Castoldi JT 21

The Castoldi Jet Tender 21 is a high-performance Italian-built RIB tender, designed specifically for use as a versatile yacht and superyacht tender.

Measuring approximately 6.26 metres in length, the JT21 combines a lightweight Kevlar and vinylester hull with Castoldi’s renowned waterjet propulsion system, providing excellent manoeuvrability, shallow-water capability and responsive handling.

This model is powered by a 260 hp Yanmar/BMW 6BY 260 six-cylinder diesel engine coupled to a Castoldi Turbodrive waterjet system. With a capacity for up to 12 passengers and speeds of approximately 40 knots depending on loading and conditions, the JT21 offers an excellent combination of performance, practicality and passenger capacity.

The waterjet propulsion system eliminates the need for an exposed propeller and provides precise low-speed manoeuvring, making the tender particularly well suited to guest transfers, beach landings and watersports operations.

The Castoldi Jet Tender 21 was designed around its waterjet propulsion system, providing exceptional manoeuvrability and impressive performance for a tender of its size.

Its shallow draft makes it particularly suitable for beach approaches and shallow-water operations, while the absence of an exposed propeller provides an additional advantage when operating around swimmers and during watersports activities.

With seating for up to 12 passengers, strong acceleration and a compact overall footprint, the JT21 remains a highly capable superyacht tender for guest transfers, watersports and general yacht operations.
