About the Cumulus 28 Albin Sailboat

Designed by renowned Swedish naval architect Peter Norlin and built by Albin Marine from 1978 to 1985, this fractional sloop represents solid Scandinavian craftsmanship with 567 hulls produced during its seven-year production run. The fiberglass construction features a fin keel with transom-hung rudder configuration, delivering responsive handling characteristics typical of Norlin's racing-influenced designs. With a displacement of 7,055 pounds and generous ballast of 2,810 pounds, the Cumulus 28 offers reassuring stability for coastal cruising and weekend sailing adventures. The boat's sail area of 382 square feet provides adequate power in light to moderate conditions, while the SA/Displacement ratio of 16.67 indicates spirited performance without being overly tender. The low comfort ratio of 23.32 reflects a sportier interior layout prioritizing sailing performance over living space. The design's capsize screening formula of 1.94 and substantial ballast-to-displacement ratio make it well-suited for coastal waters and protected offshore passages. Hull speed reaches 6.33 knots, typical for this length, while the modest 12-horsepower auxiliary engine provides reliable backup power. This model appeals to sailors seeking a responsive, well-built coastal cruiser with European pedigree and proven seaworthiness.
