Cozy Mk IV for Sale — Four-Seat Canard Homebuilt Performance

The Cozy Mk IV is one of the most successful four-seat homebuilt aircraft designs in history — a canard-configuration composite aircraft derived from Nat Puffer's development of the Rutan VariEze and Long-EZ concepts into a practical, comfortable four-seat personal aircraft that delivers speed and efficiency that certified four-seat singles of comparable power cannot approach. The design's front-mounted canard surface, rear-mounted pusher engine, and composite construction combine to produce an aircraft that cruises at 180+ knots on 200 horsepower while carrying four adults in genuine comfort — a combination simply not available in any certified production aircraft at comparable acquisition cost.

Why the Canard Configuration

The Cozy Mk IV's canard layout is not merely distinctive — it is aerodynamically advantageous. The canard provides lift at the front of the aircraft while the main wing provides lift at the rear, and the design is inherently stall-resistant: the canard reaches its critical angle of attack before the main wing, providing a nose-down pitch response that makes the stall mild and easily recoverable. This characteristic makes canard aircraft genuinely difficult to stall in the conventional sense, providing a safety margin that conventional aircraft cannot replicate. The pusher propeller position behind the cockpit means that a propeller strike in an accident is directed away from the crew.

Building and Buying a Cozy Mk IV

The Cozy Mk IV is available as plans — purchasers build from scratch using fiberglass composite materials and the comprehensive builder documentation that Cozy Girrrls (the current plans holder) provides. Builder-completed aircraft available on the pre-owned market represent significant investments of time and skill, and quality varies with builder capability and attention to detail. A thorough pre-purchase inspection by an A&P with composite aircraft experience is essential before any Cozy Mk IV purchase.
