ER 110 | Untouchable
Length: 110.0 m I Beam: 17.0 m I Draft: 4.4 m
A 110-meter expression of sculptural elegance, contemporary luxury, and true oceangoing capability
ER 110 Untouchable is a 110-meter megayacht project conceived around timeless proportions, sculptural surfaces, and an uncompromising connection with the sea.
Rather than relying on extreme styling or short-lived design trends, Untouchable derives her presence from balance, clarity, and carefully controlled form. Long horizontal lines, sweeping deck overhangs, and uninterrupted bands of glazing create a profile that is calm and elegant, yet unmistakably powerful.
Her architecture develops progressively from the strong, near-vertical bow toward a series of expansive aft decks. Each level forms part of a continuous composition, with the superstructure flowing naturally into the exterior living spaces.
The result is a yacht that is commanding without appearing aggressive, extravagant without excess, and contemporary without compromising her long-term appeal.

Developed Beyond a Conventional Concept
Untouchable has been developed considerably beyond the level of a typical preliminary concept.
A comprehensive three-dimensional model defines the principal hull and superstructure geometry, exterior surfaces, and architectural relationships throughout the yacht. Developed general arrangements, preliminary technical specifications, and propulsion studies provide a credible foundation for further customization, engineering, and shipyard development.
This level of definition allows prospective owners and shipyards to consider the project not simply as a visual proposal, but as a technically considered platform ready to progress toward construction.
The yacht is intended to be built with a steel hull and aluminum superstructure, combining the structural strength and seakeeping characteristics required for extended cruising with the weight savings appropriate for a yacht of this scale.

Architecture Shaped Around the Sea
The relationship between the interior, exterior decks, and surrounding water is central to the design.
Expansive floor-to-ceiling glazing extends along the principal guest decks, bringing natural light deep into the yacht while maintaining panoramic views. Sculpted deck edges provide shade and privacy while reinforcing the yacht’s strong horizontal architecture.
The exterior decks are conceived as natural extensions of the interior. Generous circulation, uninterrupted sightlines, and layered terraces create a seamless transition between formal entertaining, private relaxation, and open-air living.
The expansive foredeck offers a particularly private exterior retreat, while the upper decks provide multiple settings for dining, lounging, and larger social occasions.
A Multilevel Waterfront Experience
The aft section of Untouchable is conceived as one of the yacht’s defining lifestyle environments.
Rather than creating a conventional enclosed beach club, the design establishes a multilevel waterfront destination extending from the main aft deck to the swim platform.
A large swimming pool forms the centerpiece of the upper terrace, framed by broad stairways descending toward the water. Below, the main beach club opens directly onto the swim platform and incorporates a full-service bar, lounge areas, and extensive spaces for relaxation and entertainment.
Large fold-down hull-side terraces extend the usable platform over the water and open the beach club laterally to the sea. When deployed, they transform the stern into an expansive waterfront environment for swimming, sunbathing, socializing, and direct access to tenders and water toys.
The Main Salon
The main salon is conceived on an impressive scale, with panoramic glazing, generous seating areas, and a clear central axis leading toward the formal dining space. Despite its volume, the atmosphere remains welcoming and residential rather than overly formal.
A Private Spa Environment
The owner’s bathroom is arranged as a private spa environment, with symmetrical vanities, a central freestanding bathtub, and a direct visual connection with the surrounding seascape.
Throughout the yacht, the interior and exterior are conceived as a single coherent composition. Materials, proportions, sightlines, and lighting are coordinated to create a continuous experience from the principal salons and private suites to the open decks and waterfront spaces.

“With Untouchable, we wanted to create a yacht that does not depend on fashion or visual tricks. Her character comes from proportion, surface, and the way each deck flows into the next. She is powerful but calm—and the longer you look, the more detail you discover.”
Ivan Erdevicki
Founder and Principal Designer, ER Yacht Design
Aviation and Long-Range Capability
Untouchable is conceived for owners who wish to travel extensively and operate with a high degree of independence.
A dedicated helicopter deck is integrated into the aft section of the upper deck and is designed to support certified helicopter operations, subject to final engineering and approval by the relevant flag-state, classification, and aviation authorities. The proposed arrangement also incorporates onboard helicopter refueling and defueling systems for private transfers and operations in remote cruising areas.
The proposed propulsion concept combines a hybrid diesel-electric shaft-line arrangement with controllable-pitch propellers, Promas propeller-and-rudder systems, and PTI/PTO capability.
The configuration is intended to provide efficient operation across a broad range of speeds and load conditions, together with enhanced maneuverability, operational flexibility, and reduced noise and vibration.
Preliminary performance objectives include a cruising speed of approximately 17 knots and a range of more than 8,500 nautical miles, subject to final naval architecture, displacement, machinery selection, and tank-capacity development.
A Fresh and Contemporary Interior
The interior continues the exterior design philosophy through calm proportions, sculptural detailing, and a restrained yet unmistakably luxurious material palette.
Light-toned natural woods, soft ivory textiles, stone surfaces, and warm metallic accents create a fresh contemporary atmosphere throughout the principal guest areas. Carefully integrated indirect lighting emphasizes the architecture without overwhelming the spaces.
Formal Dining
The dining room combines a sense of occasion with uninterrupted views of the sea, creating a refined setting that remains closely connected to the surrounding environment.
The Owner’s Suite
The owner’s suite offers a softer and more private interpretation of the same design language. A full-width sleeping area, private lounge, and expansive glazing create an open yet intimate retreat.
A Modern Gentleman’s Yacht
Untouchable is not conceived as a design statement for a single moment.
Her identity comes from the strength of her proportions, the refinement of her surfaces, and the balance between beauty, comfort, and serious technical capability.
She is a modern gentleman’s yacht: confident but composed, luxurious but considered, and powerful without sacrificing refinement.
With her advanced level of development, expansive waterfront spaces, aviation capability, and long-range cruising potential, ER 110 Untouchable provides a compelling foundation for further customization and collaboration between a discerning owner, ER Yacht Design, and a leading yacht builder.
