the middle notches in C-1. This strip will support the front edge of the lower cabin top.

  Lay the port (left) lower cabin side on the bench then place the upper cabin side in position and mark the lower cabin side where C-2 should be located. 

  At this point I assembled the following superstructure parts.  I used masking tape to tape the lower cabin sides to C-1,  C-2, and C-4.  I placed the superstructure in the deck opening and checked the fit.  Make a mark on the inside of the lower cabin sides at the location of Frame 9.  Check the fit of C-3.  Remove the superstructure and remove tape.
