Sizing Tool
Storm Jib Calculator
Enter your boat’s foretriangle height (the I measurement from your class certificate or sail plan) and we’ll calculate the maximum OSR-compliant storm jib dimensions and suggest the right size from our range.
Where to find your I measurement:
Your boat's I dimension is the vertical height of the foretriangle — measured from the deck at the base of the forestay to the forestay attachment point on the mast. It's on your class measurement certificate, your sail plan, or your one-design class rules.
Construction Detail
Designed for When It Matters
A storm jib isn’t a small jib. It’s a purpose-built tool for survival conditions. Every design decision comes from ocean racing — where the same sail may need to be set by an exhausted crew at 3am in 45 knots.
Our storm jibs are designed to World Sailing Offshore Special Regulations for Monohull and Multihill (Category 0, 1, 2) the most demanding offshore racing category. This means the sail provides propulsion and steerage in Beaufort Force 8 and above, on all points of sail. The right piece of safety equipment for any offshore passage, racing or cruising.
High-Vis Dayglo Fabric
We use certified dayglo orange laminate — the same family of colour specified by OSR for post-2013 storm sails. Visible to crew, coastguard, and SAR aircraft. The colour isn’t decorative: it’s a survival feature.

Independent Hank-On Luff
Hanks are sewn and stitched directly to the luff tape — permanently attached and fully independent of any luff groove or furling foil. Per OSR Rule (d), your storm jib must attach to the stay without relying on the furler.

HMPE Reinforcement
Dyneema (HMPE) is used throughout the luff rope, clew patches, tack patch, and corner load-path reinforcement. Aromatic polyamides (Kevlar) are prohibited by OSR and not used. HMPE gives exceptional strength-to-weight with excellent UV and fatigue resistance.

Wrap-Luff for Easy Hoisting
Soft wrap-luff anti-twist elements allow the storm jib to be hoisted over a fully furled headsail without snagging, critical when deploying in deteriorating conditions and the headsail is staying on the furler.
