About the BENETEAU 34.7
Shallow Keel draft: 1.65m / 5.42ft
The Beneteau 34.7 is a performance-oriented cruising sloop designed by Farr Design and built by Beneteau (USA) in 2006. With a displacement of 9700.34 lb and a fractional sloop rig, it offers a blend of speed and comfort, though the exact total hulls built remains unspecified in available records.
- Best for:
- This boat suits coastal cruisers and active weekend sailors who prioritize sailing performance and modern ergonomics over heavy bluewater expedition capabilities. Its fractional rig and relatively light displacement make it responsive and easy to handle for couples or small families.
- Bluewater capability:
- With a capsize ratio of 2.08 and a displacement of 9700.34 lb, the 34.7 is suitable for protected coastal passages and short offshore trips, but its light displacement and fin keel suggest it is not optimized for heavy-weather, long-range bluewater voyaging.
- Comparables:
- Comparable boats include the Beneteau 343 and 34.7's predecessor, the Beneteau 34, as well as the Hunter 340 and O'Day 34. These vessels are similar in length and era, offering fractional rigs and cabin layouts designed for comfortable coastal cruising with good interior volume.
