Auxiliary Power/Water (orig. equip.)
According to the CAL 29 brochure, the CAL 2-29 is a "special cruising version of the CAL 29...and includes, as standard equipment, a diesel engine, pressurized shower, pedestal steering, vanity with medicine chest, electric bilge pump, extra water tank and shore power system." So both the 29 and the 2-29 must have been built at the same time, though the first 2-29 must have been introduced somewhat later than the standard 29. Many thanks to David Burnham, CAL 2-29 owner, who solved this mystery and kindly offered his original brochures to prove the case.
