Medium depth sail with well-equilibrated curves - great all-around sail for sailors with a weight between   35-40 kg. 

Sail that assures all-around performance in all conditions and for all sailing levels. One of the most popular sails in our range as it assures great performance for both  - cadets and juniors!

Perfection of Details

Every aspect of the sail is studied to achieve maximum performance in all the sailing conditions according to the suggested weight of the sailor.  Each sail is assembled and controlled only by Claudio Demartis allowing to ensure  the same precision, quality and equality of all the CD sails.  


The highest quality fabrics - the 2.99 polykote Dacron from Contender, ensure 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. The length and stiffness of battens are adapted to match perfectly the designed shape of the sail.

The tabling is precisely elaborated and adapted for various edges of the sail to maximize the performance.


Extra Power

Our sail design is developed to reach the maximum possible dimensions according to the International Optimist Dinghy Association (IODA) class rules. Every sail is constantly measured and controlled during the production process.
