Perfection of Details

Sail is studied to achieve maximum performance in all the sailing conditions according to the suggested weight of the sailor. Every smallest detail is designed and elaborated to achieve the premium quality sail, even if it increases the production time and costs.  Still today every sail is assembled and then controlled personally by Claudio Demartis assuring that all sails are perfect and uniform.  We are a unique sailmaker putting this level of attention to each sail in the sail-making process. 


The highest quality fabrics - the 2.99 polykote Dacron from Contender guarantees the best technical characteristics and the most durable sailcloth in the Optimist class.

Winning Features

The geometry of the sail is developed to ensure maximum performance in all wind conditions.

The shape and surface of the sail in combination with the position of the battens ensure that the sail is easy to trim, especially at the top part of the sail. Length and stiffness of battens are adapted to match perfectly the designed shape of the sail.

The cross-cut (horizontal) positioning of the panels has won the most races in the past 20 years. This paneling approach was started by Claudio Demartis in Olimpic Sails already in 1986. Since then it has become one of the best-performing solutions used for the most successful sails all over the world.


Our sail design responds to the International Optimist Dinghy Association (IODA) class rules. Every sail is constantly measured and controlled during the production process and certified according to the Optimist Class regulations.
