The Southerly 420 represents a pinnacle in the evolution of variable-draft cruising yachts, manufactured by the now-defunct Northshore Shipyard in the United Kingdom. Designed by Humphreys Yacht Design, the 420 is a refined iteration of the earlier Southerly 42, featuring a modernized cockpit layout and an improved deck profile. The hallmark of this vessel is its highly sophisticated swing-keel system, which allows the draft to be reduced from a deep-water 8’ 9” (2.67m) to a mere 2’ 9” (0.84m) at the touch of a button. This capability transforms the 420 from a blue-water passage maker into a vessel capable of navigating shallow estuaries or "drying out" on its massive cast-iron grounding plate, a feat few yachts of this displacement can manage.
