Just a guess, but is it possible to splice some fishing line.....say 15 lb rating and 10 feet long to the spectra lines, so you can pull the lines back into the kayak for easy repair???
Then, using the fishing line to pull the spectra line back out to the rudder assembly.......again, just a thought since I can't see exactly what your Sport looks like on the interior....
I think I will tie a line around the bungee and the cord and try to bring it around a scupper post or something else inside to use as a stationary pulley and stretch the bungee tight. Then I can reach in with the crimper and get it in the right spot. I tried a cable tie but it was too hard to do it blindly.
I don't want to mess with disconnecting the spectra at the rudder drum for more slack evefn if spliced at the end to pull back again; I'm afraid of messing it all up!
Thanks for the suggestions everyone
