Naval Architect Sergio Cutolo Unveils a New Concept

The Italian firm Hydro Tec, relying on its founder Sergio Cutolo’s extensive experience in explorer yacht design, presents to the market its new concept design for a 57 m Explorer. The whole project has been developed with the aim to optimize the spaces onboard to obtain the maximum comfort.


The designer made preliminary sketches, adding to the project several solutions that will allow a smarter and more complete use of the onboard spaces, making it possible for the yacht to be equipped with a range of facilities that are usually more common to larger vessels.


A touch-and-go helicopter pad can thus be found on the boat, as well as a tender slightly bigger than usual; it is exactly the solution founded for the tender storage that contributes mainly to the increased space availability onboard.


Storing tenders on either side of the main deck frees up the aft part of the boat, so this could become easily a beach club, a sauna area or a garage for additional toys. There is indeed the possibility to set up an area dedicated to the storage for a small Triton submarine.


Besides the challenge to create on a relatively small platform a real oceangoing vessel, the yacht was also wanted to be suitable for exploration in cold as well as hot climates. This explains why, in one of the various layout proposals, all the yacht’s spaces have been made accessible without the need for guests to go through the external areas. The aft area, for instance, could be accessed through a corridor located on the lower deck that goes through the engine room space—a very good solution for extreme climates.


The owner will be provided with a yacht that could be ideal for permanent living, both comfortable and safe in all weather. The layout plan offers the guests four double cabins, plus a VIP cabin, while a full deck is entirely dedicated to the owner, with a huge cabin looking forward through big windows and a huge terrace overlooking the bow area. Other details that enrich the project are a luxurious sky lounge, a generous aft deck and a spa pool on the upper deck.


A huge space is given to the crew area, which has been designed in compliance with the latest regulations, and which include a generous under lower deck where all the storage and refrigerated compartments are located.


Equipped by twin MTU 12V 4000 M 63 diesels coupled to conventional shaft lines, the Explorer 57  has a top speed of 16 knots and a cruising speed of 15. With a fuel tank capacity of 129,000 liters, the range is 3,000 miles at 15 knots or 5,500 miles at 13 knots. Maneuvering will be implemented by a bow thruster, and the vessel will be equipped by four zero speed electric stabilizers.


The project also considers the possibility to equip the vessel with diesel electric or hybrid propulsion systems.
