A night at anchor, several showers after a swim, and still enough water for the galley: the capacity of the fresh-water tank quickly becomes an issue. The Qube 30 is designed for small to medium-sized boats with three to four people on board.
What 30 litres per hour means on board
The Qube 30 was unveiled in early October 2026 at the Genoa Boat Show. According to the manufacturer, it has a nominal fresh water output of 30 litres per hour and requires 110 watts. The BOOTE overview of watermakers explains just how far you can go with that level of system performance.
Compact dimensions
Schenker describes the Qube 30 as a compact unit. Measuring around 74 × 26 × 21 centimetres, the watermaker is indeed small. However, the separate water pump should also be taken into account. The Qube range According to the manufacturer, it utilises energy recovery and operates at 12 or 24 volts. With Zen 30 and Smart 30 Schenker already has two models in the same nominal flow rate class in its range. The Qube 30 adds another design to this selection. A confirmed German list price is not yet available.
