Some superyachts announce themselves from the horizon, all dramatic silhouette and spectacle. ER Yacht Design’s latest concept, a 110-metre project out of Vancouver, goes the other way. It’s built around proportion and restraint, the idea that real luxury reveals itself slowly rather than all at once.

The studio calls it a “modern gentleman’s yacht”: long-range, timeless exterior, expansive interiors, a strong relationship with the sea. It’s understated by the standards of the 100-metre-plus market, but the scale and ambition still put it among the most serious superyacht concepts out there right now.

Less a floating palace, more a controlled environment, built around privacy, movement, and long-distance travel without giving up comfort.

A different idea of grandeur

At 110 metres, Untouchable doesn’t need visual tricks to make an impression. ER Yacht Design used long horizontal lines and broad deck overhangs to keep it low and composed instead. Big yachts tend to look top-heavy once designers start stacking decks. Untouchable stretches horizontally to avoid that, so it reads as long and deliberate rather than just big. The hull is proposed in steel, the superstructure in aluminium, a standard pairing at this scale that keeps the upper structure comparatively light. Extensive glazing runs across the exterior, blurring the line between inside and out.

Founder Ivan Erdevicki has said the goal was to avoid trend-chasing or visual gimmicks. The yacht’s character is meant to come from its proportions and how the decks relate to each other, not from decoration. That’s a notable stance in a design world getting more experimental by the year. The question here isn’t how futuristic a 110-metre yacht can look. It’s how well it can still hold up decades from now.

Architecture that brings the outside in

Interior and exterior stay closely linked throughout. Floor-to-ceiling glazing runs through the main guest decks, pulling natural light deep into the interior and opening up wide sea views. The goal is a yacht that feels less like a set of enclosed rooms and more like one continuous space connected to the water.

Inside, the material palette keeps things quiet: light woods, ivory textiles, stone, warm metal accents. Richness comes from texture and contrast, not ornamentation.

It’s a familiar idea from high-end residential design. Luxury doesn’t need more objects. It needs better surfaces, more light, and rooms arranged with intent. Untouchable just does it at a much bigger scale. The main saloon works as a panoramic social space, with generous seating and a clear sightline toward the formal dining area, so individual rooms feel connected rather than boxed off.

That also just makes sense practically. On a yacht meant for weeks or months at sea, it has to function as a home, not just a set of impressive rooms.

A private owner’s world

The owner’s suite runs the full beam of the yacht, with its own sleeping area, private lounge and spa-style bathroom. Full-beam isn’t just about square footage. At this size, it turns the private quarters into a real retreat rather than another cabin.

That distinction matters more now. The biggest yachts aren’t just built for entertaining anymore. Owners want somewhere to disappear to as well. Untouchable splits the two clearly: big public spaces for entertaining, quieter private ones for retreat, suited to a yacht meant for more than a short Mediterranean run.

The sea becomes the beach club

The stern is probably the most interesting part of the design. Instead of the usual large enclosed beach club, ER Yacht Design put a multi-level waterfront area at the stern, centred on a pool on the upper terrace, built for a more open relationship with the water.

Fold-down terraces extend out from the hull sides, adding usable space over the sea for swimming, lounging, and tender access. It’s not just another amenity. The stern becomes moveable architecture.

Closed, the yacht keeps its clean profile. Open, it becomes a wide waterfront platform. That flexibility matters more every year, since owners want spaces that can shift, formal one evening, watersports the next. Untouchable is built around exactly that.

A foredeck designed for escape

At the other end of the yacht, the foredeck is another kind of private space, an exterior retreat away from the main decks rather than just working deck space. Stern for contact with the sea and social energy, foredeck for solitude and open horizon. Between them, the upper deck handles dining and informal gatherings. That gives the yacht several distinct outdoor spaces instead of one dominant entertaining deck. At 110 metres, that separation matters. The challenge isn’t finding space. It’s keeping the space from feeling repetitive.

Built for distance, not just display

The understated look shouldn’t be mistaken for a lack of ambition. Untouchable is built for long-range cruising: a proposed range past 8,500 nautical miles, cruising speed around 17 knots. That’s not a small detail. It opens up longer passages and more remote destinations, places you can’t count on much infrastructure or support.

Range becomes part of the luxury here. Real independence means not planning every trip around the next refuelling stop. There’s also a dedicated helicopter deck built to support refuelling and defuelling, which makes helicopter transfers practical in remote areas without needing a conventional airport nearby.

The modern gentleman’s yacht

“Modern gentleman’s yacht” could sound like a throwback: mahogany, leather, club-room interiors. Untouchable reinterprets the idea rather than reproducing it. The materials, the glazing, the open layouts are all clearly contemporary. What survives from the older idea is discretion and composed, purposeful design.

Here, being a gentleman’s yacht doesn’t mean old-fashioned. It means confidence without needing to advertise it. The exterior doesn’t shout. The interior doesn’t overload the eye. The capability is real but built into the architecture instead of shown off as a trophy. In a market obsessed with record dimensions and ever more elaborate amenities, that restraint might end up being the most distinctive thing about it.

Designing for longevity

Concepts like this often stay concepts. Untouchable is a design vision, not a delivered vessel, which means it’s free from the compromises a real shipyard, owner brief or budget would impose. But the better concepts still point toward where design is actually heading, and Untouchable points toward more architectural calm.

The yacht is huge, but the design tries to make that feel ordinary. There’s a lot of glass, but it’s there to connect people to their surroundings, not just show off transparency. There’s a beach club, but it’s a transformable stern rather than an enclosed room. The long range fits the same idea: this isn’t just somewhere to stay while cruising. It’s meant to get an owner to increasingly remote parts of the world.

ER Yacht Design’s expanding ambitions

This lands at an interesting point for ER Yacht Design, which has recently shown concepts at other scales too, including the 61-metre Logos and the 40-metre ER 40 explorer. A 110-metre project is a real jump in ambition. At this size, yacht design starts to look more like urban planning: how guests move between levels, how crew stays out of sight, how technical systems coexist with living space. The whole thing only works if none of that machinery is visible to the guest. That might be the hardest kind of luxury to pull off.

A yacht designed to age well

The best compliment for Untouchable isn’t that it looks futuristic, though it clearly does. It’s the emphasis on proportion, horizontal lines, natural materials and restrained detailing, all meant to resist the fast visual cycles that make luxury products feel dated quickly.

The name fits, in that sense. The yacht is meant to stay unaffected by trends, with its identity coming from architecture rather than fashion.

At 110 metres, this could easily have been an exercise in excess. Instead, size takes a back seat to the experience: space, privacy, range, light, access to the sea.

What defines it is how those pieces come together into one idea: a large, capable vessel that doesn’t need to act like a floating monument.
