Who's making your sail
Real sailors.
A real loft in Geelong.
Every Kraken sail is designed from your boat’s own measurements by a designer who still races at international level, and built in cloth made in Europe or America. Before anything is cut, Christie or Ryan checks your numbers and talks to you about how you sail your Dufour 40. That conversation is where a good sail becomes the right one.

Passage making asks more of a sail: weeks on the boom, sun and chafe, and a third reef when it blows. Here is how the Dufour 40 wardrobe changes when you leave the coast.

Questions about Dufour 40 sails
How much is a new mainsail for a Dufour 40?
From A$5,401 (US$3,100 in the US) in Dimension-Polyant Optimum Cruise with a full head batten and three leech battens, or A$5,599 with four full battens. C-Breeze costs more. Racing mainsails start from A$8,635 in PX film.
What size genoa does a Dufour 40 need?
Dufour 40s racing under ORC carry a headsail of about 32.6 m², about 98% LP on this rig (median of 1 certificate). That makes it a non-overlapping jib boat, so a 110% furling headsail (about 35.3 m² on this boat) is the closest match to how it is designed to sail. A bigger overlapping genoa may not sheet well on this deck. A 110% genoa in Optimum Cruise is A$4,043 (US$2,325 in the US).
Can I race in cruising sails?
Yes, plenty of club racers do. If results matter, a laminate main and headsails hold their shape far longer: open the configurator to compare.
How long does it take?
Cruising sails take about 4 weeks to build, then ship express. Racing laminates take about 4 weeks and membranes about 6 once the design is signed off.
Do the prices include GST and shipping?
A$ prices include GST. US$ prices are before local taxes and duties. Shipping is added at checkout: A$75 in Australia, about US$75 plus duty prepaid to the US.
