M/Y Miss OSB - When Vision Becomes Vessel.

Build & Specifications

Designed by naval architect Charlie Jannace and built by Hugh Saint Boats, the vessel is known for its "wood wrap" aesthetic on a modern hull.

• Construction Material: A fiberglass hull with a specialized wood wrap. Notably, it incorporates a specific type of OSB (Oriented Strand Board) with water-boiled-proof (WBP) glue, an experimental choice intended to showcase the material's durability.
• Dimensions: Although referred to as a "65 Commuter," the yacht was extended to a total length of approximately 71 feet 10 inches (LOA) to accommodate larger engines.
• Propulsion: Powered by twin Caterpillar C32 ACERT 12-cylinder diesel engines, each producing 1,650-1,652 HP.
• Drive System: Features custom Doen waterjets and bow thrusters.
• Performance: It has a cruising speed of 30 knots and a top speed of approximately 47.8 knots.
• Condition: Despite being over 15 years old, the boat has only roughly 94 engine hoursas of 2026.

Miss OSB is a unique custom commuter-style motor yacht built in 2009 for Canadian forest industry mogul Peter Grant. The vessel was named after Grant's core business product, Oriented Strand Board (OSB), and was designed to be the centerpiece of his $100-million lakefront estate on Lake Temiskaming, known as "Grant Castle".

History & Context

• Origin: Commissioned by Peter Grant, the yacht was intended to symbolize his success in the engineered wood industry. It was built in Florida and underwent initial sea trials there.
• The "Grant Castle": The boat was the inspiration for Canada's largest residential construction project--an 85,000-square-foot abandoned mansion designed specifically to house it in an indoor boathouse.
• Following the 2008 global housing market collapse and the subsequent bankruptcy of Grant Forest Products, the estate was never finished.
• Preservation: With no dock available at the unfinished estate, Miss OSB was pulled from the water in 2010 and kept in climate-controlled storage for over 14 years.

This story begins with a visionary Canadian lumber executive, determined to prove the world wrong. His product--OSB--was known in the homebuilding industry as a low-cost plywood alternative, often criticized for swelling when exposed to moisture. The skeptics were loud. So, he did something bold: he built a yacht and wrapped the hull with it. Not just any yacht--a no-expense-spared masterpiece, built to showcase the potential of OSB in the most unlikely and ambitious way imaginable.

In 2007, Peter Grant, founder of Grant Forest Products, commissioned legendary boatbuilder Hugh Saint--a revered name in handcrafted wooden yachts--to build a custom commuter cruiser wrapped in OSB wood. This would be the crown jewel of a planned $100 million dollar lakefront estate in Northern Canada.

But this wasn't ordinary OSB that the hull was wrapped in. Over $3 million was invested in R&D, developing a proprietary method to treat and finish the material using West System Epoxy Resin, transforming structural board into a high-gloss, marine-grade surface that defies belief.

The result: Miss OSB. A one-of-a-kind luxury yacht, powered by twin Caterpillar C32 ACERT 12-cylinder engines pushing a combined 3,300 HP to twin Doen water jet drives. She's fast, clocked at 55 mph and barely used, with only 94 engine hours to date. Construction cost? $10 million. Usage? As close as it gets to none.

Then came 2008, The housing market collapsed and Grant's core business tanked. The estate was never completed. With nowhere to dock her, Miss OSB was pulled from the water in 2010 and placed in climate-controlled storage, where she has remained for the past 15 years.

Now, the story begins a new chapter. Both the abandoned estate and the 2009 Hugh Saint 65 commuter Miss OSB have been purchased by a Texas entrepreneur, who plans to film a docuseries titled "Mansion Impossible". As part of the show's concept, the new owner of Miss OSB must agree to feature the yacht in at least one episode. After all, this boat inspired the mansion--it's the soul of the property's origin story.

The vessel will be sold as-is, with full transparency, and a complete survey available to qualified buyers.

Miss OSB isn't just a yacht. She's a statement--a floating sculpture, born of ambition, risk, and uncompromising craftsmanship. She is a legacy in motion. And now, for the right buyer, she represents a once-in-a-lifetime opportunity to own an irreplaceable piece of Canadian boatbuilding history.
