Sailpages Buyer's Take

Designed by Laurent Giles and built by Westerly Marine Ltd. (UK) from 1984–1988, the Konsort 29 Duo is a compact, heavy-displacement cruiser with 108 hulls produced. Its design emphasizes stability and comfort, reflected in a D/L ratio of 266.56 and a Comfort ratio of 24.8.

Best for:
This boat suits coastal cruisers and couples seeking a stable, easy-to-handle package with a focus on interior comfort rather than high-performance racing. Its manageable size and twin keel configuration make it ideal for shallow-water exploration and single-handed sailing.
Bluewater capability:
With a Capsize ratio of 1.99 and significant displacement of 10100.0 lb, the boat offers strong inherent stability and seakeeping ability suitable for protected offshore passages. The twin keel design enhances safety in shallow waters and simplifies beaching, supporting cautious bluewater cruising.
Comparables:
Comparable boats include the Westerly Comet and other Laurent Giles designs from the same era, which share similar heavy-displacement characteristics and traditional cruising philosophies. It also compares to the Hallberg-Rassy 31 for its robust construction and offshore-minded layout.
