Inconstant was a large wooden full-rigged sailing ship constructed in 1848 at Big Bras d'Or, Cape Breton, Nova Scotia. Built by shipbuilder George Old, known for transitioning from schooners to brigs, Inconstant was among the largest vessels ever built on Cape Breton Island and represented Old's most substantial project. The ship's design featured a robust hull typical of mid-19th-century maritime craftsmanship, though specific measurements are not provided in the source. Initially, Inconstant was sold to owners in London, England, and undertook voyages to Australia, primarily transporting immigrants. Her service record includes these transoceanic crossings before her fate changed in 1851. During a voyage to Australia, she called at Wellington, New Zealand, for water and unexpectedly ran aground, leading to her wreck. The damage was deemed too extensive for the vessel to sail again. The hull of Inconstant was purchased by John Plimmer, a notable Wellington entrepreneur often called "the Father of Wellington." She was transformed into a key maritime structure on the Wellington waterfront, earning the nickname "Plimmer's Ark." The ship's hull was converted into a prominent wharf, serving as one of Wellington's first piers. Its interior was repurposed as a warehouse and auction room, and it also functioned as a bonded customs store. Additionally, the ship served as an immigration pier and housed the office of Wellington's first harbourmaster. A light mounted on the seaward side of the hull became Wellington's first harbour light, symbolizing her significance in local maritime history. Between 1857 and 1860, the hull gradually became landlocked due to waterfront expansion, eventually surrounded by Lambton Quay, Customhouse Quay, and Willis Street. The upper parts of the structure were demolished in 1883, and the lower hull was obscured beneath the first Bank of New Zealand building. Nonetheless, archaeological excavations in the late 1990s uncovered the hull's remains, including a 38-meter section of the bilges. Notably, the remains revealed early Canadian shipbuilding features, such as the use of birch for main timbers and layers of birch bark. The preserved bow of the hull is now displayed under glass with artifacts in the Wellington waterfront arcade, highlighting Inconstant's historic maritime significance.
