Eastern Arctic Kayak Construction adding the deck beams

Construction progresses.  After I set up the deck, I started adding deck beams.  They are temporarily nailed in place 3/4 inches below the top of the gunwales. 

Before starting to add deck beams, it is a good idea to stabilize the deck by lashing the ends together and also doweling the two sides together so they dont shift with respect with each other which would cause asymmetry in the deck.

And here, at the end of the day, all the flat deck beams are trial nailed in place.  You could of course dowel all the deck beams in place as you go but trial nailing them lets you do some last minute adjustments in deck shape before committing to more permanent joinery.

The last two deck beams to be added are the two curved ones just fore of the cockpit.  Shaping them is more time consuming than shaping the flat ones.  Unlike the flat deck beams which are mounted 3/4 inches below the top of the gunwales, the curved beams are mounted flush with the tops of the gunwales.  A batten is temporary clamped in place to show the curve that the deck stringer will take.  The beam just in front of the cockpit will elevate the front of the coaming 4 inches above the deck.

And here is a view down the length of the boat with all the deck beams in place.  The number of beams, coincidentally is less than in a traditional boat to keep down the overall weight of the finished boat.

And just before I started adding in the two curved deck beams, I had a crisis of faith about where the widest part of the boat should be.  Seemed like it wasnt far back enough.  But then I checked back with the drawing in Arimas book on EA kayaks and it appears that my placement was OK.  Seems that the original for this adaptation was a demo boat done for a Canadian museum and was shorter than the type usually is because available lumber was only 16 feet long.  So a shorter version with a slightly more forward beam was built.  In any case, the first boat of a type is never just right and gets modified when the second one is built.
