Freshwater Kept, Heated Indoor Stored, Original Owner — The Most Lightly Used Hylas 56 On the Water
Stella Blue is an extraordinary example of the Hylas 56 is undoubtably the most lightly used yacht of her kind available today. Offered for sale by her original owner, she has spent her entire life in freshwater, typically commissioned for only three months each year and stored indoors in a heated facility for the remainder of the season.
Each winter, Stella Blue has been stored with the rig removed, protecting the mast, standing rigging, deck hardware, canvas, and exterior finishes from prolonged exposure to the elements. This exceptional ownership and storage history is evident throughout the yacht. Her exterior, interior, machinery spaces, and bilge all present in remarkably immaculate condition, and there is none of the saltwater corrosion commonly found around stainless-steel hardware, electrical connections, machinery, plumbing components, or deck fittings.
Her condition alone places Stella Blue in a category of her own, but it is the underlying design and construction of the Hylas 56 that makes her such a compelling offshore yacht.
The Hylas 56 is a serious bluewater cruising design created to combine offshore strength, dependable systems, secure handling, and refined liveaboard comfort. Her center-cockpit configuration provides a protected working environment on deck while creating space below for a private and exceptionally spacious aft owner’s suite.
The hull is constructed using hand-laid Twaron carbon-aramid fiber and fiberglass laminates with vinylester resin in a solid, uncored composite structure. This robust construction is complemented by a watertight collision bulkhead forward, watertight aft compartments, a solid lead keel, substantial stainless-steel keel bolts, and a partially skegged rudder positioned above the keel plane for added protection in the event of grounding.
On deck, the Hylas 56 is arranged for safe and efficient offshore operation. High stanchions, double lifelines, substantial stainless-steel and teak handrails, wide side decks, and a deep center cockpit provide security for crew moving around the yacht underway. Generous topside storage includes large aft lazarettes, a stern garage, a deep forward sail locker, and divided anchor and deck-gear compartments.
The cutter rig provides a versatile and manageable sail plan well suited to short-handed cruising. Stella Blue is further distinguished by her electric in-mast furling mainsail, roller-furling headsail and staysail, electric primary and secondary winches, and bow thruster. These features make sail handling, docking, and close-quarters maneuvering significantly easier for a cruising couple or limited crew.
Below deck, Stella Blue offers a highly customized three-cabin, two-head arrangement finished in handcrafted teak with raised-panel cabinetry, bamboo cabin soles, generous storage, and nearly seven feet of headroom in the main saloon. The full-length passage galley provides secure bracing on either tack, while the dedicated navigation station creates a practical command center for offshore passagemaking. The center-cockpit layout also allows for a spacious aft owner’s stateroom with centerline queen berth, extensive hanging lockers, and ensuite head.
For a buyer seeking a Hylas 56 without the wear, corrosion, and accumulated deterioration typically associated with a yacht of this age, Stella Blue represents a rare opportunity. Her original-owner provenance, freshwater history, limited seasonal use, heated indoor storage, immaculate condition, and highly desirable cruising specification set her apart from virtually every comparable Hylas 56 on the market.
