Vanguard: Hydro Tec presents the evolution of explorers

Hydro Tec introduces Vanguard, the latest evolutionary stage of explorer yachts

With Hydro Tec , he has designed and engineered many over the last 25 years, developing an unparalleled experience and marking evolutionary stages that have entered history.

A recent and sublime example of this is the newly launched Flexplorer by Cantiere delle Marche which clearly shows how a holistic vision is indispensable for combining creativity and innovation, design and naval engineering.

However, this is not enough for Sergio Cutolo who, on the 25th anniversary of the foundation of Hydro Tec , presents an innovative yet feasible concept. It is called Vanguard and represents the latest evolutionary stage of Explorer Yachts.

This 65 m explorer, was born on a displacement platform, which develops a considerable width and which distorts the vertical position of the various decks, creating a bridge “below deck” well above the full load waterline.

The engine room is also repositioned, largely, in the under-lower deck, occupying a minimum space on the lower deck, essentially intended for air intakes only.

The main deck, towards the stern, sees the tender area, covered, with bridge cranes and side doors for the launch of the tenders and the various toys on board; when these are in the water, this area is mostly usable for outdoor activities.

Further on, towards the bow, we will find on the left the galley, with pantry, and on the starboard access to the owner’s suite consisting of a large study, relaxation area, bedroom, with two terraces to starboard and to port and the bathroom/dressing area.

On the upper deck, aft of the technical area, consisting of the bridge, the office and the master’s cabin, we find the large panoramic sky lounge, with an adjoining cinema area and outdoor terrace. On this level, towards the stern, is the helideck.

From a technical point of view, propulsion is entrusted to two MTU main engines, connected, via shaft lines, to two fixed blade propellers, and, in addition, to two electric motors powered by the on-board network.

Electric motors allow speeds of up to about 10 knots in electric diesel mode.

See the World with Hydro Tec’s Stunning Vanguard Explorer Concept

By Victor Baker

Published on December 12, 2020

Founded in 1995, Hydro Tec has been revealing unique and cool superyacht projects for 25 years now, so there are plenty of reasons to celebrate this year. As such, the Italian naval architecture brand keeps true to its dedication and revealed a superb 65-meter explorer yacht concept.

Called Vanguard, a name that was attached to British battleships for more than 440 years, this yacht concept aims to remind you of those iconic vessel. Designed to embody the essence and spirit of the Italian studio in regards to innovation and exclusivity, this sleek yacht looks mighty fine.

According to studio founder Sergio Cutolo, this spectacular explorer yacht was inspired by “a castle in the middle of the sea”, which some of you might know as Mont Saint Michel.

An odd choice if you ask us, but we do know that Vanguard is based on a displacement platform, which distorts the vertical position of the various decks. As such, mobile terraces in correspondence with the guest cabins and large spaces responsible for technical equipment and toys are something that future owners may benefit from.

A choice in configuration enables the yacht to feature an “under-lower deck”, a sophisticated way of saying engine room; but this choice changes the entire layout of the vessel, allowing for more amenities and comfort to be experienced onboard.

As such, the lower deck becomes fully usable while the central part of the beach area is occupied by a large heated swimming pool, with a foldable side that quickly transforms into an extension of the beach area itself if the weather conditions allow it.

On the other hand, the forward area of the lower deck has been chosen for the crew cabins and their canteen.

Meanwhile, the main deck features a large saloon with an adjoining dining room. You’ll also find here the owner’s suite, featuring a large study and relaxation area, an incredibly spacious bedroom, as well as two terraces – bathroom/dressing areas are included as well.

The upper deck is where passengers will find the generous panoramic sky lounge, with an adjoining cinema area and a lovely outdoor terrace. If you’d like to arrive in style the helideck is there to help, allowing passengers to make a grand entry or leave towards exotic destinations whenever they feel like it.

Hydro Tec’s Vanguard Explorer Concept would come with a hybrid propulsion package,including two MTU engines and two electric motors, that allows this yacht to achieve speeds of up to about 10 knots in electric diesel mode. Would you like to explore the world with this yacht?

Vanguard: to “explorer” the world onboard a SPA

Vanguard is a 65-meter-long Explorer Superyacht equipped with hybrid propulsion and a SPA that can be used even in the most extreme weather conditions on the planet.

Released Vanguard’s new renders, Hydro Tec’s twenty-fifth anniversary celebratory project, a design studio always capable of great innovative thrusts, with a particular focus on the beach club, a flexible and usable space even with the planet’s most extreme climatic conditions.

Vanguard includes all the experience in integrated design, gained in over 25 years of Hydro Tec, where creativity, architecture and engineering find maximum expression.

Indoor environments must be in direct communication with the outside; at the same time all outdoor areas must be able to convert to be able to use them even in cold climates. In short, they must be versatile, flexible, suitable for use in all weather conditions.

Vanguard is precisely the result of this modern conception, offering an articulated and flexible lay-out, with an ideal circulation on it, that avoids fixed paths and duplicated areas.

The regulatory requirements have been bent to the architectural needs, emphasizing one of the strengths of Hydro Tec itself, the ability to analyse every project in its entireness, without overlooking any aspect of the design spiral.

“Nowadays, the interiors and exteriors of a megayacht are lived seamlessly, a homogeneous path in which you can not ignore a perfect integration between the various spaces.” says  Sergio Cutolo

Vanguard: the explorer seen from a SPA

This continuity allows, for example, guests to access the Beach Club directly from their cabins, without having to cross the Main Deck or the others exterior decks.

But this explorer superyacht is also a floating spa . In fact, the pool area can be enclosed with sliding glass windows, which gives the possibility to use the pool in both very hot and very cold climates.

The tender area, located on the main deck, is another space adaptable to different life situations; once the tenders heve been launched, in fact, can be turned into a covered terrace, just like the heli-deck .

The wide spaces of this area allows you to embark many tenders and toys, a fundamental feature for an explorer yacht, born with the idea to cruise for long periods without touching land and in areas of the world poorly equipped for traditional yachts.

Vanguard undoubtedly represents a step forward in the concept of superyacht .

Commissioning Our Explorer Yacht Control System

Updated: Oct 19, 2023

Today, we're diving deep into a crucial phase of our latest project: commissioning our explorer yacht's systems. It's a meticulous process, filled with highs, lows, and plenty of steady progress in between. From testing the communications and marine ethernet to fine-tuning the navigation gear, every moment is a step closer to realizing our dream of a high-latitude sailing vessel.

So, whether you're browsing ocean yachts for sale or just fascinated by the world of maritime exploration, grab your sailor's cap, and let's dive right in!

Everyone who ever built a yacht will experience many highs and lows along the way. Those are the memorable instances, but between them lies the humdrum of steady progress. That is where we found ourselves this week, so I'll recap.

Communications and marine ethernet

Vanguard has a commercial-grade monitoring and control system from Praxis automation. Control is limited to engines, steering, and lighting, though most other things are monitored in some fashion.

The backbone of this system is a dedicated and redundant Ethernet, the big brother of a more familiar NEMA 2000 CAN. Ethernet runs between a number of discrete Input/Output gateway and/or ruggedized PLC's to operate various machinery. One of our first actions after launching was to test the integrity of the data communications system, and with luck, Praxis engineers were already in Antalya at the Damen Shipyard. Our first-off installation was about 90% correct, with a few missing connections and one physically broken. An easy one-day fix all around. We also powered up the 24VDC and 240VAC systems to confirm control and navigation gear power. A first cation here was a sniff test, overheating plastic insulation is quite distinct! Once we are fully powered up all connections can be checked with a thermal camera, for now, a nose is good enough.

Furuno Nav gear

We have contracted a single company (OMS) based in the shipyard to supply and install all Furuno navigation equipment with the exclusion of our large X Band radar arrays supplied by Praxis. It is often cheaper to split a purchase like this into parts sourced by price from many suppliers.

Having watched OMS spend three days connecting and commissioning everything, I'm glad we took the route we did. We now have functioning AIS(A), GPS, Sat Com, Fluxgate, Navtex, Sonar, Weather Station, Sat C, Irridium, VHF Radio's, Starlink, Pepwave ......

Grab handles

Appreciating a physical feature from a simple two-dimensional drawing is often difficult. With that in mind, we fabricated six small grab rails before launch. Once on the vessel with a moderate roll, finding the locations where we needed additional security and preventing the crew from gaining momentum between handholds was easy. The principal being that the lifelines should not act as the first line of defense for a stumbling crewmember. Five rails were secured in such strategic areas, leaving one spare.

Fuel system

Fuel is a subject that brings some considerable risks for the more remote locations. Specifically bunkering contaminated fuel will play havoc with any filter system.

To encourage good fuel husbandry we decided that all fuel being transferred would also be polished to the particulate specification as inlet to the John Deere engines. Filtration efficiency is one measure but there is also the need to retain capacity as they block.

The answer here was to select Cummins Fleetguard duplex filtration system as this has a considerably higher capacity (150g/h) than the more typical and equally efficient Racor filters used in similar installations. It's not a low cost option but it does make life more simple going forward.

Any reader wanting a great and practical explanation of fuel filters I'd recommend to Tony Athens of Seaboard Marine HERE .

Lastly, we move on to stability. Vanguard had no fuel or ballast in her hull when launched. The roll period was about 9 seconds, with quite a severe list at the extremities. Her design has water ballast compensation as we consume fuel on passage. Our first action was to fill 4.2T of water in the FWD water tanks. Once these tanks were pressed full, the roll period reduced to about 7 seconds, though we still have some way to go. From Gerr's book on stability (our Bible in this instance), our target is 1-1.1 times the beam, so 5-5.5 seconds. I'd like to understand some subtleties within this better, but that's the simple version. So now the task is to fully understand her "lightship" stability before proceeding further. A minimum 20% fuel reserve would put an additional 2t of fuel in the center tank, so there is plenty of scope to further bring that 7 seconds down. Looking at the draft, we also have the capacity for some permanent ballast up forward, making those FWD water tanks more useful than just for ballast, as we will not need to keep them full.

Onwards and upwards as the saying goes.

Chris Leigh-Jones

I recently had occasion to bump in to shipmate from some 40 years past. Our families shared a common heritage in part as they had involvement with the same ships, two generations ago. SS Elidir, named after a Welsh mountain was my paternal Grandfather's favorite and last berth. Coal fired, triple expansion engine, oil lamps..... How the world has changed in the course of just two generations.
