Underwater adventures: The best superyacht submarines

Italian marine manufacturers Castoldi and Nauta have developed the Jet Tender 34 Limo, marking Castoldi's first entry into the limousine tender segment. The 10.4-meter vessel will serve as ship-to-shore transportation for a new boutique cruise ship fleet under construction in Italy, with four limousine tenders and two support vessels ordered per vessel.Giacomo Castoldi, CEO of Castoldi, stated: "This project represents a new chapter for Castoldi that expands our offerings to new markets, while maintaining the commitment to innovation, quality, and luxury we are known for." The collaboration utilizes Castoldi's waterjet propulsion technology and semi-serial production capabilities combined with Nauta's design approach.Nauta Director Guido Valtorta noted: "Typically, limousine tenders are custom-made for large yachts, but this project allowed us to merge bespoke luxury with the efficiency of semi-serial production." The design incorporates multiple boarding points, configurable seating arrangements, and ceiling lighting systems aimed at creating spacious interior environments.Technical features include Castoldi's ACES electronic control system and waterjet propulsion designed for commercial vessel applications. The tender achieves cabin cooling within 15 minutes and incorporates noise-reduction systems within rub rails. The platform allows for Open Limo and Support Vessel configurations through modular design principles.The first unit is scheduled for delivery in late 2025, with project presentation planned for the Monaco Yacht Show. The tender measures 10.4 meters in length with limousine-style enclosed cabin accommodation. Production follows semi-serial methods rather than custom one-off construction, representing a new operational approach for Castoldi in this vessel category.The partnership combines Castoldi's marine engineering capabilities with Nauta's yacht design experience, targeting the growing market for luxury tender operations in cruise ship and superyacht sectors. The design emphasizes functional elements including pantry facilities and toilet accommodations within the compact hull form.Credits: Nauta
