About
The Nautical Museum in Castletown preserves one of the most remarkable single survivals in Manx maritime history: the Peggy, a rare 18th-century armed schooner-rigged yacht built around 1791 for the Castletown merchant George Quayle, and displayed today in the very boat cellar beneath his former house where she was built and stored for well over a century before rediscovery. Few vessels of this age and type survive anywhere in the world in anything like original condition, making the Peggy a maritime artefact of genuinely international significance rather than merely a local curiosity.
Quayle, a wealthy and eccentric Castletown banker and merchant, built the Peggy both as a pleasure yacht and, reflecting the uncertain waters of the late 18th century, as an armed vessel capable of defending herself against privateers in the Irish Sea. After his death the boat cellar beneath his house was sealed up, and the Peggy remained largely forgotten until her rediscovery in the early 20th century, preserved in remarkably original condition precisely because she had been shut away rather than continuing in use and suffering the wear, alteration, and eventual loss that befalls most working vessels of any age. Her survival is often compared by maritime historians to a time capsule, offering researchers and visitors alike a rare, largely unaltered window into 18th-century small-boat construction and rigging that working vessels of the period, however well documented on paper, simply do not provide.
Beyond the Peggy herself, the museum explores the Isle of Man's wider maritime and seafaring history, including the herring fishing industry, shipbuilding, and the island's long relationship with the sea that shaped towns like Castletown and Peel alike. The museum's setting within Quayle's historic Georgian house and cellar, in the heart of Castletown's compact heritage quarter alongside Castle Rushen, the Old House of Keys, and the Old Grammar School, makes it a natural and rewarding stop on any tour of the island's former capital.

💡 Visitor Tips
- Combine your visit with Castle Rushen, the Old House of Keys, and the Old Grammar School, all within a few minutes' walk in Castletown's historic quarter.
- The boat cellar is reached by steps and can feel enclosed — those with mobility concerns should contact Manx National Heritage in advance.

- The museum is compact and can comfortably be combined with the other Castletown sites in a single day.
- Children under 18 enter free, making this an economical addition to a Castletown heritage day out.
- If visiting several Manx National Heritage sites during your stay, the Heritage Pass offers better value than paying for individual admissions.
Highlights
The Peggy — An 18th-Century Armed Schooner
The museum's centrepiece and namesake attraction is the Peggy, an armed schooner-rigged yacht built around 1791 for Castletown merchant George Quayle, preserved in her original boat cellar beneath his former house.
Few vessels of this age survive anywhere in anything close to original condition, and the Peggy's remarkable state of preservation — a direct result of being sealed away and forgotten for over a century rather than continuing in active use — makes her an internationally significant piece of maritime archaeology as much as a museum exhibit.
George Quayle — Banker, Merchant and Eccentric
The museum tells the story of George Quayle, the wealthy and famously eccentric Castletown banker and merchant who built the Peggy and the house above her cellar.
Quayle's varied interests and activities, including his role in early Manx banking, give the museum's maritime focus a rich human backstory, showing the kind of prosperous, well-connected individual who could commission a private armed yacht in late 18th-century Mann.
The Boat Cellar and Its Rediscovery
The Peggy's boat cellar, sealed up after Quayle's death and largely forgotten for over a century, was rediscovered in the early 20th century — a genuine moment of maritime archaeological rediscovery comparable in spirit, if smaller in scale, to more famous shipwreck finds. The cellar itself, purpose-built to house the boat, is as much a part of the exhibit as the vessel it protects, and interpretation explains the circumstances of the Peggy's long concealment and eventual rediscovery.
18th-Century Naval Threats and Privateering
The Peggy's armament reflects the real maritime dangers of the late 18th century, when privateers and hostile shipping posed genuine threats to vessels in the Irish Sea, particularly during the American War of Independence and the subsequent French Revolutionary Wars. Displays explain this context, showing why even a wealthy merchant's private pleasure yacht might reasonably be built with the capacity to defend herself.
Collections
The Nautical Museum's principal holding is the Peggy, a rare surviving 18th-century armed schooner-rigged yacht preserved in her original boat cellar — one of the most significant maritime artefacts on the Isle of Man. Supporting the vessel itself, the museum holds material relating to her builder and owner George Quayle, including material on his life and Georgian Castletown household, alongside broader maritime collections covering Manx fishing, shipbuilding, and seafaring history.
Model ships, navigational instruments, and interpretation on 18th-century maritime threats including privateering round out a collection that combines a single exceptional object with wider Manx maritime social history.
