CarbonIndex has been involved in the manufacturing process of the International Sonar for the past 5 years and is now the official UK and European builder and distributer for the class. All the boats we have produced have proven track records, we concentrate on strength and lightness in the build and pride ourselves in our knowledge and understanding of what is required by Sonar enthusiasts and just what the boat is actually capable of. We can offer advice on sails, fittings and tuning the yacht whilst strictly adhering to the one-class rules.
