Designed for serious offshore cruising, the Southerly 590 represents the flagship of the renowned Southerly range, a British lineup celebrated for its innovative lifting keel technology. This distinctive feature allows the boat to operate in shallow tidal waters while still delivering the deep-draft performance needed for blue-water passages — a combination that has earned Southerly a loyal following among cruising sailors who refuse to compromise between coastal accessibility and offshore capability. The 590 carries all the hallmarks of the broader Southerly philosophy: a focus on comfortable liveaboard cruising, thoughtful interior arrangements, and the confidence to take on long-distance passages. As the largest model in the range, it is built for experienced sailors with ambitious cruising plans, offering the space and systems typically associated with expedition-level voyaging. Southerly's reputation has been built over decades of British sailboat craftsmanship, and the 590 sits at the pinnacle of that heritage. For buyers researching a substantial cruising yacht capable of everything from navigating shallow anchorages to crossing oceans, the Southerly 590 is a compelling and distinctive choice worth serious consideration.
