Broker Overview

As a senior broker at Yacht Access, I've seen countless vessels, and the 1985 Sterling 155 Motor Yacht, 'Triumphant Lady', presents a unique proposition for the discerning buyer. This is a substantial 155-foot superyacht, a true project opportunity, not a turnkey vessel. Located in Miami Beach, FL, this Sterling yacht offers a rare entry point into the 150-foot plus market, particularly for those with the vision and resources to complete a refit.

Built by Sterling Yachts and designed by the iconic Jon Bannenberg, her pedigree is undeniable. Bannenberg's influence is evident in her dramatic three-story atrium, a feature that provides an unparalleled sense of volume and grandeur, even by today's standards. This is not a 'cookie-cutter' yacht; it's a vessel with character and a history, offering a canvas for significant customization. The market positioning is clear: this is a value-driven acquisition for a large-volume superyacht, providing a platform for either private enjoyment or a strong charter program, leveraging her proven history in the Caribbean, Bahamas, and Florida.

Construction-wise, the Sterling 155 features a GRP hull and superstructure, a robust build for her era. While she is a 1985 build, the underlying structure is sound, often referred to as having 'solid bones' in the industry. Her hull design, typical of Bannenberg's work, prioritizes volume and seaworthiness, providing a stable platform for extended cruising. She has a beam of 26'6" and a draft of 7'6", indicating a substantial vessel with good internal space.

Propulsion comes from twin Caterpillar 3512TA engines. These are workhorse engines, known for their reliability and serviceability, and are currently running. While specific hours and recent service records would be critical during a survey, the fact that the machinery is operational is a significant advantage for a project yacht of this scale. Performance is respectable for a yacht of her size and age, with a cruise speed around 12 knots and a maximum speed of approximately 14.5 knots, offering efficient long-range capabilities.

The interior layout is one of 'Triumphant Lady's' strongest selling points. Beyond the central atrium with its sweeping spiral staircase and elevator access to all guest decks, she offers expansive living areas. The main salon is generous, featuring elevated seating and a full-service bar. A separate, circular dining salon provides a formal setting for 8-10 guests. Accommodations include a full-beam on-deck master suite, two queen staterooms aft (one convertible to a massage/spa room), and additional guest cabins, totaling 5 staterooms for 10 guests, plus dedicated crew quarters for 9. This configuration is highly desirable for both private and charter operations. Notable features also include a dedicated spa/massage room and a gym, amenities typically found on much newer and more expensive builds.

An honest assessment requires acknowledging that this is a project. While the bones are solid and the machinery runs, a full refit will be necessary to bring her to modern superyacht standards in terms of aesthetics, systems, and finishes. This isn't a vessel you'll step onto and immediately embark on a world cruise without significant investment. However, the trade-off is the acquisition cost. For $1,399,000, you are buying a 155-foot platform with an iconic design, proven machinery, and substantial volume. This is an opportunity to create a bespoke superyacht at a fraction of the cost of a new build or a fully refitted vessel of similar size. For a buyer with a clear vision and the right team, 'Triumphant Lady' represents a compelling value proposition in the large yacht market.

Why This Boat Stands Out

  • Iconic Jon Bannenberg design pedigree and massive 155' platform
  • Dramatic three-story atrium with spiral staircase and elevator access
  • Solid GRP construction and running Caterpillar 3512TA engines
  • Exceptional volume and amenities for a vessel of her vintage, including spa/gym
  • Significant value proposition as a project yacht in the 150'+ class

TRIUMPHANT LADY | 155’ Sterling Motor Yacht Project Yacht Opportunity | Solid Bones | Running Machinery Broker Overview TRIUMPHANT LADY is a 155’ pedigree motor yacht designed by the legendary Jon Bannenberg and built by Sterling Yachts, representing a rare opportunity to acquire a large-volume superyacht with strong fundamentals already in place. This is a project yacht with solid bones and running machinery , offering the right buyer a chance to step into a proven platform and bring her to the next level—whether for private use or charter repositioning. Following a prior refit, she retains standout features including a dramatic three-story atrium, elevator access, and expansive guest areas typically found on much newer builds. This is not a cookie-cutter yacht—it’s a value-driven entry into the 150’+ class with real upside. Why This Yacht Stands Out 155’ platform with massive interior volume Iconic Bannenberg design pedigree 3-story atrium with spiral staircase centerpiece Elevator servicing guest areas Dedicated spa/massage room + gym Strong charter history (Caribbean, Bahamas, Florida) 5 stateroom layout for 10 guests + crew of 9 Key Specifications Builder: Sterling Yachts Designer: Jon Bannenberg Year: 1985 (Refit 2009) Length: 155’ (47.25m) Beam: 26’6” Draft: 7’6” Construction: GRP hull & superstructure Engines: Twin Caterpillar 3512TA Cruise Speed: ~12 knots Max Speed: ~14.5 knots Guests: 10 Cabins: 5 Crew: 9 Layout & Interior The defining feature of TRIUMPHANT LADY is her three-level atrium , creating a sense of scale and openness rarely seen even in modern yachts. This central design element connects the main living spaces via a sweeping spiral staircase.

Performance & Capability Powered by twin Caterpillar diesels, TRIUMPHANT LADY cruises comfortably at ~12 knots with a top speed around 14.5 knots, offering reliable long-range cruising capability for the Bahamas, Caribbean, and U.S. East Coast. Broker Note TRIUMPHANT LADY sits in a unique position in today’s market—offering the volume, guest experience, and pedigree of a much larger yacht at a fraction of the replacement cost. For a buyer looking to step into: Charter revenue potential A high-capacity entertaining platform Or a distinctive private yacht with real presence

Expert Review

The 1985 Sterling 155, 'Triumphant Lady', represents a fascinating opportunity. Sterling Yachts, while not a household name like some European builders, produced solid vessels, and the Bannenberg design ensures a timeless aesthetic and excellent sea-keeping for a yacht of this size. Her GRP hull and superstructure provide a durable foundation. Performance with the Caterpillar 3512TAs is reliable, offering a comfortable cruising speed, though fuel consumption will be a factor to manage. The value proposition here is in the platform: a 155-foot superyacht with a strong design lineage for a price that typically buys a much smaller, newer vessel. However, this is explicitly a project. A comprehensive survey is non-negotiable, focusing not just on the running gear but critically on all systems, structural integrity, and the extent of the refit required. The cost of bringing her to modern standards will be substantial, but for the right buyer, the end result could be a truly unique and valuable superyacht at a significant discount compared to new construction.
