Built by Castoldi Jet Tender in 2022, Castoldi Tender is a 10.5-metre motor tender based on the JT34 model. Designed and manufactured by the Italian builder Castoldi, this vessel stands out as one of the fastest superyacht tenders available on the market, capable of reaching a maximum speed of 50 knots while maintaining a strong emphasis on maneuverability and onboard safety. Its versatile convertible design makes it equally suitable for passenger transfers, sightseeing cruises, dive site transportation and water sports activities.
One of the defining features of this tender is its retractable watertight soft-top roof, which converts the vessel from an open-air layout to a fully enclosed cabin with a generous headroom of 2.27 metres. This dual configuration provides both the freedom of open navigation and a comfortable sanctuary in less favourable weather conditions. The interior offers a full-beam living space with a circular seating area, sunpads both forward and aft, and a practical layout well suited to passenger comfort. Access on and off the vessel is made straightforward by a hydraulically actuated landing ramp operable from the sides, stern and bow. Propulsion is provided by two 440 hp diesel engines paired with two Castoldi water jet drives, and docking is simplified through a joystick piloting system based on the Castoldi electronic control system. The reduced profile of the tender also facilitates easy storage aboard a mothership.
This tender is well suited to superyacht owners seeking a high-performance, multi-purpose vessel that can serve as both a stylish day tender and a capable utility boat. Its combination of speed, passenger comfort and versatile access options makes it a practical choice for those who require reliable tender operations across a range of conditions and activities, from leisure excursions to water sports support.
