Storm and Heavy Weather Sails Interpretation

Published Fri 22 Nov 2024

An interpretation to Special Regulation 4.24 has been issued addressing requirements and the purpose of storm and heavy weather sails. 

The use of staysails has increased and the use of storm and heavy weather sails as staysails has become common practice, so as to reduce the number of sails required to be carried on board. Without better understanding of the purpose of storm sails, there is concern that the design and build of these sails is focused more on their performance as a staysail, than the requirements of a storm or heavy weather sail. 

The interpretation establishes a clear purpose for storm and heavy weather sails clarifies their primary role as safety equipment. The interpretation is also aligned with Word Sailing’s position. 

In short: 

  • Storm sails shall be designed to provide propulsion and steerage in 34-40 knots (Beaufort scale 8) and on all points of sail. 

  • Heavy weather sails shall be designed to provide propulsion and steerage in 22-27 knots (Beaufort scale 6) and on all points of sail.
