About the DEAN 400

Sailpages Buyer's Take

The Dean 400 is a South African-built catamaran designed by Peter Dean and constructed by Dean Catamarans (RSA), with production records indicating a build year of 1995. As a fractional sloop rig with a displacement of 18520.0 lb and a beam of 23.67 ft, it represents a specific era of performance-oriented multihull design.

Best for:
This vessel suits coastal cruisers and offshore travelers seeking a wide-beamed, stable platform with ample interior volume, particularly those interested in self-sufficiency given the high prevalence of watermaker and solar panel installations.
Bluewater capability:
With a low capsize ratio of 3.58 and a displacement of 18520.0 lb, the Dean 400 demonstrates strong offshore stability and seaworthiness, supported by owner reports of extensive bluewater upgrades like watermakers and robust anchoring systems.
Comparables:
Comparable boats include other late-1990s performance catamarans such as the Lagoon 400 or Fountaine-Pajot models, which share similar fractional sloop rigs and target the same market of bluewater cruisers prioritizing speed and comfort.
