About the GIRO 34
Water ballast: 2X750 liters Rotating, carbon spar. The design was commissioned specifically (and the first 10 were built) for use in the Around Italy race. Sail Area: Main sail 49 m² Genoa 29.5m2 spin. 109.0 m2
The Giro 34 is a fractional sloop designed by Finot / Conq and built by Maxi Dolphin (ITA) in 1999. With a displacement of 8157.0 lb and a LOA of 33.46 ft, this vessel represents a specific era of Italian yacht construction, though the total number of hulls built remains unconfirmed.
- Best for:
- This boat suits coastal cruisers and performance-oriented sailors who prioritize a fractional rig and moderate comfort ratio of 15.18 for day sailing and short passages.
- Bluewater capability:
- With a capsize ratio of 2.22 and a D/L ratio of 97.21, the Giro 34 is primarily designed for coastal cruising rather than heavy offshore bluewater passage making.
- Comparables:
- Comparable boats include other late-1990s European fractional sloops with similar displacement and beam, such as the Beneteau First 343 or Oyster 34, which share similar performance characteristics and rig configurations.
