A code zero is strictly a downwind sail. A code zero is often classified as a spinnaker in terms of racing, hence the restriction on the length of the mid-girth, but it’s not a true downwind sail. If you’re going downwind, you’ll use either a symmetrical or asymmetrical spinnaker.
How much faster does a Code 0 sail make sailboat go?
Cruising Code Zero for non-overlapping boats Apparent wind speed: 1-16 knots. Approximately 60% of the sail area of a full-size spinnaker and about twice the size of a non-overlapping genoa. Use with a “top down” roller/furler with a torsion rope sewn into the sail. Made with Code Zero laminate cloth.
What is the difference between a gennaker and a code 0?
A Code 0, for example, is a gennaker, but a Code 0 is a racing sail, while a gennaker is usually considered a cruising sail. Ultimately, there are four or five different types of asymmetrical spinnakers, with each sail designed for a specific wind angle range. As such it will also be similar to a reaching gennaker.
What is a code 3 sail?
Code 3 is a medium air reaching sail, used for apparent wind angles near 90 degrees. Code 4 is a heavy air running sail, used in the heaviest winds normally expected. Code 5 is a heavy air reaching sail, used in the heaviest winds normally expected. Code 6 is a storm sail, for running in storm conditions.
What is a gennaker sail?
A gennaker is a sail that was developed around 1990. Used when sailing downwind, it is a cross between a genoa and a spinnaker. It is not symmetric like a true spinnaker but is asymmetric like a genoa, but the gennaker is not attached to the forestay like a jib or genoa.
What is the purpose of a gennaker?
The gennaker is a specialty sail primarily used on racing boats to bridge the performance gap between a genoa and a spinnaker. It is sometimes the only downwind sail on board because it is easier to use and less expensive than a spinnaker. Due to its geometry, the sail is less prone to collapsing than a spinnaker.
What is a Ballooner sail?
Definition of balloon sail : a large light sail (such as a spinnaker) set in addition to or in place of an ordinary light sail especially by yachts in moderate weather.
What’s the difference between a genoa and a job?
Colloquially the term is sometimes used interchangeably with jib. A working jib is no larger than the 100% foretriangle. A genoa is larger, with the leech going past the mast and overlapping the mainsail. Working jibs are also defined by the same measure, typically 100% or less of the foretriangle.
What is a code zero sail?
The Code Zero got around the rule by measuring in as a very narrow-flat spinnaker with shape similar to a reaching geona. When not constrained by rating rules, cruising sailors have a lot more options on the size and shape of a “code” sail.
How much wind do I need for cruising code zero?
You can typically use a cruising code zero from 70° true wind angle (TWA) in very light air up to 110° TWA in 15+knts. Ultimately it depends on the righting moment of your boat and how comfortable you are with how much the sail may make your boat heel in significant breeze or at tighter angles.
How do you control a code zero on a boat?
There are three different methods for controlling a Code Zero. For boats 33 feet and smaller, sails are small enough that a furler is not necessary. For mid-sized boats 33-44 feet, a simple direct furler is the best option; for boats over 42 feet, you’ll need a top-down furler to handle the Code Zero, which is getting quite big.
What is the difference between the code zero and cruising spinnaker?
The Cruising Spinnaker is bigger and rounder and designed for broad reaching. Photos courtesy Berckemeyer Yacht Design. The Code Zero is a cross between a genoa and an asymmetrical spinnaker that is used for sailing close to the wind in light air.
