Design and Construction
The Nimbus 42 was designed in the early eighties by F. Michael Kaufman and Robert A. Ladd anchor, and built by the Swedish yard Albin Marin AB. Both hull and deck are molded fiberglass with no core, keeping the structure straightforward and repairable. With a beam of 12.5 feet against a 41.4-foot length, her length-to-beam ratio of 3.32 gives her more interior volume than half of comparable designs, while the ballast ratio sits higher than 88 percent of similar sailboats and signals a very high ability to resist heeling under sail.
Rig and Handling
She is built with a cutter rig carrying an ISO 8666 reference sail area that yields a sail-area-to-displacement ratio of 17.7, rising to 21.2 with a 135 percent genoa. That places her ahead of 54 percent of similar designs in light-air speed, though the rig itself is slightly undercanvased relative to her peers, with more rig than only 46 percent of comparable boats. The fin keel draws between 1.77 and 1.87 meters dependent on the load, shallow enough for most marina entrances. Under power the calculated maximum is about 6.6 knots against a theoretical hull speed of 7.8 knots. A capsize screening value of 1.80 means that by that formula alone she could be accepted for ocean racing, and her displacement-length ratio of 240 categorizes her among moderate racers, with 58 percent of similar designs heavier.
Accommodations
Inside, the headroom is above average for the class, and the beamy 3.32 length-to-beam proportion translates into a more spacious layout than 50 percent of similar sailboat designs. The Motion Comfort Ratio of 31.4 makes her more comfortable than 58 percent of comparable boats, a figure consistent with the comfort data. An immersion rate of about 265 kg per centimeter (1,489 pounds per inch) describes how heavily she loads with gear and water.
The Verdict
The Nimbus 42 is a thoughtfully proportioned Swedish cutter that pairs a stiff, heavily ballasted hull with a slightly conservative rig. Her numbers suggest a boat that resists heeling well, offers above-average comfort and volume, and remains capable of moderate racing or extended cruising without demanding exotic maintenance. The underrigged sail plan is the one area a performance-minded owner may wish to address.
Pros
- Ballast ratio higher than 88 percent of similar designs, with very high resistance to heeling
- Above-average headroom and more spacious than half of comparable layouts
- Comfort ratio better than 58 percent of similar boats
- Capsize screening value permits ocean-race eligibility by formula
Cons
- Slightly underrigged compared with peer sailboats
- Moderate racer classification rather than bluewater-dedicated
