Granada 31 Sailboat Review, Specs, and Listings

Design and Construction

The Granada 31's hull and deck are solid fiberglass, but the hull itself is a balsa-cored sandwich, a detail that shapes both her interior comfort and her long-term care. That balsa core insulates against cold water and cuts condensation below, giving the cabin an indoor climate the design records describe as improved over a single-skin hull sandwich construction improves the indoor climate. The interior joinery is teak, the headroom is above average for the size, and the iron fin keel carries a 40 percent ballast ratio — just below the average for comparable designs, which the numbers suggest leaves her ability to resist heeling a touch under par. The 10-foot beam and 3.08 length-to-beam ratio place her roomier than 58 percent of similar sailboats, a consequence of that beamy midsection rather than any illusion of volume.

Rig and Handling

She is built with a masthead rig carrying 41.2 square meters of mainsail and jib area, and the standing and running rigging follow period norms: halyards run 29.6 meters at 10 mm, sheets 9.4 to 23.5 meters at 12 mm. The sail-area-to-displacement figure sits at 15.3 with the ISO reference sail and 18.1 with a 135 percent genoa, which the design data reads as slightly underrigged and faster than only 38 percent of similar boats in light wind. Yet her Relative Speed Performance of 62 puts her ahead of 62 percent of comparable designs overall, and the theoretical hull speed is 6.6 knots against a calculated 4.4 under the optional Volvo Penta MD7 diesel. The fin keel draws between 5.74 and 6.04 feet depending on load, enough to settle her into most marinas while the spade rudder and 268 displacement-length ratio mark her as a moderate racer rather than a slug.

Accommodations

Below, the Granada 31 is equipped with six berths, a galley, and a toilet facility, laid out under that above-average headroom and finished in teak. The 100-liter fresh water tank and 50-liter stainless steel fuel tank support coastal cruising without constant replenishment, and the cabin's dry warmth — a direct product of the balsa sandwich — makes her a credible shoulder-season boat in northern European waters.

Known Issues

Because the Granada 31 was also sold to be home-completed, the quality of any individual boat may vary widely from a factory-finished example. The balsa-cored hull demands special care wherever the sandwich is penetrated, since any path that lets water reach the core will eventually rot it, and a rotted balsa core is costly or irreparable once saturated. A buyer or owner should treat every through-hull, fastening, and deck fitting as a potential water-ingress point to that core.

Refits and Ownership

The optional inboard is the Volvo Penta MD7, a 13-horsepower diesel turning a saildrive and good for roughly 4.4 knots maximum under power. The 13-gallon fuel capacity is modest, suiting a boat whose sailing performance is the draw rather than long motoring legs. The home-completion history means some hulls will have owner-fitted systems of unknown provenance, so any refit plan should begin with verifying what was factory work and what was not.

The Verdict

The Granada 31 is a thoughtfully engineered small Danish cruiser whose balsa-cored hull delivers real cabin comfort and a roomy beam for the length, backed by a credible performance envelope and a known production run. The home-completion option and the vulnerable core are the caveats: survey any example for water intrusion and verify the build provenance before committing.
