Design Ratios: The Key Performance Indicators

The design ratios will give a reasonable prediction of how the boat is likely to perform in a seaway, but of course nothing beats a trial sail in various wind and sea conditions.

  • The Sail Area/Displacement Ratio (SA/D) is a measure of the boat's speed potential, and the Beneteau First 375 has a SA/D of 17.8, indicating a good balance between power and stability.
  • The Ballast/Displacement Ratio (B/D) of the Beneteau First 375 is 31.6%, which suggests that the boat has a moderate stability, with enough ballast to keep the boat upright in most conditions. This ratio is a good indicator of the boat's ability to handle rough seas.
  • The Displacement/Length Ratio (D/L) of the Beneteau First 375 is 204, which is considered moderate. This means the boat is neither too heavy nor too light, providing a good balance between speed and comfort.
  • The Comfort Ratio (CR) of the Beneteau First 375 is 25.5, indicating that the boat is designed for offshore cruising. This ratio suggests that the boat will provide a comfortable ride in most sea conditions.

  • The Capsize Screening Formula (CSF) for the Beneteau First 375 is 2.02, which is within the acceptable range for offshore sailing. This means the boat has a low risk of capsizing in heavy seas.

But what are the design ratios, and how are they derived?
