About the DELPHIA 31
Hull length: 9.48m / 32.32 ft Swing keel version: draft - 0.45 - 1.65m / 1.48 - 5.41 ft; displacement - 5,200 kg / 11,464 lbs Keel/cb version: draft - 0.75 - 1.65m / 2.46 - 5.41 ft; displacement - 5,200 kg / 11,464 lbs
The Delphia 31 is a fractional sloop designed by Andrzej Skrzat and built by Delphia Yachts, with production records indicating a start year of 2012. While the exact total hull count is not definitively established in the source data, the vessel is characterized by a displacement of 11244.0 lb and a beam of 11.15 ft.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a comfortable, stable platform with a moderate comfort ratio of 22.94. Its fractional rig and relatively light displacement make it accessible for short-handed sailing, though it is not primarily designed for heavy offshore passage-making.
- Bluewater capability:
- With a capsize ratio of 1.99 and a displacement of 11244.0 lb, the Delphia 31 offers moderate stability for coastal passages but lacks the heavy displacement and robust construction typically required for serious bluewater cruising.
- Comparables:
- Comparable boats include the Beneteau First 31 and the Jeanneau Sun Odyssey 31.9, as they share similar fractional sloop rigs, beam widths around 11 feet, and target the same recreational coastal cruising market.
