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 Sj 320. That conversation is where a good sail becomes the right one.

Questions about the Sj 320? Email sales@krakensails.com and you’ll hear back from one of us, not a call centre. Read our story

Adventure and offshore

Sails for the long way round.

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 Sj 320 wardrobe changes when you leave the coast.

Questions about Sj 320 sails

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.
