Add another thwart attachment point with the NRS Pennel Orca Fixed Batten System. Sold individually, but you'll need two per thwart. Add this Batten System to any NRS Otter or Expedition raft. Can also be added to any other synthetic-rubber coated boat. Use the combination of Clifton Hypalon Adhesive and Clifton Hypalon Accelerator to glue these on. One-loop piece glues to the thwart and the two-loop piece glues to the inside of the boat's side tube. Includes the plastic batten.
