About the Nacra 15 and Nacra 17 Catamarans
Nacra 15 – Pathway for youth sailing
Designed from scratch to the ISAF criteria to become the new official ISAF youth catamaran. The older catamarans in this program need replacement as the youth of the world wants to sail in a catamaran that can carry more crew weight and is a modern design than the current ones. The Nacra 15 went into production in 2015.
The Nacra 15 resembles a lot to its bigger sister, the Olympic Nacra 17. In fact, the Nacra 15 is a mini version of the Olympic Nacra 17, creating a pathway towards the Olympics.
The Nacra 15 carries also two curved dagger boards that like in the Nacra 17 provide lift. This provides an extra dimension in sailing, as the Nacra 15 is a semi-foiling catamaran. More lift means; drag reduced means; more speed and excitement.
The rudders are fitted out with stabilizers, which control pitch of the platform so all power can be transferred into speed.
The Nacra 15 as an “stepping stone” for youth and the Nacra 17 in the Olympics.

In May 2012 the International Sailing Federation (ISAF) selected the Nacra 17 as the equipment for the mixed multihull event at Rio 2016 . Morrelli & Melvin designed the Nacra 17 from fully in line with the specifications given by ISAF for the Olympic multihull 2016 and it is produced by Nacra Sailing International, a Dutch company based in Scheveningen (The Hague).
The all-new design is about 17 feet long with:
Wave piercing design – Wave piercing designs have a minimum draft resulting in a boat which has less drag and tends less to rock, creating a more constant high speed than conventional designs
Stiff platform – The Nacra 17 is one of the stiffest production platforms available in its class, resulting in direct response in the boat and the energy of wind is maximum being transferred into forward motion
Light boat – The Nacra 17 being light for its length ensures superb handling on and off the wate, broader wind range during regatta’s, Resulting in a agile and therefore challenging boat to sail
Rig – Powerfull carbon mast to ensure both safety (re-righting moment versus crew weight) and performance, modern High aspect ratio cut sails, easy power up/power down, engineered by one of the most experienced multihull sail makers in the world
Curved foils – The Nacra 17 features curved boards lift the lee bow out of the water and reduce drag significantly at the same time as creating pressure and therefore sooner hull flying and trapping. Additionally sheet loads are reduced making crew weight less critical
The Nacra 17 design features result in an agile high speed machine giving both sailors and spectators a spectacular close racing fleet. In February 2013, the Nacra 17 was selected HISWA Boat of the Year.
