Sailworks are looking at several changes to the popular Flyer foiling sail range for the 2020 season. The existing Flyer range of 3.9m to 8.2m will likely not change geometrically, but they will introduce some lighter weight laminates for all sails in 2020, as well has some batten adjustments to tweak the draft profiles slightly more forward.
Two new sizes 8.5 and 9.5 will be added to the lineup for performance/competition foiling, they will be 6 batten/3 cam layouts like the yellow prototype seen here in testing:
We'll be stocking in the Flyer range for this season and look forward to seeing the new performance range by Christmas.

RDM Constant Curve. Ideal mast is NoLimitz Sumo.

But they work on Ezzy mast too. There is slightly different look on Ezzy, but still good enough, if you don't have the Sumo.

I can't speak for 2020 yet, but...

...all Flyers up to the 7.0 rig on rdm masts. The 7.0 and 6.0 both take 430. I foil the 7.0.

The 8.2 requires a sdm 460 mast.

We will see what the 2020 models require. Yes, Bruce P goes out and test rides 2020 prototypes. He makes it look easy. Of course, he could make foiling a bed sheet look easy.
