Design and Construction
Tucker's design pairs a wood hull with a bilge-keel arrangement and a masthead sloop rig. The 6.83-foot beam against the 21.33-foot length gives a length-to-beam ratio of 3.12, a narrow-ish proportion that keeps the hull lean without sacrificing the twin-keel footprint. Ballast sits at 600 pounds of iron, which against the 2,060-pound displacement yields the 29 percent ballast ratio. The displacement-length ratio of 186 places her among what reviewers call "moderate racers," and the sail-area-to-displacement ratio of 15.37 shows a rig sized to keep her moving in ordinary breeze. With a theoretical hull speed of 5.5 knots, she is no rocket, but the wetted surface of about 118 square feet and the 2.5-foot draft dependent on load let her dry out or sneak into shallow marinas where a fin-keel boat would ground anchor.
Rig and Handling
The masthead rig carries a 155-square-foot sail plan supported by straightforward running rigging. The jib and genoa sheets are each 21.3 feet long and 3/8 inch in diameter, the mainsheet runs 53.3 feet of the same diameter, and a spinnaker sheet of 46.9 feet rounds out the light-air inventory. Those dimensions describe a boat easily handled by a short crew. The capsize screening value of 2.15 is below the threshold ocean racers accept, and the Motion Comfort Ratio of 13.3 describes a small-boat motion profile rather than a bluewater passage-maker. The immersion rate of 404 pounds per inch is a reminder that every locker and crewmember counts on a hull this size.
Accommodations
At 21 feet with a bilge keel and wooden construction, she belongs to an era of simple overnight accommodation rather than equipped cruising quarters.
The Verdict
The Mystic 21 is a period wooden sloop of restrained size and clear intent: a shallow-draft, twin-keel coastal sailor with a masthead rig and moderate-racer numbers. Tucker's lines and Clark's build suit a sailor who values access to thin water over offshore range.
Pros
- Bilge keels and roughly 2.5-foot draft open shallow marinas and drying anchors anchor
- 29 percent ballast ratio and 15.37 SA/D describe a lively small-boat rig
- Wood hull and simple rigging suit the hands-on classic owner
Cons
- Capsize screening of 2.15 excludes her from ocean racing anchor
- Wood construction demands more upkeep than fiberglass contemporaries
- Simple accommodation limits extended cruising use
