About the ALLEGRO 27
Winner of a design competition sponsored by the Koster Class Association (of Sweden? 1965).
Designed by Lars Olof Norlin and built by ACVA-Båt (SWE) from 1967–1981, the Allegro 27 is a compact, full-keel sloop with 350 hulls produced. Its 6504.0 lb displacement and 1795.5 lb ballast provide a stable, comfortable platform for its 26.35 ft LOA.
- Best for:
- This boat suits coastal cruisers and weekend sailors seeking a manageable, trailerable package with a 4.1 ft max draft that allows access to shallow harbors. Its 21.62 comfort ratio indicates it is well-suited for relaxed, motion-moderated cruising rather than high-performance racing.
- Bluewater capability:
- With a low 1.94 capsize ratio and 209.51 D/L ratio, the Allegro 27 is capable of protected offshore passages, though its 14.88 SA/D ratio suggests it is best suited for moderate winds rather than heavy weather bluewater racing.
- Comparables:
- Comparable boats include the Tartan 27 and O'Day 27, which share similar 1970s full-keel designs and displacement characteristics. These vessels offer similar coastal cruising capabilities and interior volume within the 26-27 ft LOA range.
