Ironandwood, I also just viewed your PM and responded. Just like lowangle I do not have access to the Tripper, but will gladly take measurements when I return from vacation. With my OT Tripper experiences and recognition of the factory seat locations, modifying the seat locations would probably be a good idea. I feel as though the seats are rather high (should be lowered) and that the bow and stern seats should be moved approx. 4-6" towards the center thwart. The proposed new seat locations are just a guess at the moment without actual measurements, however the factory installed molded seats from the late 1980's would need to be replaced if that were to happen. I would actually prefer webbed seats or natural cane seats over the molded seats anyway. Just my opinion. Since the canoe is my fathers, I will not modify the canoe until a much later date, but I can guarantee that I will modify the seats without question when that time comes.
