Overview
The Southerly 420 is a Rob Humphreys swing-keel sloop built by Northshore Yachts, first built in 2010. It later became the Southerly 430.
Design and Construction
The hull is fiberglass, 42.19 ft overall on a 36.45 ft waterline, with 13.22 ft of beam. Displacement is 26,014 lb with 7,782 lb of ballast (29.91%). Draft runs from 2.76 ft with the keel up to 8.92 ft with it down. The rig is a fractional sloop carrying about 785 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.
