G'Day Rafael, I had a similar problem and followed a similar strategy to Craig on two boats now. Something that made a huge difference was to cut two 4cm to 5 cm diameter holes in the padding to match the two "bum bones" (ischial tuberosities I think they are called but doctors on the list might confirm this) and a smaller hole to match the base of the spine My "friends" of course made much of the possible ways I might have located these holes, making reference to sitting in buckets of rouge and then sitting on the seat to see where the pressure points were. None of this is true, honest! I found the pressure points by examining an old seat pad and looking for the indentaions that were left after a long and uncomfortable week or so of paddling. This reference might help. http://ergo.human.cornell.edu/DEA325notes/sitting.html All the best, PeterO *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
