The concept can have a huge market in summer/family windsurfers if manufacturers also develop good
performance rigs that fit inside of the trunk of the car that
- with good enough planing experience and top end stability
- in sizes (7.5m2?) that allow, say, Bft 4 planing
Of course, never matching rigid board/monofilm sails kit. But
IF close enough
AND can fit in you car/in the apartment, this can be a huge comeback for windsurfing (and kiteboard decline?)
Currently there are rigs that fit inside the trunk of the car:
but not planning oriented (and I imagine very handful in higher winds) so very limited range.
On the other side, the technology to make compact and peformance rigs is already available. There are good/light performance sails made in Dacron:
