After the fun albeit wet (for some) trip to HPP last week, one thing to improve and aid others retrieving ones boat maybe consider putting tape tails (NO LOOP) on the ends of your boat. They can be tied or clipped (see Jack or Harrys boats)
These tails are useful on rapids such as HPP as the bank edges are vertical and flow is fast.
Talk amongst yourselves and do a tape bulk buy.
See you on the river.
