Tommaso Spadolini presents a new concept for a 48 metre yacht with large spaces for long cruises

The owner had very specific requirements: large open spaces to the stern, large windows, tender in the bow and a social flybridge. In addition to an owner’s suite, four passenger cabins, crew quarters and captain’s quarters

The concept for the 48 metre yacht by Tommaso Spadolini

The architect, Tommaso Spadolini presents his concept for a new 48 metre yacht stemming from the specific requirements of his client. The designer was commissioned to carry out a feasibility study for a more spacious yacht than the owner’s current 35 metre, allowing him to best enjoy his summer vacation with his family.

The windows – explains Tommaso Spadolini – had to be large, the owner’s suite had to be located on the forward main deck, while the four guest cabins and four crew cabins, along with the captain’s quarters, had to be on the upper deck. The tender, seabobs and an Optimist had to be in the forward section, so as to leave space aft for a gym and beach area with collapsible gunwales to expand its size. A solution that further increases contact with the water and  the surrounding environment. Lastly, a flybridge that was a perfect example of space for relaxing in company.”

The owner also had precise requirements for the common areas of the interior, with a large galley aft of the owner’s suite, followed by an 11 metre saloon, while another 7 metre saloon is to be located on the upper deck.

Obviously, in this phase – notes Spadolini – we have not looked at furniture, but indications from the client suggest he is after solutions including modular sofas and armchairs. One of the details we can share is that the balcony of the owner’s suite will come out laterally from the side, guaranteeing the utmost privacy.


The displacement hull is 48.5 metres in overall length, becoming 46 when floating for a maximum beam of 8.8 metres and a draught of 2.5 metres. The hull will be built in steel and aluminium will be used for the superstructure, with a gross tonnage of approximately 490 tonnes.

It will have a pair of Caterpillar CAT C32 engines from the professional working series, allowing the yacht to reach a maximum speed of 16.5 knots, with a cruising speed of 13.5 knots. Upon the owner’s request, autonomy should be around 4,500 miles, at an economic speed of 10.5 knots, so that all types of navigation, including ocean crossing are possible.

Also based on the client’s requirements – says the designer – we created a classic yet modern profile for this 48 metre yacht. We were expressly asked to use a semi-vertical bow and other specific choices: for example the fly has ample free space and for this reason, we have not included the usual hot tub. In short, it will become a very large solarium with modular furniture that can be arranged depending on the occasion. The relationship with the water is mostly given to the large beach area aft, and its comfortable and inviting access to the sea.

 One more thing – concludes Spadolini – regards the many solar panels, which can guarantee good energy autonomy, not only for enjoying evenings under the moonlight without hearing the generators in the background, but also to care for the environment, which is something the new generations care about deeply.
