Design and Construction
Groeneveld's hull form gives the Miracle 20 efficient, hydrodynamic hulls paired with elongated dagger boards that bite deep for lift and lateral resistance efficient, hydrodynamic hulls. The structure is a fiberglass and foam sandwich, a light yet stiff layup that keeps the weight low enough for the cat to plane and accelerate hard. The 250-square-foot sail plan sits on a 29-foot-6-inch mast driving a powerful, high-aspect ratio rig that rewards athletic crew work. With a capsize ratio of 4.61 and a displacement-to-length relationship that favors quickness over load carrying, the boat is unambiguously a racer.
Rig and Handling
The Miracle 20 delivers maximum power and acceleration with exceptional handling, a combination that flows from the high-aspect sail plan and the deep dagger boards working together maximum power and acceleration with exceptional handling. Standard equipment includes a colored Mylar race-ready mainsail, a white tri-radial Dacron jib, and a furling jib, all managed through Harken blocks. A Comptip mast adds a measure of safety and preserves performance in high wind, while the double trapeze system lets both crew get their weight outboard for righting moment. Owners could specify an optional spinnaker rig and a roller furling jib for varied downwind and short-handed conditions.
Accommodations
There are no cabins or berths to speak of on a 420-pound racing cat; the Miracle 20 is a day racer for a crew of two. The beamy 8-foot-6-inch platform and kick-up rudders exist to make beaching and righting straightforward rather than to enclose living space. White hulls with colored graphics came standard, with colored hulls available as an option for those wanting a distinct look on the starting line.
Equipment and Standard Features
From the factory the boat arrived fully loaded for club racing: adjustable kick-up rudders for easy beaching, Harken blocks, double trapeze, and the composite Comptip mast adjustable kick-up rudders for easy beaching. The sail inventory alone — Mylar main, tri-radial Dacron jib, and furling jib — shows the intent. Optional Hobie Cat sail colors and colored hulls let an owner personalize the platform without altering its character.
The Verdict
The Miracle 20 is a purpose-built racing cat that asks for competent, athletic sailors and repays them with acceleration and handling few 20-foot cats can match. Its foam-sandwich construction and deep dagger boards make it a serious one-design contender, not a casual beach toy.
