    In our previous blog we spoke with Ronan Grealish from North Sails on the topic of reaching sail configurations for doublehanded racing. In this blog we continue the conversation to take a closer look at the design philosophy and evolution of the code zero. Modern top-down furling code zeros such as those from North have come a long way since the traditional flappy leech sails of late.

    Reaching legs are an inevitable feature of coastal racing, and a good setup can produce some of the fastest and most stable sailing. We are talking about that range of off-wind angles, where an eased jib is no longer effective, but the TWA is still too tight for a spinnaker. This is where speciality reaching sails are needed. Exactly what these angles are depends on the boat and the wind strength, but for context lets assume a range of 060-120 TWA.

    It is up to us, sailors, navigators, racers, and adventurers, to act for the preservation of the oceans, our wonderful playground. Innovations are flourishing, attitudes and habits are changing, and builders and designers are now giving priority to the eco-design of boats and fittings, and to the search for more ecological materials. In this blog we shine a spotlight on the innovative construction technology in the Eco Concept furler range, and say congratulations to Karver Systems for doing their bit for the environment.

    If you have a 25-30ft sailboat and you are looking to boost your sailing performance with a code zero or asymmetric spinnaker then you will need a furler in the 900-1000kg working load range. There is a decent selection of different products available at this size, but which one should you chose? In this blog we run through the relative pro’s and con’s of the main contenders.

    We are constantly reporting on the latest innovations in the marine industry which offer weight savings whilst, at the same time, increasing safety factors. The result: lighter, faster, safer and more exciting sailing.
