Whats your range on the 15m Elf Peter?
Must admit, I dont know....
And might never find out, as because I am not racing, I only use it for marginal conditions.
Meaning, as soon as the wind approaches 10 knots, I am out on a 9 or 10m2 LEI.
Havent had it for long, and only been out a couple of times, so no idea what "my" windrange is, sorry.
The low end is amazing, and compared to my 13m2 DYNO from 2011 (the powerful year), it is in another class, especially because you dont have to loop it to keep it flying (well, a lot later if the wind is dying)
I dont like giving wind speeds for light wind, as the last time I was out in the most marginal wind, I could only measure 4 max 5 knots (77kg).
BUT, I dont believe this myself for sure, as wind speeds can be soooo deceiving in light wind, because even small gradient differences will make most measurements obsolete.
My friend (a bit heavier but a really good low end board for getting on a plane) has ridden with the ELF 18m2, where the weather station at 8m height just next to, was showing 4 knots in average.
Again, it could just as well be something like 6 or maybe even 7 knots, because as said - low wind claims are often faulty and really difficult to compare IMO.
As said - the upper range I will most likely never know, only the racers will.
They ride with (okay, CHOOSE) the 15m2 (ELF or Chrono) in 12-13 knots too.
Necessary for max VMG up and downwind.
So sorry Dave, dont know the windrange yet, and as said - because I wont hardly use it in the upper end, I might not be able to tell you, as the low end is always some mumbo jumbo one can not really take for real, no matter how objective one is trying to be....
It might as well be 7 knots
