Southerly 100 Buyer's Guide
Shopping the brokerage market for a Southerly 100 means looking at a Carter-designed Northshore swing-keel sloop built between 1983 and 2003, with 96 examples produced. These are variable-draft British cruisers, and the used fleet reflects both private and former-charter histories that a buyer should weigh before committing.
Layouts on the Used Market
On the used market, four-cabin charter layouts are the more common configuration you will encounter, though both layout types are available. Ex-charter examples are common, so expect higher cycle counts on systems and more wear in the accommodation spaces than a privately maintained boat would show. The boat has six berths, and the swing-keel machinery is integral to the interior volume regardless of layout chosen.
Equipment and Common Upgrades
Well-equipped examples commonly carry heating, autopilot, chartplotter, bow thruster, radar, and a furling main, which together speak to a boat set up for short-handed or cold-weather cruising. Often-seen additions include a life raft, wind generator, dinghy davits, and a short-handed sail-handling setup. Less commonly, you will find spinnaker, hot water, bimini, inverter, electric winches, swim platform, or AIS as owner upgrades. For a buyer, the bow thruster and furling main reduce docking and sail-handling loads, while the wind generator and davits suggest a boat used for extended anchorages rather than marina hopping.
What to Inspect
The keel of the Southerly 100 is iron and the boat is built with a swing keel, so the keel trunk, pivot, and lift mechanism deserve close inspection for corrosion or seizure iron swing keel construction. The hull is solid fiberglass, but any grounding damage should be assessed against the iron keel and its attachment to the hull. The draft range of 2.26 to 2.56 feet under load should be verified against the keel's free movement through its full travel.
Availability and Buyer's Takeaway
The typical markets for the Southerly 100 are the United Kingdom, Ireland, and the Netherlands. When you go to inspect, prioritize keel-trunk integrity, free swing-keel operation, and evidence of charter wear if the history shows ex-charter use. Confirm the presence of the commonly fitted systems — heating, autopilot, chartplotter, bow thruster, radar, furling main — and treat the often-seen safety and energy gear as a bonus rather than a baseline.
- Verify swing-keel travel and iron keel attachment
- Distinguish ex-charter from private histories
- Check for the common heating, autopilot, and bow-thruster fit-out
