Just for those interested in such things, I kept a record of the components weights as I put this canoe together .... it isn't exact, but it is pretty close. The goal for this build was to lose weight, increase seat strength and not lose any structural strength, so I needed to know where I was spending my weight credits.
As Alan pointed out in another thread, it is the things you add on after the hull is complete that will make the biggest difference in the final weight, I personally believe that gunnels are almost always overbuilt and add the most unnecessary weight to a build, followed by the decks and thwarts, I also cut down on the handle size and trimmed all the hardware to length.
Component Weight Summary
Component Lbs
Cedar Hull weight 18.59
Inner Glass 5.50
Outter Glass 6.05
Gunnel/Decks 2.86
Handles/Thwarts 0.75
Foot Braces 1.55
Seat Cleats 0.96
Seat 1.32
Varnish (7 coats) 1.80
Total 39.38 ( Goal was 40 pounds)
Just to give an example, using standard 3/4" x 3/4" x 16' ash gunnels will weigh in the neighbourhood of 10-11 #s ... add a couple of 3/4" decks and that would easily float into the 13# region, this build spent 2.86 #s on the decks and gunnels, a difference of 10 pounds and I used cherry gunnels .... I didn't resort to softwoods.
I used 6 oz glass with 3 epoxy coats outside and 2 inside ... using lighter glass would give some weight savings, but it is clear from the list that this area a) isn't a major weight area b) it does/may compromise hull strength.
Just a few thoughts and extended build info ... I learned quite a bit on this build about where the weight piles on.
