I have an aire travaler cata-canoe with a frame I made using NRS fittings and aluminum tubing. The frame currently has NRS high oar stands and the seat is connected on a basic ubolt low base. This next summer I would like to start doing more whitewater with this set up. My whitewater experiance is limited to the gulkana and kisarolic (both of wich I though was relitively easy). The one Item that worries me about this set up is will I be able to get the paddles far enough out of the water on my forward stroke to prevent them from draging in the bigger waves? I think my oars are 11ft. I am contamplating building both my rowing seat and oar stands higher by welding another tube 6" higher than the base frame. I will be switching seats to a padded rowing seat also. Is this a good idea? I was just wondering how everyone elses frames are set up and if you have any experiance in whitewater with them.
