Z 31 Buyer's Guide
Shopping the used Z 31 means looking at a boat built only in 2002, a 31-foot Danish fractional-sloop cruiser designed by CDE Danish Marine Design ApS with development by Johan Larsvall. Her available swing-keel-with-dual-rudders hull and solid wood construction make her a distinctive small-market find, and the fixed-keel version trades shallow-water reach for a sealed bottom. Because so few were made, a viewing is less about comparing trim levels and more about judging one specific hull's condition.
Layouts on the Used Market
The 10.76-foot beam and 30.97-foot length overall are the envelope within which any belowdecks plan was drawn; the swing-keel and fixed-keel versions share the same topside dimensions, so differences come down to keel-trunk intrusion rather than a redesigned interior.
Equipment and Common Upgrades
On the Greek used market where these boats typically turn up, a bow thruster, bimini, swim platform, teak decks, and chartplotter are commonly fitted, with the teak decks and swim platform being the items most worth a close look for wear. A bow thruster and chartplotter together speak to a boat set up for short-handed Mediterranean mooring, while a bimini and swim platform point to warm-water day use. None of these are structural, but teak deck age drives refinishing cost and a thruster tunnel demands its own underwater inspection.
What to Inspect
A buyer's walkaround should focus on the features the sources confirm. On swing-keel examples, exercise the keel lift and check the trunk for swelling or fastener staining in the solid wood hull. With the dual-rudder layout, confirm both spade rudders turn freely and show no hairline hull joint opening. Where teak decks are fitted, probe for softness at penetrations, and on any bow-thruster boat inspect the tunnel for timber distress.
Availability and Buyer's Takeaway
These boats are typically found in Greece. A short pre-survey checklist:
- Confirm keel lifts smoothly and trunk is dry
- Turn both rudders and check hull joints
- Probe teak decks at fasteners
- Inspect bow-thruster tunnel underwater
- Verify chartplotter and thruster function at demo
