Personally, I wouldn't want that on the upper Duc due to size and weight. People with good skills and knowledge of the river CAN make it down in driftboats but you'd better not f' up. Good to go on the Hoh but don't know why you'd pick that boat over your db? My guess is that the toon will take more effort to row and and you won't be able to slow yourself down and hold in water anywhere like a db. Sounds like a good craft for extended camping floats though on places like the Grande Ronde or Deschutes.
