Southerly 115 Buyer's Guide
Shopping the brokerage market for a Southerly 115 means choosing among roughly two decades of variable-draft cruisers, from Dick Carter's early Series boats to the twin-rudder Mk IV. Between 250 and 300 were built before production ended around 2007, so examples exist in meaningful numbers — but the later Humphreys-influenced hulls differ sharply from the Mk I in steering behavior and ballast.
Layouts on the Used Market
Owner three-cabin arrangements are the more common configuration afloat, though two-cabin versions appear, and ex-charter boats are a frequent sight. The forward over/under berths, port U-settee saloon, and aft near-king stateroom define the interior regardless of layout, with the L-shaped galley to port. Headroom runs limited on these boats, in part because the swing-keel well intrudes into the cabin.
Equipment and Common Upgrades
Power and energy systems on these boats commonly include a bow thruster, heating, and an inverter, while solar shows up less often as an owner upgrade. Navigation is well covered from the factory onward: chartplotter, radar, AIS, and autopilot are commonly fitted, with a life raft often seen. For canvas and sail handling, a dodger is frequent and a furling main usual, but a bimini and electric winches sit at the rarer end. A short-handed setup and dinghy davits are often seen rather than standard.
What to Inspect
The Mk I's single shallow rudder is known to ventilate as the boat heels, so on earlier hulls check for steering wander and any rudder-blade repair history anchor. On a specific boat, look for rust bleeding through primer or barrier coat at the keel trunk and plate, and ask when the cast-iron swing keel and grounding plate were last blasted and epoxied. Original shaft seals used a light-gauge bronze hose barb that becomes fragile — inspect the seal assembly for cracking or weeping at the stern gland. Confirm whether GFCI outlets were retrofitted, since none were original. Light blue gelcoat fades and crazes faster than white, so examine non-white hulls for crazing near the bulwark and deck joint.
Availability and Buyer's Takeaway
These boats turn up across the United Kingdom, United States, Netherlands, Belgium, Germany, and Greece. Before you commit:
- Confirm rudder configuration matches the generation you want
- Inspect keel and plate for rust breakthrough
- Check stern gland bronze barb for fragility
- Verify GFCI outlets were added
- Review gelcoat condition on colored hulls
