You are in a manner of speaking working with a very flexible sheet of plywood. The inevitable result is the need for more seams to wrap that material around a series of compound curves which comprise your boat. The raw nylon does require seams as well but fewer. Just the same, they represent a weak spot in your skin and leaks can be very difficult to eliminate at times. I usualy tell people, if you don't want to get wet, don't mess around in boats.
Time goes into the woodworking.
The basic frame went together fairly smoothly bu a lot of time went int the wrap around bench and the leveled floorboards. There are also alot of little tiny knees built into that boat. I'll try to post some photos of them on my website soon. I manage to have only a short seam running up the stem and one up the transom. I wish I had mind you because I did sell it.
