The allure of classic wooden boats lies not just in their aesthetic appeal, but also in the stories they carry across time. The 1972 Greavette Sunflash III, an 18-foot vessel crafted by Greavette Boatworks in Gravenhurst, Ontario, embodies this sentiment. With only ten models produced that year, and a mere fifty-two crafted between 1969 and 1972, it represents a rare breed of nautical history.

The heart of any vessel is its engine, and the Sunflash III is no exception. Originally equipped with a 165HP inline-six (I6) engine, many of these boats have since undergone repowering, a process of replacing the original engine with a more modern alternative. One common upgrade involves a 236HP 4.3L V6 engine. This transition not only boosts performance but also enhances the overall driving experience.

Performance metrics speak volumes about a boat’s capabilities. A repowered Sunflash III can achieve a top speed of 54 mph, as measured by GPS. This figure isn’t just a number; it represents the culmination of design and engineering aimed at delivering both speed and stability. The deep V hull design is crucial here, ensuring a smooth and dry ride even when slicing through choppy waters. Some owners have taken performance enhancement a step further by adding lifting strakes to the hull. These strakes reduce hydrodynamic drag, allowing the boat to plane more quickly and efficiently, thereby improving overall performance.

While the 18-foot length is a defining characteristic, precise original dimensions such as beam and draft often require deeper investigation. Original manufacturer documentation, owner records, or historical archives are invaluable resources for uncovering these details. The quest for such specifications is akin to an archaeologist piecing together fragments of the past to reveal a complete picture.

The Greavette Boat Company, based in Gravenhurst, Ontario, holds a significant place in Canadian maritime history. Founded in 1930 by Thomas Greavette, who previously honed his skills at Ditchburn Boats, the company quickly gained a reputation for quality craftsmanship. Gravenhurst itself is a town steeped in boating history, serving as the home port for the RMS Segwun, North America’s oldest operating steamship. This heritage provides a fitting backdrop for the legacy of Greavette boats.

Repowering a classic boat like the Sunflash III is not merely about upgrading its mechanical components; it’s about preserving a piece of history while adapting it for contemporary use. The decision to repower often involves balancing the desire for increased performance with the need to maintain the boat’s original character. This is where the expertise of boat builders and restorers like Tim Butson becomes invaluable. Butson’s work on classic Greavette Executives and Chris-Crafts exemplifies the dedication required to keep these vintage vessels afloat.

The enduring appeal of classic wooden boats lies in their ability to evoke a sense of nostalgia and admiration for a bygone era. The 1972 Greavette Sunflash III, with its blend of classic design and modern enhancements, stands as a testament to the enduring legacy of Greavette Boatworks and the timeless allure of wooden boats. It invites us to reflect on the craftsmanship, innovation, and passion that define the world of vintage boating.
