The Drabant 27 is a 27foot Danish sailboat drawn by maritime architect Gert Gerlach in the late seventies, with fewer than 100 examples launched. Built primarily by Gesten Glasfiber Bådeværft and also at other yards built at other yards as well, the design was even offered as a homecompletion kit, so finished boats can differ in execution from one hull to the next.

Design and Construction

Both hull and deck are solid fibreglass, and the fin keel is iron rather than lead. The length-to-beam ratio of 2.95 and a 39 percent ballast ratio mark her as a moderately loaded cruiser. The build at multiple yards and the home-completion option mean a buyer should expect variation in fit and finish, since the quality of each boat may vary depending on who assembled it.

Rig and Performance

She carries a masthead sloop rig masthead rig, and the sail-area-to-displacement figure sits at 15.3 with the ISO reference sail, rising to 18.2 with a 135 percent genoa. That places her slightly overrigged — she carries more sail plan than 58 percent of comparable sailboats — which helps explain a Relative Speed Performance index of 69. The theoretical displacement-hull speed for her length is 6.3 knots and the quoted maximum is 6.0 knots. A capsize screening value of 1.97 and a Motion Comfort Ratio of 19.6 to 22.1 place her among moderate racers with tolerable motion, while the wetted surface of about 236 square feet and an immersion rate near 706 pounds per inch describe a boat that responds predictably to loading.

Accommodations

Below, the interior is teak, with a toilet facility and headroom described as near average for the class. The cabin reflects a period Danish cruiser layout rather than a bespoke custom interior, and the near-average standing room suggests a pragmatic weekender rather than a full-time liveaboard.

Ownership and Refits

Because some hulls were sold to be finished by their owners, a used Drabant 27 may show non-standard systems or joinery. The iron keel warrants attention for corrosion, and any home-completed example should be inspected for structural consistency where factory process was absent.

The Verdict

The Drabant 27 is a compact, slightly overrigged Danish cruiser-racer with solid fibreglass hull and deck, an iron fin keel, and a teak interior. Low production and the home-completion history make individual condition the deciding factor more than brand uniformity.

Pros

  • Slightly overrigged masthead sloop with strong sail-area-to-displacement for the size
  • Solid fibreglass hull and deck with moderate ballast ratio
  • Shallow-enough draft to enter most marinas

Cons

  • Iron keel susceptible to corrosion
  • Home-completion examples may vary in quality
  • Fewer than 100 built, limiting fleet support and parts commonality
