For racers who want every bit of extra performance, Doyle Sails has developed a range of highly specialized downwind code sails that reflect Doyle's commitment to delivering the very best product to their customers. These unique designs are meant to complement individual boats' other spinnakers and provide needed power in specific situations. These sails are highly customized to each individual boat and highlight Doyle’s diverse and innovative engineering capabilities and advanced construction techniques.


The Code 0 is a highly specialised sail used to sail higher reaching angles and flies with a straight luff, allowing for easy sail trim for optimum reaching perfromance. The tight luff also allows the sail to be easily depowered by simply easing the sheet or tweeker, as the design allows it to twist off more like a conventional headsail, without collapsing like a spinnaker. Covering a wide wind range, combined with a furling system, these sails are a popular choice for the sailor who is looking for an easily handled sail to improve their downwind and reaching performance. The sail is designed in high strength materials and fibres to ensure that the sail is durable.

Recommended True Wind Angle: 60 – 120 degrees

Recommended True Wind Speed: 4 – 15 knots


The Cableless Code 0 is a revolutionary sailmaking application that eliminates the use of torsion cables – giving more luff projection for deeper angles, more range and less weight.

An uninterrupted lens of unidirectional fibres designed in the luff of the sail takes the load from the tack all the way to the head. The secret behind the concept is that the load is taken along the sails natural load path instead of requiring many tons of cable tension to try and keep the luff tight. In the Cable-less Code 0 the luff is pushed to windward creating a far straighter luff for a fraction of the load and allows the luff to be eased and flown for deeper angles. When it comes time to furl the sail away the bands of unidirectional Carbon running down the luff allows for a quick and easy ‘bottom-up’ furl.

Recommended True Wind Angle: 60 – 120 degrees

Recommended True Wind Speed: 4 – 15 knots


Similar to a Code 0 a Fractional 0 is used for reaching and running but flown on a fractional halyard instead of a masthead. Used in high-performance racing in heavier conditions.

Recommended True Wind Angle: 90 – 130 degrees

Recommended True Wind Speed: 12 – 30 knots
