CPI is Curtis, seems to be their 99th hull, probably overall, and was laminated in December, [L], of 1983. The solo tripper was replaced in the Curtis line with Nomad,a shouldered / tumblehomed hull in ~1989.
It is the First of several David Yost designed trippers, including, in near order, Sawyer Autum Mist & StarLite, Curtis Vagabond & Nomad, Loon works Mistral, Swift Heron & Loon, Bell Merlin II and Placid Boats RapidFire.
Of interest, Solo tripper was the only DY tripper to be flared. All the rest are tumblehomed to improve ergometrics and paddle physics.
