Southern Cross 31 Buyer's Guide
Shopping the brokerage market for a Southern Cross 31 means looking at Thomas Gillmer's 1975-designed double-ender built by C. E. Ryder, a cutter with a full keel and outboard rudder. These are first-generation fiberglass cruisers with true double-ender hull character, and the used fleet reflects a boat meant for serious coastal and offshore cruising rather than casual dock-side life.
Layouts on the Used Market
The Southern Cross 31 carries a simple, orthogonal interior layout that prioritizes function, with straight-line spaces rather than angled or convoluted accommodation plan anchor. The hull itself is a true double-ender with a full keel pulled slightly back from the bow and a cutter rig on a short plank bowsprit, so buyers should expect the classic aft cockpit, midship cabin arrangement typical of the type rather than any open-plan modern interior.
Equipment and Common Upgrades
On the used market, autopilots, heating systems, spinnakers, asymmetric spinnakers, radar, and chartplotters are commonly fitted to these boats, reflecting their role as equipped cruisers anchor. For a buyer, that cluster means the boat is usually prepared for extended navigation and cold-weather living without immediate add-ons. The presence of both symmetric and asymmetric spinnakers points to owners who sailed them actively rather than left them static.
What to Inspect
The defining structural point is the hull form: a little forefoot is cut away to improve tacking and maneuverability, so check that area for prior groundings or repair anchor. The cutter rig uses a fixed bowsprit to support the headstay and a fixed forestay at the stemhead, and a boomkin clears the backstay from the outboard rudder — inspect the chainplates, bowsprit attachment, and boomkin for fatigue or rot in surrounding structure anchor. The low sail-area-to-displacement ratio of about 12.6 is inherent, not a defect, but confirms the boat will feel sluggish in light air, so assess rigging and sail condition for any effort to compensate anchor.
Availability and Buyer's Takeaway
Southern Cross 31s are found in the United States. For a shopper, the checklist is straightforward: confirm the forefoot repair history, examine bowsprit and boomkin attachments, verify the orthogonal interior is intact and unmodified, and expect commonly fitted navigation and comfort gear. This is a capable, traditional cruiser best judged on structural honesty and rig integrity rather than speed.
