Published Design Ratios for the Sweden Yachts 42

1. Sail Area/Displacement Ratio: 18.8

  • Less than 16 would be considered under-powered;
  • 16 to 20 would indicate reasonably good performance;
  • Over 20 suggests relatively high performance.

2. Ballast/Displacement Ratio: 40.3

  • Under 40: less stiff, less powerful
  • Over 40: stiffer, more powerful

3. Displacement/Length Ratio: 197

  • Under 100: Ultralight
  • 100 to 200: Light
  • 200 to 275: Moderate
  • 275 to 350: Heavy
  • Over 350: Ultraheavy

4. Comfort Ratio: 29.4

  • Under 20 indicates a lightweight racing boat
  • 20 to 30 indicates a coastal cruiser
  • 30 to 40 indicates a moderate offshore cruising boat
  • 40 to 50 indicates a heavy offshore boat
  • Over 50 indicates an extremely heavy offshore boat

5. Capsize Screening Formula: 1.8

  • Under 2.0 (the lower the better): Better suited for ocean passages
  • Over 2.0: Less suited for ocean passages

Summary Analysis of the Design Ratios for the Sweden Yachts 42

1. A Sail Area/Displacement Ratio of 18.8 suggests that the Sweden Yachts 42 will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.

2. A Ballast/Displacement Ratio of 40.3 means that the Sweden Yachts 42 will stand up well to her canvas in a blow, helping her to power through the waves.

3. A Displacement/Length Ratio of 197, tells us the Sweden Yachts 42 is a light-to-moderate displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer to a degree.

4. Ted Brewer's Comfort Ratio of 29.4 suggests that crew comfort of a Sweden Yachts 42 in a seaway is similar to what you would associate with the motion of an offshore cruiser with good dynamic stability.

5. The Capsize Screening Formula (CSF) of 1.8 indicates that a Sweden Yachts 42 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.

About the Boat:

The Sweden Yachts 42 is a light sailboat that is very stable and stiff with a good righting capability if capsized. It's a fin keel yacht which makes it more maneuverable but like all fin keelers has less directional stability than a similar boat with a long keel.

It is built by the Swedish yard Sweden Yachts and designed by the Swedish maritime architect Peter Norlin together with Jens Östmann in the late 2000s. The Sweden Yachts 42 has two sleeping cabins and four berths, has an easy comfortable motion at sea under sail and is capable of offshore or ocean voyages.

  • The Sweden Yachts 42 is a light sailboat which is a good performer. It is very stable and stiff and has a good righting capability if capsized.
  • The Sweden Yachts 45 is a moderate weight sailboat which is a high performer. It is very stable and stiff and has a good righting capability if capsized. It is best suited as a fast cruiser.
  • The Sweden Yachts 390 is like a more modern version of the Scanmar. She has a relatively slim hull, lead keel and shallow skeg in front of the rudder. She was designed by Peter Norlin and Jens Östmann, over 70 boats being built between 1991 and 2006.
  • The Malö Yachts 370 is a family yacht developed for sailing performance and comfort. Designed by Peter Norlin/Jens Östmann team.
