Design and Construction
Schumacher’s mid-nineties design pairs a 20-foot waterline-era hull with a ballast ratio of 41 percent and a displacement-length ratio of 170, a figure that categorizes her among light racers rather than loaded cruisers anchor. The bulb fin keel keeps the lead low and the draft between roughly 3.5 and 3.8 feet depending on load, so she can tuck into shallow marinas that deeper keelboats cannot reach. Her length-to-beam ratio of 2.93 and a wetted surface near 129 square feet describe a narrow, easily driven hull whose 406 pounds-per-inch immersion rate means she sits sensibly in the water for her size. The capsize screening value of 2.20 is below the threshold accepted for ocean races, a flat statement of her coastal-and-day sailing intent rather than a deficiency in her intended role.
Rig and Handling
The fractional sloop rig is matched to a sail-area-displacement ratio of 22.94, enough to keep her quick in the breeze she was designed for without demanding a racing crew. Period specifications list jib and genoa sheets at 20 feet with 5/16-inch diameter, a 50-foot mainsheet of the same diameter, and a 44-foot spinnaker sheet — dimensions that confirm a compact, easily managed control layout within reach of a short-handed sailor. Her theoretical displacement-boat maximum speed is 5.5 knots, and the Motion Comfort Ratio of 12.6 places her motion in the firm, responsive band typical of a light racer rather than a soft-riding cruiser. The wetted surface of about 129 square feet keeps area modest, supporting the easy acceleration the numbers imply.
The Verdict
The Alerion Express 20 is a low-production Carl Schumacher design that succeeds as a light, easily driven fractional-rig daysailer with shallow-draft bulb-keel access and a racer-bred weight profile. She is not built for offshore passage work, and her scarcity means a buyer must accept limited fleet support. For the sailor who values a distinctive, designer-specified 20-footer with genuine performance credentials, she is a considered choice.
Pros
- Fewer than 100 built, giving rarity and individuality
- 41 percent ballast ratio and 170 DL-ratio mark her as a light racer
- Bulb fin keel holds draft near 3.5–3.8 ft for marina access
- Fractional rig with SA/D 22.94 suited to short-handed sailing
Cons
- Capsize screening value of 2.20 excludes ocean racing acceptance
