About the MIRAGE 30 SX
A lighter weight version of the Kirby 30 but with different deck molding, larger rig, deeper elliptical keel and rudder and more racing oriented cockpit and interior. Only a handful built. Thanks to Charles Lanning for providing photo and additional information.
The Mirage 30 SX is a fractional sloop designed by Bruce Kirby and built by Mirage Yachts Ltd in Canada, with production records indicating a single year of construction in 1985. As a lightweight cruiser-racer with a displacement of 5900.0 lb and a comfort ratio of 15.37, it offers a responsive sailing experience typical of Kirby's performance-oriented designs from the mid-1980s.
- Best for:
- This boat is best suited for coastal cruisers and weekend racers who prioritize speed and handling over heavy-weather stability or long-term liveaboard comfort. Its fractional rig and moderate beam of 10.5 ft make it manageable for couples or small families seeking an active sailing lifestyle.
- Bluewater capability:
- With a capsize ratio of 2.33 and a displacement of 5900.0 lb, the Mirage 30 SX is primarily a coastal cruiser rather than a dedicated bluewater passage-maker, though its robust Kirby design provides adequate stability for protected offshore passages.
- Comparables:
- Comparable boats include the Cal 30 and the O'Day 302, which share similar length overall (30.0 ft) and fractional sloop rigs from the same era. These vessels offer similar coastal cruising capabilities, though the Mirage's lower displacement (5900.0 lb) distinguishes it as a lighter, more performance-focused alternative to heavier displacement cruisers.
