Christine,
As a few people wrote already, - you may benefit from a monopod for
the steadiness, especially if you are going for anything longer than
200-250 mm on Pentax APS body.
As for what focal length you need, - it depends on what you want:
just a full-height figure, that with the kite, or just the face?
You can use e.g. the 1st calculator here to estimate the size of the
image, depending on the size of the object and the distance:

Example: for a 2000 mm (2m) object (~6'6") at a distance of 100 m (~100
yards) and choosing the last option for the image size of 12.8mm (APS-C
sensor is 14.8-mm-high, you get the desired focal length of 636 mm.
So, a vicinity of 500-600 mm would be just right for that. And that's
what Paul has suggested.

Best bet here would have been the 500 mm lens or the 300 and 1.4
converter. The 60/250 plus 1.4 converter would be an okay substitute with
cropping. Tripod or monopod would be helpful but with ISO 1600 quite
acceptable you could get away with hand held, shooting wide open.

Hi Everyone:
We had exceptional winds today, so I thought I.d head to the lake to
catch some waves. The white caps were prominent to be sure, and there
was a bit of splashing waves a tad north of where we were. Higher
waves, which flooded bits of Lake Shore drive, could be found south of
us - closer to downtown. We were up north by Wilson ave.
Anywhooo, The spot we stopped at is the put-in spot for jet skis and
windsurfers and such, and we got lucky since a handful of windsurfers
were taking advantage of the high winds.and boy were the winds high.
It was really hard to take pictures. I couldn.t keep the camera or
myself steady. The wind was coming from the northeast, and if I tried
to shoot into the wind, sand carried along by the wind stung my face so
bad.for the first time, I was glad to be wearing glasses! By the end of
the shoot, I had sand everywhere, hair, mouth, ears, and even in my
camera bag. I had to do a big shake-out when I got home.
Darrel was with me, and he tried to act as wind-break for me, but it
didn't really help much. It was such an exhilarating shoot.lots of fun
to try to deal with the elements while trying to shoot. I.d like to do
more bad weather shooting.though I don't think I'd like to chase
tornados and such.
I really would have loved a longer lens. Most of the photos below are
deep crops. I did the best I could with the DA* 50-135.
So I have a question: Darrel thinks were were about 100 yards (a
football field) from the surfers. Given this distance, which would have
worked better, a 200mm or 300 mm prime to catch the surfer action?
