About the NAUTITECH 475

Sailpages Buyer's Take

The Nautitech 475 is a fractional sloop catamaran designed by Alain Mortain & Yiannis Mavrikios and built by Dufour, with production records indicating a build year of 1995. With a displacement of 20286.0 lb and a LOA of 47.0 ft, this vessel represents a specific era of French catamaran construction, though the exact total hulls built remains unverified in the available data.

Best for:
This boat suits coastal cruisers and those seeking a spacious, stable platform for relaxed sailing, given its high comfort ratio of 9.32 and fractional rig configuration. It is well-suited for owners who prioritize interior volume and ease of handling over high-performance racing metrics.
Bluewater capability:
With a capsize ratio of 3.67 and a displacement of 20286.0 lb, the Nautitech 475 demonstrates moderate offshore stability, though its single build year of 1995 suggests limited long-term fleet data for extreme bluewater endurance.
Comparables:
Comparable vessels include other mid-1990s French catamarans such as the Lagoon 42 or Beneteau First 47, which share similar fractional sloop rigs and target the coastal cruising market. These boats offer similar beam-to-length ratios and interior layouts, providing a benchmark for space and comfort.
