Lagoon 420 Owners Version
A rare opportunity to acquire a three-cabin owner's version Lagoon 420, Sea Dragon presents in excellent condition and has been extensively upgraded for comfortable, trouble free offshore cruising. Originally launched in 2009, this vessel has seen light private use from new and has clearly been cherished throughout her life.
Purchased in 2023 through our brokerage, the current owner sailed Sea Dragon back to Australia and completed a major refit in Townsville in 2024, preparing her for extended bluewater cruising.
Performance is enhanced by a taller mast, providing enjoyable sailing in lighter winds and improved performance across all points of sail. When the sails are down, her upgraded 54hp Yanmar engines (installed 2013) deliver smooth, reliable power.
