About the HARMONY 47 (PONCIN)

Designed by Mortain & Mavrikios and built by Harmony Yachts (Groupe Poncin Yachts) from 2005–2011, the Harmony 47 is a robust fractional sloop with a displacement of 23479.0 lb and a comfort ratio of 25.38. While the exact hulls built count is unspecified, owner reports highlight a strong preference for Yanmar engines and North sails, alongside significant investment in canvas and electronics upgrades.
- Best for:
- This vessel suits experienced coastal cruisers and offshore adventurers who prioritize comfort and protection, evidenced by the high frequency of dodger and bimini installations. Its substantial displacement and beam make it ideal for those seeking a stable, motion-moderating platform for extended passages.
- Bluewater capability:
- With a low capsize ratio of 1.95 and a displacement of 23479.0 lb, the boat is well-suited for offshore cruising, though potential buyers must rigorously inspect the deck core and keel structure to ensure structural integrity for long-range voyages.
- Comparables:
- Comparable to other large European production cruisers from the mid-2000s such as the Beneteau Oceanis 46 or Jeanneau Sun Odyssey 46.2, the Harmony 47 distinguishes itself with a heavier displacement and a more traditional, robust build quality focused on bluewater capability.
