when a blade trigger has a range from
buy something different...
my gaastra pure 2016 in 13 QM goes from 12 to 24 at 80 kg..... i thing the 14 to 18 knots cannot be true its a really small range for one kite - nobody has such stable winds - i would be always changing my kites
A bit of misunderstanding here: Blade trigger standard range is not 14-18.
Kev used weight calculator from Blade site to find "optimium" size for 94 kg rider.
So site recommends using 12 above 18 knots for my (!) weight.
The range of 14 m Blade Trigger for standard 75 kg rider rider is
11-18 knots (beginner); 10-21 (intermediate+) -
which is similar to what you say you get from yours (although top values is given as lower).
I think it is probably a bit on lower side though (in real life it is probably more like 12-20).
for 10m 75 kg it range is given as
15-28 (beginner) 13-30 (intermediate+) knots.
So if I am to take beginner range numbers from Blade the envelops do overlap to the tune of 3 knots.
But obviously standard 75 kg rider will have "non-optimum" size for somewhere around 16.5 knots where:
14 m will be a bit too much (11-18)
10 will be a bit small ( 15-28).
Now: I am 20 kg more which is weight ratio of 95/75=1.26. Square root of this is SQRT(1. = 26) = 1.12
which is the wind speed factor for me.
So for me awkward wind speed will be 16.5*1.12 = 18.6 knots.
This seems a bit worrying as 18.6 knots = 21.3 mph which is usually considered "close to perfect" for a beginner kitesurfer.
More stupid questions
Question 1) Could someone with "wide" quiver like 10 + 14 m (95kg) or say 9-12 m for 80-85kg - how bad this middle point actually is?
I kind of suspect it is not actually too bad?
Question 2) It is typically (often) gusty here in Scotland.
if I take an example: 17 mph average with gusts to 28 mph forecast.
Do I as a beginner:
A)have to have my kite range match 17-28 wind gust range (or be wider)
B)CAN have a lower range kite say 15-24 and basically stop riding (kite downwind, lots of depower,bar fully out, may be slow down and sink) when a gust comes in? Gusts are usually short in Scotland...
C)MUST use a kite with a higher range say 10m is 15-28 knots (17-31 mph), i.e. average wind 17 mph will be hardly enough to kite,
but I will be probably much safer when a gust comes in?
Or to re-phrase Question 2:
is it a huge problem when I am riding a kite with top of the recommended range say 10% lower then possible (short) gust speed? Is it too dangerous?
must my kite range include the top gust speed?
