International Moth Bi-9DSXR 3Di Mainsail

Decksweeper | Mast Length: 5000mm

The Bi-9DSXR Decksweeper 3Di Mainsail is a reduced sail area version of the Bi-9DSX for the Beiker designed International Moth.

This sail can be used by any sailor when it gets windy for reduced upwind drag or by lighter sailors as an all-purpose sail across the wind range.

This sail is recommended for mast length 5000mm and standard 260mm mast stump. Maximum luff length and careful distribution of shape and luff curve have produced a fantastic, easy-to-use Decksweeping sail for both upwind and downwind sailing.

The sail is built using North Sails 3Di technology and is a further development of the successful Bi-8DS design with an extra-large Decksweeping section to further optimize aerodynamic efficiency.
