Southerly 100
Description
The Southerly 100 is a 33.75-foot masthead sloop with a signature lifting (swing) keel, designed primarily by Dick Carter (with Northshore input/credit as Carter/Northshore) and built by Northshore Yachts in Itchenor, UK, from 1983 to 2003. It succeeded the Southerly 95 as part of Northshore’s long-running Southerly range of variable-draft cruisers, with 96 boats constructed in fiberglass. The model emphasizes “go-anywhere” shallow-water capability combined with respectable offshore performance, featuring a heavy aerofoil-shaped cast iron lifting keel (electrically or hydraulically operated) and a grounding plate, allowing it to dry out upright or access remote anchorages while maintaining good windward ability and stability when the keel is lowered. Key features include a pilothouse option with interior steering on some examples, solid construction for coastal/offshore cruising, accommodations for 5–6, and a practical layout that balances comfort with sailing dynamics—making it a versatile family cruiser popular in the UK and Europe for its ability to navigate shallow estuaries, creeks, and beaches where fixed-keel boats cannot go.
