Intending to pivot from conventional yacht design, HUB has been conceived from the philosophy of prioritising human interaction over formal structure. “HUB is not a reaction against tradition for its own sake,” the designers explain. “It is the product of asking straightforward questions… about what luxury really means when you strip it back to experience rather than appearance.” <img src="https://photo-assets.superyachttimes.com/photo/389554/image/large-1e31f315d7d9ddca4276d6a6e5c7058a.jpg" data-gid="gid://syiq/Photo/389554" style="box-sizing: inherit; border: 0px; font-family: &quot;Open Sans&quot;, sans-serif; position: relative; max-width: 100%; margin: 1rem 0px; color: rgb(0, 0, 0); font-size: 13.6px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Central to the concept is <a data-gid="gid://syiq/Company/5009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lateral Naval Architects (Company)">Lateral</a>’s Free From Bulkheads (FFB) technical platform, where watertight bulkheads stop at the lower deck instead of continuing upward. This approach allows a more open and flexible interior arrangement, unlike a traditional yacht layout where bulkheads run all the way up through multiple decks which result in segmented interior spaces. <img src="https://photo-assets.superyachttimes.com/photo/389556/image/large-174878b32d4b82258f1137c6670cb22d.jpg" data-gid="gid://syiq/Photo/389556">“HUB&nbsp;is a place to be, a nexus of connectivity and expression,” the team says as they describe it as a concept where spaces are designed to “seamlessly blend into one another, fostering an environment of continuous engagement.” <img src="https://photo-assets.superyachttimes.com/photo/389551/image/large-a98539f156a96dd25f416e04212575f9.jpg" data-gid="gid://syiq/Photo/389551">Designed by <a data-gid="gid://syiq/Company/7383" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="byJC (Company)">byJC</a>, her modern exterior profile is reflects this approach with highly adaptable deck spaces. Across her levels, asymmetric layouts are created to encourage movement between her interior and exterior spaces, creating a more homely feel. Her tiered decks feature a beach club where sides open out as platforms, while rotating louvres and curved sliding add flexibility. <img src="https://photo-assets.superyachttimes.com/photo/389553/image/large-c9dff946d4e2f14d694db6baa0c8e71d.jpg" data-gid="gid://syiq/Photo/389553" style="box-sizing: inherit; border: 0px; font-family: &quot;Open Sans&quot;, sans-serif; position: relative; max-width: 100%; margin: 1rem 0px; color: rgb(0, 0, 0); font-size: 13.6px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; background-color: rgb(255, 255, 255);">At water level, her lower deck features a “Beach-Cave”, which is a multifunctional space for a watersports centre and a social lounge. Here, opening hull sides transform into platforms, which aims to reinforce the guests’ connection to the sea.<img src="https://photo-assets.superyachttimes.com/photo/389559/image/large-9ef646e5aedeb668e75b0799e5028ae4.jpg" data-gid="gid://syiq/Photo/389559">With a beam of 13.8-metres and an interior volume of 2,500 GT, her main deck is defined by openness and informality where fluid divisions replace traditional saloon arrangements. Above, her upper deck embodies a more relaxed interpretation of onboard living, featuring a sky lounge and outdoor dining spaces free from rigidity. <img src="https://photo-assets.superyachttimes.com/photo/389558/image/large-477fe9f6f5d48d7937ac34eb9eef3f52.jpg" data-gid="gid://syiq/Photo/389558">Further on her interior design by <a data-gid="gid://syiq/Company/4998" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lawson Robb (Company)">Lawson Robb</a>, HUB is crafted with continuous flow between her social, wellness and relaxation areas in mind. Pale timber tones accentuate the curved furnishings, creating a contemporary and calm atmosphere. Her floor-to-ceiling windows blur the boundary between her interior and exterior spaces while drawing in natural light throughout the yacht. <img src="https://photo-assets.superyachttimes.com/photo/389557/image/large-10de98ab862bbe10ab232cf371a14208.jpg" data-gid="gid://syiq/Photo/389557">In terms of performance, HUB integrates an all-electric hybrid propulsion system, where the batteries serve as the primary energy source, delivering a top speed of 16.5 knots. This configuration enables silent operation, reduced vibration and zero local emissions during certain operating modes. <img src="https://photo-assets.superyachttimes.com/photo/389555/image/large-bb6debe59f495eab0a107a765ab4aec0.jpg" data-gid="gid://syiq/Photo/389555">

Lateral Naval Architects unveils 83m HUB superyacht concept

 Lateral Naval Architects, byJC and Lawson Robb unveil the 83m HUB superyacht concept. 

The Oi60 is a design study for a 63.5-metre sailing trimaran by James Carley of <a data-gid="gid://syiq/Company/7383" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="byJC (Company)">JC Yacht Architecture</a> and <a data-gid="gid://syiq/Company/3009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rob Doyle Design (Company)">Rob Doyle Design</a>. The avantgarde concept builds on the positive reception of another multihull project, the smaller Domus concept with <a data-gid="gid://syiq/Company/1356" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Van Geest Design (Company)">Van Geest Design</a> that we reviewed in the very first issue of How to Build It.<img src="https://photo-assets.superyachttimes.com/photo/336855/image/large-46e88c89e1218ba82678c6f5773c1cf0.jpg" data-gid="gid://syiq/Photo/336855">“I‘ve been sailing much of my life and was intrigued by the whole idea of a world explorer trimaran and being able to cover a lot of ground quickly in a luxurious but sustainable way,” begins James Carley, a naval architect and chartered engineer who honed his design skills at the studios of Martin Francis and <a data-gid="gid://syiq/Company/17" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Bannenberg & Rowell Design (Company)">Bannenberg &amp; Rowell</a>.&nbsp;Carley’s bold exterior design and interior layout for the Oi60 are strikingly, but the basic principles behind the trimaran configuration remain the same. Trimarans are usually wider than catamarans, which means more interior volume and deck space; maximum heel angles of two degrees allow the windward hull to come out of the water for less drag, higher performance and more comfort under way; three hulls in the water are also more stable at anchor with vastly reduced motions compared to a monohull; and unlike a catamaran, all the systems and engineering can be centralised in the main hull, which means fewer structural stresses and deflections – all factors that might persuade owners to switch from power to sail.<img src="https://photo-assets.superyachttimes.com/photo/336840/image/large-3d8c5129c5eb3865b8059cb5cb72937d.jpg" data-gid="gid://syiq/Photo/336840">The armas or outriggers are effectively for buoyancy purposes only and while they can be used for tankage and storage, all the guest accommodation and interior living spaces are concentrated on one level on main deck with the crew quarters and services on the lower deck in the central hull. This makes for a more inclusive onboard experience and vastly improves circulation flow for both guests and crew by avoiding the inconvenience of multiple decks – evident in Carley’s innovative ‘radial’ layout. It also brings cost savings by simplifying the systems design and construction.“Sailing yachts can cost twice as much to build per gross ton as motoryachts,” <a data-gid="gid://syiq/Company/3009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rob Doyle Design (Company)">Rob Doyle</a> points out. “We approached this project by pricing it as if it were a conventional motoryacht with two rigs, but designing outwards instead of upwards. We’ve calculated the volume at over 1200GT, which is equivalent to a 65 or 70-metre monohull, but you get the huge open and semi-open deck spaces that only a trimaran can offer for free, so to speak.”&nbsp;<img src="https://photo-assets.superyachttimes.com/photo/336841/image/large-781abc3c9cb8ae3afc3135cb312fcd07.jpg" data-gid="gid://syiq/Photo/336841">It is no coincidence that the ‘Oi’ in the concept name stands for ‘Outside-inside’. Like Domus, the crossbeam connecting the three aluminium hulls is, in effect, a huge perforated box that offers excellent strength and rigidity. The perforations or cut-outs have been designed around the choice of build material, load paths, boundary conditions and other constraints to offer enormous semi-open areas as well as giant windows, especially in the forward-facing suites. The result is something that could easily double as the villain’s futuristic lair in a James Bond movie.“On the bigger motoryachts with four or five decks, everyone tends to congregate on one particular deck anyway, so why not have it all on one multi-purpose level?” asks Carley. “We can still carve more intimate spaces out of that much bigger space to suit different needs throughout the day. And a lovely change is that we’ve been careful not to be greedy by trying to fill up every square of interior, hence the semi-open areas.”MoonrakerCritical to the whole concept is a feature that is still under wraps. Like Domus, the masts will be Panamax but unlike the earlier concept that had a hoist-able, double-luffed mainsail to achieve some of the efficiency of a wing sail, <a data-gid="gid://syiq/Company/3009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rob Doyle Design (Company)">Rob Doyle Design</a> has devised a new self-supporting, joystick-controlled square rig called the Moonraker (named not after the Bond novel, but the topmost sail on the fastest square riggers of old). <a data-gid="gid://syiq/Company/3009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rob Doyle Design (Company)">Rob Doyle Design</a> claims the Moonraker offers superior performance at less cost and refer to as the Dynarig’s ‘Nokia moment’.<img src="https://photo-assets.superyachttimes.com/photo/336842/image/large-528ca28dc89afe76b515c44e3132731a.jpg" data-gid="gid://syiq/Photo/336842">“We’ve signed an NDA with <a data-gid="gid://syiq/Company/2447" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Southern Spars (Company)">Southern Spars</a> who are undertaking a research program to verify performance and the Moonraker will be officially presented later this year,” says Mark Small. “We’ve been sitting on the Dynarig concept for years, but never got to version two-point-oh and without giving away too much, the critical point about the Moonraker is what the Dynarig can’t do. We hope to achieve downwind performance similar to a spinnakered ketch, which will make passagemaking much quicker. And critically, it will be cheaper to build than an equivalent Dynarig, so basically win-win.“Maltese Falcon and Black Pearl, currently the only yachts launched with Dynarigs, have full-carbon masts and spars. This would not necessarily be the case on the Oi60 and the masts could be of aluminium, since the trimaran has so much righting moment anyway there is less need for a superlight but super expensive high-modulus rig. &nbsp;Team TrimaranJames studied naval architecture at the same time as Rob and Mark at Southampton University and the opportunity to collaborate came when he left <a data-gid="gid://syiq/Company/17" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Bannenberg & Rowell Design (Company)">Bannenberg &amp; Rowell</a> to set up his own design studio. The immediate inspiration for the Oi60 was a YouTube video he saw of a group of freewheeling friends sailing a performance catamaran from Tahiti to Hawaii. James got to thinking how to make long-distance sailing even faster and was initially keen to add foils to boost speed and comfort still further, but was dissuaded by Rob and Mark.“At this size the structures involved would be enormous and if you have a problem with them, you have a very big problem,” says Rob. “We figured it was also unnecessary, because we have loads of performance already at hand and the idea is to make the Oi60 as cost-effective to build as possible. Why would you open the door for that kind of added complexity and cost?”<img src="https://photo-assets.superyachttimes.com/photo/336854/image/large-fd22aac8c606f40d29985389dac21505.jpg" data-gid="gid://syiq/Photo/336854">Given the huge surfaces area the trimaran configuration offers, it makes sense to cover it with solar panels to generate renewable energy. <a data-gid="gid://syiq/Company/3009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rob Doyle Design (Company)">Rob Doyle Design</a> reckons that 300 kilowatt-hour per day could be produced from some 300-square-metres of photovoltaic cells to reduce generator loads for hotel use. Moreover, when sailing the freewheeling propellers can regenerate energy to store in batteries for future use. At hull speed the extra drag makes little difference, but the prop blades can also be folded when performance under sail is a priority.&nbsp;“We’ve calculated that when sailing, the solar cells and regenerative propellers can produce all the energy that's required on board, including HVAC, which will be way in excess of what's actually needed to run the vessel,” says Mark. “It’s a pragmatic combination of renewable and regenerative for what will be a diesel-electric or hybrid diesel-electric boat.”&nbsp;Under the InfluenceAlthough prospective clients have expressed interest in the Oi60 concept, its designers purposely avoided undue influence from owners while developing the concept.“Most owners have preconceived ideas of other boats in their heads,” says Rob. “We wanted to nip that in the bud so we could come up with something new and fresh. James came to us over a year ago with a blank piece of paper and we took our time developing his ideas into something very unique. Sometimes you have to give these creative projects time to develop, so we didn’t rush it or try to mash three or four other boat designs together.”As naval architects as well as designers, all three are well aware of the technical and financial constraints associated with designing superyachts. After all, if the aim is to provide owners and shipyards with solutions that are both new and viable, there is little point in coming up with ideas that are ultimately unbuildable. <img src="https://photo-assets.superyachttimes.com/photo/336853/image/large-885ea3c8bcbf4cc4e0f1831fd3250195.jpg" data-gid="gid://syiq/Photo/336853">“We see a lot of concept projects that can't be built, or they can be built but would cost half a billion to manufacture,” Mark points out. “We always balance the creative with the technical, which also means taking into account factors that may affect the price. We would never have started with the Oi60 unless we thought it made sense.”“I would really love to see it get built,” ends James. “Done right, I think it could be very special.”This article was featured in <a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-7" rel="noopener noreferrer" target="_blank" title="">Issue 7 of How To Build It</a>.

Rob Doyle Design and byJC have unveiled the first renderings for a new 63.5-metre world explorer trimaran concept, Oi60.

Introducing Oi60: The 64m world explorer trimaran by Rob Doyle and byJC

byJC and Hull Studio have unveiled an innovative 68-metre motor yacht concept called JH68 that represents a shift in onboard living, seamlessly integrating adaptable spaces and design elements.<img src="https://photo-assets.superyachttimes.com/photo/290531/image/large-1100dedee0a19422d789b8e82ea29264.jpg" data-gid="gid://syiq/Photo/290531">The core idea behind this project is the notion of adaptability to provide yacht owners and guests with a versatile and dynamic onboard experience. To achieve this, byJC &amp; Hull Studio rethought the conventional approach to yacht design, focusing on the individual furniture pieces and their integration into the yacht's surroundings.<img src="https://photo-assets.superyachttimes.com/photo/290529/image/large-d9ba6388df4a655bbf15d9136b172943.jpg" data-gid="gid://syiq/Photo/290529">Much of the furniture onboard the JH68 can move, rotate, retract, and cross boundaries, creating diverse areas within the vessel. With a plethora of sliding walls and partitions, both internally and externally, the yacht's spaces effortlessly transform, shifting from open-plan expansiveness to intimate and cosy retreats.<img src="https://photo-assets.superyachttimes.com/photo/290751/image/large-f6e4129104633c6d477b58009f72a31c.jpg" data-gid="gid://syiq/Photo/290751"><img src="https://photo-assets.superyachttimes.com/photo/290752/image/large-68f2b36d47a9dfb4322af7eab9d4c0e9.jpg" data-gid="gid://syiq/Photo/290752"><img src="https://photo-assets.superyachttimes.com/photo/290753/image/large-4e2b0061160313b87c1da6af20830ed9.jpg" data-gid="gid://syiq/Photo/290753"><img src="https://photo-assets.superyachttimes.com/photo/290534/image/large-72f2822616da7e54052d8e2aa5804c6f.jpg" data-gid="gid://syiq/Photo/290534">The permeability of the yacht's structure is a crucial aspect of its design. It adapts to suit the prevailing conditions and the preferences of its users. The cleverly engineered sliding walls and partitions enable a seamless transition from one space to another, enhancing the overall comfort and functionality of the yacht.<img src="https://photo-assets.superyachttimes.com/photo/290532/image/large-4883218961fdd8817a7516d3118e8845.jpg" data-gid="gid://syiq/Photo/290532">One notable feature that sets this concept apart is its dedication to natural ventilation. Opening portals direct airflows, ensuring the assorted aft deck spaces are well-ventilated while embracing a timeless cooling process. This sustainable approach enhances comfort and aligns with modern eco-conscious values.<img src="https://photo-assets.superyachttimes.com/photo/290536/image/large-c309b10f8b7de7ac6f379e71a949a291.jpg" data-gid="gid://syiq/Photo/290536">Architecturally, the yacht is divided into two blocks, effectively segregating areas for the crew and the guests. This division minimises crossover, with the crew area concentrated towards the forward section, overseeing operations, back-of-house activities, and the smooth running of the yacht. However, the most coveted real estate is dedicated to the owner and their guests.<img src="https://photo-assets.superyachttimes.com/photo/290530/image/large-e98d2edd355684bf544fa4d3c8bfdecd.jpg" data-gid="gid://syiq/Photo/290530">The penthouse is situated on top of the semi-enclosed aft decks. Intuitively designed staircases connect these spaces seamlessly, creating continuity and fluidity throughout the yacht. This design also serves as a bridge to the surrounding sea and its breathtaking vistas.
