it's a classic
McClaren's boats were the rival to Stohlquist's Needle Rig boats in the early '80s. The glass versions were the predecessor to the plastic P52 Mustangs. All the big water was run successfully in a boat like yours. Maybe even yours. I.E. Barrel Springs at 19,000; Gore at 4000, NF Payette at 8000, Pine Creek at 6000, Meatgrinder, etc, etc. Large, fast and stable, they were considered to be high performance in the day.
I recommend keeping it for your next high water Granite to Canon City in a day trip.
