BY45 SPEEDSTER
The BY45 Speedster represents the most performance-driven expression of modern yacht design from BRIZO YACHTS. Defined by its modern stealth profile with an Italian flavour, the BY45 Speedster blends timeless elegance with purposeful aggression. Its sculpted lines, balanced proportions, and purist surfaces create a yacht that is both visually striking but also functional -built for those who demand speed without compromise.
Engineered for owners with a passion for performance, the BY45 Speedster delivers exceptional acceleration, high cruising speeds, and precise handling across all sea conditions. The hull is developed to maintain stability, control, and confidence even at elevated speeds. Owners can select between inboard or outboard propulsion, allowing the yacht to be tailored for maximum speed, efficiency, or a perfectly balanced combination of both.
The design is as functional as it is beautiful. A large aft glass door seamlessly connects the saloon with the aft deck, creating a unified living space that enhances both usability and onboard comfort. The interior can be specified with a sleek, sporty character or a more refined, timeless contemporary atmosphere-each executed with premium materials and meticulous craftsmanship. The forward owner’s cabin features a private dayhead and shower, while the mid cabin provides accommodation for guests for overnight stays making the yacht ideal for fast-paced cruising with family or friends.
The BY45 Speedster embodies both heritage and innovation. Extensive customization options allow owners to define propulsion, layout, finishes, and onboard systems, ensuring each yacht is a unique reflection of its owner’s vision.
