The world's billionaires have a long-standing history of owning some of the most luxurious yachts ever made. This can of course be explained through their wealth but also through their taste. Following the release of this year's list of the world's billionaires by Forbes, we've decided to compile the list of the richest people who according to other media publications own a yacht.


#1 Musashi | Larry Elisson | $47 billion 


 
The Japanese name of this Feadship XL-88 comes from the renowned samurai, Miyamoto Musashi, who is not only revered as the greatest samurai of all time but also as the author of The Book of Five Rings which deals with strategy, tactics, and philosophy that is still studied today. This choice of name does not come as a surprise knowing that Larry Ellison is an aficionado of Japanese culture.

Designed by the duo De Voogt Naval Architects/Sinot Yacht Design, the 87.78 metres of Musashi accommodate a total of 18 guests and a crew of 23. One of the two master suites faces forward on the upper deck, while the second one is aft on the bridge deck. Seven further double guest cabins are on the main deck.

Split-level decks provide open and shaded sun-lounging areas, secluded side pods, sheltered outdoor dining and informal seating areas, an airy and light gymnasium and a private beach club complete with Jacuzzi and vast sun beds.

It's also the first Feadship yacht built to be fully compliant with the new Passenger Yacht Code (PYC) regulations, which allows for pleasure yachts to carry 13 to 36 passengers. Building with PYC has allowed for a custom interior that makes use of veneers, leathers and exotic materials that are compliant with the new rules.

Castoldi and Nauta Collaborate on New Jet Tender 34 Limo Model
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.
