Limit marks and setting equipment

World Sailing · 2025–2028
In short

Limit marks are permanent, clearly visible contrasting marks identifying measurement points. When applicable, they control how high a mainsail is set, the boom’s position and how far a sail or bowsprit extends. An event limitation mark has a different purpose: it identifies equipment whose replacement is controlled during that competition.

The rule

Limit marks are permanent, clearly visible contrasting marks identifying measurement points. When applicable, they control how high a mainsail is set, the boom’s position and how far a sail or bowsprit extends. An event limitation mark has a different purpose: it identifies equipment whose replacement is controlled during that competition.

In practice

For a triangular mainsail, the upper-limit requirement relates to the projected line through the mast’s upper point; the boom and bowsprit have their own defined references. Do not assume that a decorative stripe or the outside edge of any tape is the legal point. Class rules can change the specified equipment-use provisions where the Equipment Rules permit them to do so.
