1/3/2024 0 Comments Code zero furler priceWhat happens is, say you are going nearly upwind in 5 or 6 knots, you may be doing just 4 knots with your jib, and because you are not going that fast your wind angle is a bit wide. A Code zero can also be used in more wind when the wind angle is a bit wider and can take the place of a reaching Asymmetric.Ī code zero, in many conditions, can virtually go as High as a boat with just a jib. A code zero in 5 or 6 knots at a 50 to 70 degree wind angle is an absolute weapon, and if you find yourself in these conditions, and don’t have one of these, expect to see boats come over the horizon behind you and sail right past you, perhaps doing as much as 2 knots or more extra speed. Now technology in sailcloth and with better design, they can be made to virtually look like a Jib, but still, they are rated as a spinnaker.Īs I mentioned above, it is generally used in lighter reaching conditions, when it is too tight an angle to hoist even an Asymmetric spinnaker. In years gone by they were flappy leeched sails, that were not that efficient. So all the sail designers have engineered the Code zeros to comply with this rule, and recently they have become much more efficient than they used to be. If you don’t have this, it is counted and rated as a Jib, which would be punitive for your rating. IRC imposes a restriction on these code Zero sails which means to count them as a Spinnaker the mid girth must be at least 75% the size of the foot. However, these Code zeros are not restricted by IRC rules. You will likely have seen code zeros on fast offshore yachts such as the Volvo 65 ’s, IMOCA 60’s and others. "You can put up three times more sail when you hoist a code zero, compared to reaching with your non-overlapping jib" The big difference is you can normally put up 3 times more sail when you hoist a Code zero, compared to reaching with your non-overlapping Jib. The loss in power when you’re reaching with a non-overlapping headsail became a problem, so to address this issue, Code Zeros were developed. Barry Hayes of UK Sailmakers Ireland reports.īoat designers then all started designing their boats with these smaller headsails which were excellent upwind, but it became evident that reaching in lighter airs was an Achilles heel for them. Also, the IRC rating rule seemed to be more advantageous if you reduced your headsail size to the same as the foretriangle. Then it became evident that this set up was not that efficient and trying to manage very big Geneos was difficult and needed a lot of grunt to tack them. Up to about 15 years ago, most boats were designed with big overlapping headsails, which were still pretty useful when reaching because of their size.
