Castoldi

Castoldi is an engineering pioneer in advanced waterjet propulsion systems, developing heavy-duty marine drives for commercial and recreational applications. Established in 1962, the Italian manufacturer transformed marine propulsion by introducing integrated, high-efficiency waterjet drives designed to overcome traditional limitations in maneuvering, mechanical drag, and system complexity.

The brand’s proprietary waterjet technology stands out due to its self-contained architecture. Each unit incorporates a heavy-duty integrated gearbox with hydraulic multi-disc clutch, an advanced impeller design, and protective grid clearing mechanisms like the Clear-Duct system.

This compact construction eliminates the need for external marine transmissions, streamlining installation across custom tender builds, high-speed patrol craft, and passenger ferries.

Manufacturing operations are centered at an 18,000 square meter facility featuring specialized production sheds, administrative offices, a private testing basin for real-time vessel trials, and an on-site helipad. Operating under ISO 9001 certification, the company builds propulsion units compliant with major international classification societies, including ABS, Bureau Veritas, DNV, RINA, and RMRS.

Through continuous hydrodynamic research, CAN-bus electronic control systems (ACES), and hybrid-ready propulsion integration, Castoldi delivers durable, low-maintenance propulsion solutions. The company remains a global reference point for high-maneuverability, shallow-draft propulsion across demanding marine sectors.
