Pulled out the horses so I could work on Duh!k at a reasonable level. Pulled all the old foam out of the seat area and cleaned things up. Found one of the ribs had taken a convex curve on the width at the bend and that was what was riding on those nerves, bones and blood vessels. It was definitely the problem all along as it was that cheek that was aching. A strip of 80 grit and some elbow grease and I smoothed that lip out and rounded all the corners just a bit more. Not too worried about structural issues as there is another rib 2″ forward of that one. Touch up the area I just worked on with some tung oil and spent some time looking at things, thinking.
I gathered up some materials, 550 cord, another sheet of 1/4″ foam, contact cement and I was ready. I laced that cord between the ribs and snugged the lacing tight then locked it with a double hitch on the end to hold it all in place, then moved the boat to the floor for a test fit. Much better even without the foam pad. Back to the horses, cement and foam layed over the lacing and a bag of sand to hold it in place while things cure. Without taking her out and doing a long run like I did this past weekend, I can’t know if this ‘fixed’ the issue or not, but things definitely felt better. I may find my balance point is higher too and that will effect handling. Maybe she’ll turn now. Maybe she’ll roll like a spindle on a lathe. Can’t know till she’s afloat with my knock-brained self in it.
I will use this for the next Yak before it gets skinned as its much easier to access the area then.
I also flipped her over to really get a look at those wear marks and was even more impressed by this skin. There are three places where the outer urethane was rubbed off right to the nylon! She never leaked! Not one drop! The water I had in her when I got out was from my shoes when getting in her. Not enough to reach the end of the bilge pump and barely enough to get with the sponge. What was in there flowed out when I hefted her up to portage up the bank for pick-up. (Note: the bottom finish was done in three layers. The first to saturate the cloth, the second to fill any odd spots and the final to smooth it all over.)
I’m going to go ahead and order the touch up kit anyways, but it is not essential, more cosmetic; and peace of mind as where its worn won’t take as much to wear through. $15+s/h is cheap peace of mind in my opinion.
Now I’m anxious for another day on the river. We had a little rain today, and are expecting more this week, so it could be the water level will be up some. That makes for a more enjoyable run for certain. Even if I don’t get things touched up, I’ll get out and see how my modifications worked out.
