About This Yacht
RELENTLESS | Stunning German Frers Hylas 56
Arriving Fort Lauderdale in May
RELENTLESS is a beautifully specified and seriously upgraded 2012 Hylas 56, one of the finest examples of this proven bluewater platform to come to market. Built by Queen Long Marine in Taiwan and designed by German Frers, the Hylas 56 represents the sweet spot where offshore capability, refined performance, and luxurious liveaboard comfort all come together. Hylas has long been recognized for combining elegant yacht joinery, true owner customization, and robust passagemaking construction, while Queen Long Marine’s decades-long reputation for quality has made the brand one of the most respected names in serious cruising sailboats. The Hylas marque was established by the Huang family in 1985, with Queen Long Marine founded in 1978, and the builder continues to be known for high-quality, owner-focused yachts produced in-house by an experienced yard in Kaohsiung, Taiwan.
On deck, RELENTLESS immediately stands apart. Her Awlgrip Flag Blue hull was refreshed and polished in December 2025, and she was re-antifouled at the same time, giving her a crisp, turn-key presentation. Her hand-laid Twaron-reinforced GRP hull, vinylester resin construction, and watertight bulkheads speak to the serious offshore pedigree buyers expect from a Hylas. The deck layout is equally impressive, with teak decks and cockpit, upgraded stainless pushpit with integral teak stern seats, extended safety rails to the midship gates, electric Antal winches, electric traveler controls, a custom Whitlock pedestal, and a substantial Simpson electric davit system. This is the kind of deck package that reflects thoughtful ownership and real-world passagemaking intent, not just dockside aesthetics.
Her sailplan and rig package further elevate the offering. New 2024 Elvstrom EPEX mainsail and 140% genoa, along with replaced standing rigging in 2024, put RELENTLESS in rare company among brokerage offerings in this size range. Add in the staysail, asymmetrical spinnakers, carbon spinnaker pole, electric in-mast furling, upgraded running rigging details, and offshore-minded systems like an internal boom preventer and soft running backstays, and you have a yacht equally suited for effortless short-handed cruising or confident passagemaking with a crew.
Below deck, RELENTLESS delivers the warm, custom feel that has always made the better Hylas yachts so desirable. Rich raised-panel teak cabinetry, teak and ebony soles, expanded saloon seating, elegant upholstery choices, thoughtful handholds, added lighting, and beautifully executed owner-driven customizations give the interior a distinctly high-end feel. The three-cabin, two-head layout is ideal for owner-operators who want both a proper aft owner’s stateroom and comfortable guest accommodations. The saloon is welcoming and refined, the nav station is genuinely functional for long-range cruising, and the galley is exceptional, highlighted by generous refrigeration, freezer space, trash compactor, ice maker, and even a custom La Marzocco GS/3 espresso machine with dedicated grinder—an uncommon and memorable touch that says a great deal about how this yacht was conceived and equipped.
Mechanically and electrically, RELENTLESS is outfitted as a serious long-range cruiser. Her 150 HP Yanmar, Northern Lights 9kW generator, Mastervolt inverter/charger system, extensive AGM battery capacity, 782W of Solbian solar, Spectra watermaker, reverse-cycle air conditioning, bow thruster, and excellent fuel and tank management systems all support comfortable, independent cruising. The electronics suite is also first-rate, with premium B&G H3000 instrumentation, Zeus 3S displays from 2022, HALO24 radar, Starlink, Iridium Go, AIS, upgraded security and tracking, and a very well-developed onboard communications network. She is not simply equipped to cruise—she is equipped to cruise well, with the kind of redundancy, integration, and owner usability that experienced buyers immediately recognize.
What makes RELENTLESS so compelling is that she pairs the pedigree of a German Frers-designed Hylas with the meaningful upgrades and outfitting today’s buyers actually want. She has the looks, the systems, the sail inventory, the construction, and the presence to satisfy a discerning sailor seeking a yacht capable of elegant coastal cruising, serious offshore passages, or extended liveaboard life aboard a platform with enduring market respect. For the buyer searching for a late-model Hylas 56 that feels complete, current, and exceptionally well cared for, RELENTLESS deserves very close attention.

Both seating areas were expanded for enhanced comfort, giving the saloon a notably more luxurious and livable feel than many yachts in this class.
Natural warmth from the teak joinery is complemented by upgraded fabrics, carefully integrated lighting, and custom details throughout.

Rich teak cabinetry, a starboard settee, redesigned hanging locker arrangements, and a vanity cabinet all contribute to a refined and highly functional space.
This stateroom is particularly well suited for passagemaking as well, with numerous handholds, lee cloth attachment points, and thoughtful storage integrated throughout.

Located to port, it is secure, highly functional underway, and thoughtfully customized for an owner who clearly valued both serious cooking capability and life aboard at a very high standard. Generous refrigeration and freezer capacity, abundant cabinetry, strong counter fiddles, excellent ventilation, and premium appliances make this a galley that is equally suited to passagemaking, entertaining, or extended liveaboard use.
What truly sets this space apart is the level of finish and customization. Raised-panel cabinetry, owner-designed drawer arrangements, concealed stainless work surfaces, excellent task lighting, and signature Queen Long details all create a galley that feels refined without sacrificing practicality.

Hylas and Queen Long have long been respected for building nav stations that are not merely decorative, and RELENTLESS carries that tradition forward with a custom L-shaped nav desk that is both elegant and exceptionally functional. The outboard-facing chart table, opening computer compartment, deep drawer storage, hinged electronics access panel, and modified return divider make this a workspace that will be appreciated by any owner planning extended cruising or passagemaking.
This area has clearly been configured by an owner who understood the value of safe, practical onboard operations. The electrical panel and generator controls are intelligently arranged for ease of access, while extra AC outlets, dedicated storage, and a custom swing-out chair make the station comfortable and usable for real time spent onboard.

CONSTRUCTION AND KEY FEATURES OF THE HULL AND DECK
HULL
The hull of RELENTLESS was built to the serious standards expected of a true offshore cruising yacht. She features solid hand-laid GRP construction reinforced with Twaron carbon aramid fiber, paired with vinylester resins and isophthalic gelcoat for strength, durability, and long-term resistance to osmosis. A two-layer epoxy barrier coat and tie coat further enhance hull protection and bottom paint adhesion, reinforcing the yacht’s long-range cruising credentials.
Beyond her technical construction, RELENTLESS also presents beautifully. Her Awlgrip Flag Blue hull with white cove stripe was refreshed and polished in December 2025, and the bottom was re-antifouled at the same time. Two watertight bulkheads—one forming a forward collision bulkhead and the other protecting the stern section forward of the lazarettes—add another layer of offshore security that experienced buyers will immediately appreciate.

Owner-driven upgrades throughout the deck arrangement improve safety, function, and ease of use. Extended lifeline and rail arrangements, additional mooring cleats, custom davit bases, a liferaft cradle, dual antenna mounts, and thoughtful anchoring details all reinforce the impression of a yacht that has been equipped by knowledgeable owners for real-world cruising rather than casual seasonal use.

RELENTLESS is powered and equipped the way a proper bluewater cruising yacht should be—with dependable machinery, thoughtful redundancy, and systems chosen to support long-range independence and confident operation offshore. Her 150 HP Yanmar diesel provides the power and reliability expected for a yacht of this size, while key supporting systems such as the generator, shaft seal, bow thruster, watermaker, climate control, and fuel management equipment demonstrate a very high level of owner investment and offshore readiness.
A major strength of RELENTLESS is that her machinery installation goes beyond simple specification and speaks to real-world cruising practicality. From dedicated AGM start batteries for both main engine and generator, to dual Racor filtration, manifold tank selection, a high-output PTO alternator, and a new Clark pump for the Spectra watermaker in 2025, this is a yacht that has been set up to travel well, stay comfortable, and remain self-sufficient for extended periods away from the dock.

ADDITIONAL INFORMATION
BROKER’S COMMENTS
RELENTLESS is the kind of yacht that stands out immediately to an experienced buyer. The Hylas 56 has long been regarded as one of the most capable and elegant bluewater cruising yachts in her class, and this example benefits from the pedigree of German Frers design, the renowned build quality of Queen Long Marine, and an ownership profile that clearly prioritized meaningful upgrades, serious maintenance, and real offshore capability.
What makes RELENTLESS especially compelling is how complete the package feels. The hull presentation, 2024 sail inventory, 2024 standing rigging, premium B&G electronics suite, Starlink, watermaker, generator, solar, bow thruster, upgraded electric winches, and beautifully customized interior all combine to create a yacht that offers both immediate pride of ownership and genuine cruising readiness. She has the warmth and elegance buyers want in a Hylas, but also the systems depth and offshore outfitting that seasoned passagemakers look for when comparing boats in this size and price range.
For the buyer seeking a late-model, high-quality bluewater yacht with true owner-level customization and a serious inventory, RELENTLESS represents an outstanding opportunity.
REVIEWS
The Hylas 56 earned significant third-party recognition when Cruising World named her Best Premium Cruiser Over 55 Feet in its 2011 Boat of the Year awards. In its coverage, the judges said the boat succeeded by taking “tried-and-true ideas” and presenting them in an “exquisite package,” a concise summary of why the model continues to hold such strong appeal among experienced bluewater buyers.
That same editorial review praised the boat’s execution in exactly the areas that matter most to serious cruisers: sturdy construction, robust deck hardware, thoughtful storage, strong systems installation, and accommodations that remain safe and comfortable at sea. In the broader Boat of the Year write-up, the judges concluded, “If it ain’t broke, make it better,” noting that the Hylas 56’s robust winches, ground tackle, storage, and overall fit and finish addressed the needs of serious cruisers exceptionally well.
Cruising World’s technical judge Ed Sherman was especially complimentary about the quality of the build and systems access, writing, “The workmanship is excellent,” and adding that Hylas had done “a magnificent job with the systems installation.” That kind of praise is particularly meaningful on a yacht in this class, where long-term ownership satisfaction is often driven less by cosmetics alone and more by the integrity, accessibility, and execution of the underlying systems.
Taken together, the editorial consensus around the Hylas 56 is clear: this is a yacht respected not for gimmicks or short-lived trends, but for doing the fundamentals exceptionally well. Strong construction, elegant but seaworthy accommodations, high-quality systems, and owner-friendly passagemaking features are precisely what have made the model so enduringly admired in the bluewater market.
