3. Maximum Steady Heel Angle for Sailing Vessels

  3.1 The Maximum Steady Heel Angle to prevent downflooding in gusts is normally calculated for the Loaded Departure Condition, and may be increased if calculated for a lesser loading condition, such as the Minimum Operating Condition used for many ISO 12217 stability calculations.

  3.2 Where the stability of a sailing vessel is assessed using ISO 12217 in the Minimum Operating Condition, the Maximum Steady Heel Angle calculated using this lesser loading condition must therefore be reduced by 10% to allow for this effect, before insertion in the Stability Information and Stability Guidance Booklets.
