Overview
The Southerly 57RS is an Ed Dubois lifting-keel sloop from Northshore Yachts, first built in 2011. It was later renamed the Southerly 590 and, in 2020, the Discovery 57S.
Design and Construction
The hull is fiberglass, 58.14 ft overall on a 52.49 ft waterline, with 17.06 ft of beam. Displacement is 58,755 lb with 18,408 lb of ballast (31.33%). Draft runs from 3.51 ft with the keel up to 10.73 ft with it down. The rig is a sloop carrying about 1,624 sq ft.
Buyers Notes
John Neal rates the Southerly range from the 330 to the 590 at 3 of 5, calling them quality-built, attractive and innovative swing-keel yachts. The lifting keel gives shallow-water access, so check the keel pivot, lifting gear and hull stiffening on any survey.
