Sailpages Buyer's Take

The Dynamic 4000 is a Danish-built cruising sloop designed by Jan Kjærulff and constructed by Bachs Bådværft between 1985 and 1992. With a displacement of 11464.0 lb and a fractional sloop rig, it represents a solid, traditional cruising platform from the mid-80s to early 90s.

Best for:
This boat is well-suited for coastal and nearshore cruisers who prioritize a comfortable, stable ride and manageable handling over high-performance racing metrics.
Bluewater capability:
With a conservative capsize ratio of 1.76 and a displacement of 11464.0 lb, the Dynamic 4000 exhibits the heavy, stable characteristics necessary for safe offshore passage making.
Comparables:
Comparable vessels include the Beneteau First 36.7 and the Hallberg-Rassy 36, as they share similar production eras, fractional sloop rigs, and a focus on balanced cruising comfort.
