Overview
About this vessel
The Sparr Norderstedt Twin I is a 1973 design by Fritz Hartz that was entirely rebuilt in 2013. The original plywood was used as a mold for the new polyester superstructure. The vessel features a teak cockpit, a laminated keel, and is registered in Germany.
The yacht is powered by a single Yanmar 2JH4-UTE diesel engine producing 100 HP, with hydraulic 2 drives built into the hull and propeller driven via shaft. The vessel achieves a cruising speed of 5 knots with a maximum speed of 7 knots, consuming approximately 3 liters per hour. The engine was serviced in September 2024 and has 1,900 operating hours.
The electrical system is built around a 12V battery bank comprising three 200 Ah lithium batteries installed in 2021, supplemented by a 70 Ah engine battery. Power generation includes a 150W Victron MPPT solar charger, a 60W Superwind MPPT wind generator, and a 120W battery alternator charger. A Victron Multiplus 12V/3000W inverter supports both 12V and 220V systems.
Fresh water is supplied by a Schenker watermaker producing 50 liters per hour. The interior accommodates two cabins with a total of four berths plus two single berths in the saloon, with a converted workshop area. Interior headroom is 1.90 meters. The galley on the starboard hull includes a three-burner gas stove, microwave, and 60-liter refrigerator. A single electric toilet with a recently serviced pump and a cockpit shower complete the facilities. Hot water is provided by the engine via a 30-liter tank installed in 2013.
