International Moth Vi-9DSX 3Di Mainsail
Decksweeper | Mast Length 5100mm
The Vi-9DSX Decksweeper 3Di Mainsail is an all-purpose, maximum sail area sail for the majority of International Moth designs including the Exocet, Mach 2, Rocket and others.
This sail is recommended for mast length 5100mm and standard 60mm mast stump. Maximum luff length and careful distribution of shape and luff curve have produced a fantastic, easy-to-use Deck sweeping sail for both upwind and downwind sailing.
The sail is built using North Sails 3Di technology and is a further development of the successful Vi-8DS design with an extra-large Decksweeping section to further optimize aerodynamic efficiency.
