StellarCAT AL2503 - STELLARPM FOR SALE

The adventurer of the StellarCAT range, this explorer catamaran is built for true globe-trotting. Vast internal volume, a rigorously engineered all-metal structure, and a Lloyd’s-class hull deliver confidence offshore, while its compact, rugged profile shrugs off tough seas. Commanding, elevated sightlines provide exceptional (read: safe) visibility for a 25m motor yacht.

Spanning nearly 12m of beam, the main deck is anchored by a commanding 59m2 salon that floods with natural light, offering an airy, open-plan feel, generous headroom, and multiple customizable interior schemes. A luxury power catamaran with superyacht poise, it blends comfort with practical elegance.

Engineered and proven for top-tier safety, stability, seakeeping, and comfort, it delivers maximum speeds from 19 to 24 knots and cruising ranges from 1700 nm to 2700 nm, depending on propulsion. An optional long-range package with increased fuel capacity is available for extended bluewater passages—perfect for an expedition yacht, long-range cruiser, and 25m luxury catamaran.
