Jim,

The traditional outfitting can be very comfortable. Did you space the ribs 
in the cockpit area so that your "butt bones" fit between two adjacent ribs? 
If not, you may want to remove a rib or cut out the bottom of a rib to make 
a half-rib. In addition to helping with comfort, this gets your weight as 
low as possible. When the Greenlanders capsize you often see their butt and 
heel impressions on the bottom of the kayak. Many of the modern Greenlanders 
use a 1/4" thick foam pad that stretches from the backrest to the footrest 
and serves to pad the seat, backrest, footrest, provide insulation and keep 
sand from getting into the lashings. With the ribs spaced in this manner and 
with the foam pad, the fit can be very comfortable.

The kayak and paddle are a tuned system, and a number of kayakers who use a 
Greenland-style SOF with a Greenland-style paddle find that they place very 
little pressure on the backrest. As for myself, I lean forward slightly and 
help drive the paddle using a slight abdominal "crunch" where you start with 
your torso erect and then lean forward slightly. This technique was shown to 
me in West Greenland and appears to be quite widespread there. (I was warned 
not to "bounce" the kayak up and down). It reminds me somewhat of standing 
on the pedals during biking. With the low foredeck common to Greenland 
kayaks you can lift the opposite knee in concert with the "crunch" to use 
very large muscle groups. This requires proper timing and feels somewhat 
like performing a sit-up with someone holding your legs. This technique puts 
very little pressure on the backrest.

Hopefully this helps, but we are all built differently, and one person's 
comfort is another's misery.
