Bertram Sport Fly 25 – The Compact Icon That Set the Standard
The Bertram Sport Fly 25 was created in the early 1970s in response to the growing demand for compact yet high-performance boats, capable of combining cruising comfort with a sporty soul. Designed following the success of larger Bertram models, this 25-footer quickly became a benchmark for those who desired the unmistakable style of the American shipyard in a more accessible and versatile version.
Characterized by the solid and aggressive lines typical of Bertram, the 25 maintains intact the construction philosophy that made the brand famous: a deep V-hull, great stability while cruising, and excellent seaworthiness even in challenging conditions. Despite its compact dimensions, the design is intended to guarantee safety and reliability, qualities that still today make it a model sought after by collectors and enthusiasts.
The sporty flybridge is one of its most appreciated features: a raised second helm station that allows for total visibility and gives the helmsman the feeling of dominating the sea, without sacrificing the practicality of the lower helm. This dual configuration makes it ideal for both sport fishing and family cruising, adapting to various cruising styles.
The interior spaces, compact yet functional, reflect the shipyard’s pragmatic approach: well-distributed spaces, robust materials, and clever solutions that optimize every centimeter. A cabin with convertible berths is located forward, while the small head and galley area make the vessel suitable for short cruises as well.
From a technical standpoint, the Bertram Sport Fly 25 was offered with various engine configurations, both sterndrive and inboard, always capable of ensuring good performance and contained consumption. Its versatility and potential for customization have made it a popular choice in many markets, from Europe to the United States.
Today, the Bertram Sport Fly 25 represents much more than a vintage boat: it is a genuine piece of nautical history, still capable of conveying that unique blend of reliability, sporty elegance, and timeless charm that made the Bertram name a legend at sea.
