I owned a 12 ft. Hyside and used an NRS fishing frame ( put together with parts, not the stock version) and the stern frame. My stern frame was for the anchor system and I didn't have a seat on it. My Hyside was 6 ft. wide and I used 8.5 ft. oars. I think the frame was 65 long and 54 wide. The chart on the NRS website recommended 8 ft. oars, but I thought they were too short.
