For 10 years Avanti has led the way in windsurf membrane sail development. Our flagship racing sail, the Machine, has claimed victories and World Cup podiums against the very best. For 2021, we will relaunch the Machine M-8, first introduced in 2020. Sail features remain unchanged, only minor changes to adjust cam pressure have been implemented, whilst the sail features a brand new graphic design that free up the sail top for better placement of sail numbers and board sponsor stickers.
The Machine M8 features a higher aspect ratio and narrower head outline, particularly on the larger sizes. Also found on the M8 is our exclusive clew plate system combined with the Quick Loc pulley.
Progressive Sock Widths
New for the Machine M8, luff sock widths in the upper 1/3 are systematically widened, as a function of overall chord length, for essential drag reduction.
We started with our own exclusive, ultra-light membrane construction. Proven, copied and ranked, our membrane is engineered to distribute loads evenly and appropriately throughout the sail skin in a way that traditional paneled sails cannot replicate. We call this Smart Load Technology; fiber and strength where you need it, weight savings where you don’t.
Building on the success of the M-7, we once again set the M-8 up on a 7-batten structure. The cross-batten is aligned to exit at th eclew for superior stability when sailing deep in negative outhaul modes. From the cross batten up, battens are flowed quickly and aggressively to stay airflow aligned.
