GENNAKER VS CODE ZERO CODE

This is a great option for sails up to 50 sqm, beyond which weight becomes prohibitive. For the MR and BR versions, a more economic but heavier solution is to use a heavy spinnaker cloth, such as Challenge NFS 94 (2.2 Oz) and NFS 144 (3.4 Oz).There are also race oriented versions of the CZ cloth, with more exotic fibers, and no protective taffetas. One side is reinforced by a rugged white or grey taffetas. We use primarily the CZ range from Dimension-Polyant, a film with reinforcing fibers in Polyester or Aramid.

GENNAKER VS CODE ZERO CODE

The go-to solution is a Code Zero specific film with reinforcing fibers (polyester, aramid, etc.

Cloth choiceįor all these sails, there are 3 main choices: However outside of the optimal target range, the sail will not have the best possible performance (just like a 150% genoa can be carried effectively to 150 degrees or beyond– but will not pull as hard an A2 Asymmetric) Cloth choice, furling, storage, etc. * These apparent wind angles are optimum and provide maximum sail performance – the sails can of course be carried below those wind angles, and will keep powering the boat strongly. It can get close to an A3 or A5 spinnaker and a top down furler (Seldén GX) is best. This sail is even wider with a mid girth of 80% +or- 5%, and draftier. The iSpinnakers Code Zero BR – AWA (Apparent Wind Angle) range 80 – 130 (à 150*. The CX mode will be used with the code Zero while the GX mode will be used with the A2 asymmetrical spinnaker. If you also have (or plan to get) a complementary A2 asymmetric / gennaker, ask us about the Seldén conversion CX/GX kit that lets you invest in a single furler unit that can be used with both sails. You can use either a top down (Seldén GX) or a bottom up furler (Seldén CX). Mid height girth of 70% +or- 5%, medium draft for reaching power. Perfect for a boat that has an overlapping genoa that will be used for tighter reaching angles. Our most popular concept, to complement your symmetrical spinnaker, or A2 style asymmetrical spinnaker. The iSpinnakers Code Zero MR – AWA (Apparent Wind Angle) range 60 – 120 ( à 140 *. It does require a lot of tension in the luff, and 2:1 purchase is recommended either at the halyard or at the tack line.

This sail has a nearly straight luff and is generally designed with a built-in antitorque rope, and to be used with our Seldén CX furlers. Racers may be constrained by their rating system to minimum girth of 75%. This primarily upwind sail is flatter and narrower than its sisters below, with a mid height girth of about 60%, +or- 5% for cruisers. Code Zero TR by iSpinnakersĪWA (Apparent Wind Angle) range 40 – 100 *. To simplify choosing the right sail we have developed 3 concepts that cover the entire range, with further customization of each concept available for your boat and program. In our range, look for the code Zero BR concept.Īs seen above, there is an infinite number s of variations in code zero sails to cover a very wide range of AWA, playing on girth and draft, cloth style and furling system. A top down furler may be used for this sail. This is an even wider and deeper sail, at times getting closer to spinnakers. With great boat speed, this code zero that can get as low as 130 degrees Apparent Wind Angle will be carried into true wind angles where slower boats would need to sail their asymmetric. you might have a very fast boat (catamaran or trimaran).The boat may have a symmetrical for running and is looking for a broad reaching sail, to bridge the gap with the genoa –.When looking for a broad reaching sail Code 0 target apparent wind angles AWA 80-130 In our range look for the Code Zero MR concept.ģ.

This sail that will take over reaching duty from broad to tight reaching and bridge the gap between genoa/jib and full downwind sails.

your genoa is not very big, leaving you with a power gap in broad to tight reaching angles.

you have a spinnaker or deep gennaker for deep downwind / running,.

This is the workhorse code zero for most situations: When looking for a true reacher (often called screecher) Code Zero – Code 0 target apparent wind angles AWA 60-120 Look at our Code 0 TR concept for this kind of sail in our range. Racers that must count this sail as a spinnaker will be constrained to a minimum width (75 % of foot), while sails designed for cruisers do not have that constraint and will be narrower.

A flat, fairly narrow, furler-mounted Code Zero / code 0 can take you from almost closed haul to a hair below beam reach, where the downwind sail(s) will take over. On a boat with a non overlapping headsail, there is a significant power loss as soon as you bear away from closed haul. Boats with non overlapping / self tacking jib – Code 0 target apparent wind angles AWA 40-100 Downwind sails and AWA Who can benefit from a Code Zero / Code Hybrid / Hybrid sail?Īpart from high end, money-is-no-object race programs, there are 3 broad situations where a Code Zero sail is highly beneficial: 1.
