Sailpages Buyer's Take

The Delphia 40.3 is a modern cruising yacht designed by Andrzej Skrzat and built by Delphia Yachts, with production records indicating a build year of 2015. While the exact total hull count is unspecified in the available data, the model is characterized by a fractional sloop rig and a displacement of 18960.0 lb.

Best for:
This vessel suits coastal and offshore cruisers seeking a comfortable, stable platform with a high comfort ratio of 25.83, supported by a robust fractional sloop rig and ample interior volume.
Bluewater capability:
With a low capsize ratio of 1.94 and a displacement of 18960.0 lb, the Delphia 40.3 demonstrates strong offshore stability and seakeeping characteristics suitable for bluewater passages.
Comparables:
Comparable boats include other modern European cruising yachts from the mid-2010s with similar displacement and fractional rigs, such as the Beneteau Oceanis 40.1 or Dufour 405, which offer similar performance-to-comfort trade-offs.
