SIGMA 400 – 1994
A characterful sailboat signed by Rob Humphreys, fast and perfectly suited for rapid cruising
Built in 1994 by Marine Projects, the SIGMA 400 is a sailboat designed by the famous British architect Rob Humphreys, known for high-performance hulls and their sailing qualities.
With its 12.27 m length and 3.89 m beam, a 2.29 m draft and a particularly complete rig, this Sigma 400 combines real cruising ability with a sporty temperament.
Its interior layout emphasizes friendliness and autonomy, with three double cabins and seven berths, while preserving the marine and sporty spirit typical of Sigma yachts.
A PERFORMANCE HULL
The SIGMA 400 benefits from a performance-oriented design, while still being suitable for offshore cruising.
• Overall length: 12.27 m
• Beam: 3.89 m
• Draft: 2.29 m
• Polyester hull
• Monohull
• Architect: Rob Humphreys
• Long keel
• French flag
Its design and sail plan make it a particularly interesting boat for owners looking for sailing sensations without giving up the comfort needed for cruising.
A COMPLETE SAIL PLAN
The boat has a set of sails allowing the sail plan to be easily adapted to different sailing conditions:
• Elvström Full Batten mainsail, Mylar/Taffeta, in good condition
• Jib on furling, Mylar/Taffeta, typical condition
• Latticed jib on detachable stay
• Symmetrical spinnaker
• Carbon whisker pole
This configuration offers great versatility, from coastal sailing to more committed passages.
The presence of a detachable stay with a jib is notably a real advantage for sailing in strong wind, while the symmetrical spinnaker allows the full exploitation of the hull's qualities in reaching/ downwind angles.

A SIGMA 400 WITH A MARITIME SPIRIT
This SIGMA 400 brings together the features that made this line famous: a high-performance hull, a versatile rig, a polyester construction and a layout that allows for genuine cruising.
Its sail inventory is particularly interesting, with a Full Batten mainsail, a jib on furling, a jib on a detachable stay and a symmetrical spinnaker.
The recent overhaul of the propulsion system, including a cleaned heat exchanger and exhaust elbow, new stuffing box and new hydrolube bushing, as well as a KiwiProp three-blade carbon propeller, is also an important point to highlight.
The SIGMA 400 is for a sailing enthusiast looking for a 12-meter sailboat that is both fast and seaworthy and truly designed for sailing, rather than just a simple cruising boat.
Its Rob Humphreys pedigree, its complete sail plan, its 2.29 m draft and its navigation equipment make it a particularly interesting sailboat for a fast offshore cruising program or for sailing with a crew.
A boat that keeps the spirit of performance sailing yachts from the 1990s while offering a level of accommodation that allows cruising comfortably.
