Published Design Ratios for the Hylas 46

1. Sail Area/Displacement Ratio: 20.5

  • 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: 44.5

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

3. Displacement/Length Ratio: 194

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

4. Comfort Ratio: 31.3

  • 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 Hylas 46

1. A Sail Area/Displacement Ratio of 20.5 suggests that, in the right hands, the Hylas 46 will have enough performance to leave most other sailboats of similar waterline length well astern. 

2. A Ballast/Displacement Ratio of 44.5 means that the Hylas 46 will stand up well to her canvas in a blow, helping her to power through the waves. 

3. A Displacement/Length Ratio of 194, tells us the Hylas 46 is a light-to-moderate displacement sailboat, which means she'll carry a reasonable amount of cruising gear without it having much of an effect on her performance.

4. Ted Brewer's Comfort Ratio of 31.3 suggests that crew comfort of a Hylas 46 in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.

5. The Capsize Screening Formula (CSF) of 1.8 tells us that a Hylas 46 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
