< 35 kg
Optimist Mainsail


VAT Excluded
Easy & speedy - by being fast and easy to trim, it's preferred optisail of many lightweight sailors under 35 kg.

The sail number(s) will be printed on the sail using a dark gray color.

Sailcloth and Design

The  CD Flat sail is made with 2.8 polykote Dacron from Contender.  While the technical characteristics and durability of this sailcloth are the same as for 2.99  polykote Dacron, this material is 15 % less elastic in the diagonal direction.  These material characteristics assure that even in conditions with strong wind, the sail will be able to maintain better its initial shape.

For Lightweight sailors, it means that it will be easier to manage the sail and keep the boat stable when the wind is increasing.  

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.


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 and an official sail measurement certificate is provided for each sail.

Innanzitutto grazie Claudio per questa Super Super Super Vela! Vela molto performante per il mio peso (30kg) e per il mio stile di conduzione in ogni condizione di vento! Una vela con cui riesco ad orzare molto di più senza sacrificare il passo e che dal primo giorno mi ha dato grandissime soddisfazioni! Grazie ancora di tutto prestissimo, Ricky ITA 9172
