1985 Sterling Yachts 155 Motor Yacht

TRIUMPHANT LADY | 155’ Sterling Motor YachtProject 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.

• 3-story atrium with spiral staircase centerpiece
• Elevator servicing guest areas

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.

The main salon offers elevated seating, entertainment systems, and a full-service bar, while a separate circular dining salon provides a formal setting for 8–10 guests.

Accommodations include:

• Full-beam on-deck master suite
• Two queen staterooms aft (one convertible to massage/spa room)
• Additional guest cabins, all en-suite with entertainment systems

Flybridge & Outdoor Living

Outdoor areas are designed for both privacy and entertainment:

• Sundeck with spa pool and lounging areas
• Covered dining for 8 guests
• Multiple sunpad zones forward and aft
• Easy flow between decks via both staircase and elevator access

The yacht’s layout supports both private owner use and high-end charter functionality.

Onboard Amenities & Features

• Elevator servicing guest decks
• Fully equipped gym with cardio & resistance equipment
• Dedicated massage/spa space
• Large selection of tenders and water toys
• Hydraulic swim platform and boarding system
• Entertainment systems throughout

Notably, the yacht also carries multiple tenders and watercraft including jet skis, fishing/diving tender, and towables—making it a true activity platform.

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
