I have a canoe but have yet to use it . But , I also built a steel frame across the bed of my old truck for carrying my recurve. The steel frame stays in the bed and the bow is placed in an oak cradle that attaches in about one minute by use of a 1.5 inch square plate and wingnuts on a permanent stud .
Now I have the canoe set up to use the same cradle to prevent my bow from being damaged .
The cradle mounts and removes in seconds and is presently holding the bow in the house ,,on a dresser .
Oak , woods screws , glue and self adhesive felt padding in the cradle cut outs to prevent marring the riser .
