In Topic: Handle length

19 April 2013 - 04:53 AM

It is actually the difference between the top end and the bottom end which controls the relative lengths of the lines. Thus holding a bit lower just means the bottom moves a little less while the top moves enough in the opposite direction to make up for the amount the bottom doesn't move. Do the math and you will see that the difference (total motion) will be the same for a given angle no matter where you hold the handles. This is for a given handle length; as CodyG's image demonstrates, longer handles equate to more motion-per-angle-change.

The one change when adjusting where you hold the handles (and it is very small) is that with a top-hold you are having all the motion occur at the bottom end and means that you are slightly loading the bottom of the sail as you change angle in the braking direction, whereas if you hold the handles near the middle, you will be doing less loading of the bottom of the sail and slightly unloading the top of the sail. This is such a small amount (inches) compared to moving your arms (many inches) or taking a step forward or backward (a foot or more) that it can be ignored. If you want to load or unload the sail you won't be doing that by rotating the handles.

 

Changing where you hold the handles just changes which muscles you are using to hold (in a steady position) or to rotate the handles. Holding the handles so there is no tendency for the line tension while in a hover to rotate the handles (you just pull the handles toward you). Holding higher (thumb on the top end) means you have to exert effort to pull the bottom more than the top (while in a hover). The muscles that control your ring and pinky fingers, and the muscles that rotate your whole hand toward the pinky will be under constant tension. Some like this, because it means you don't have to make the transition from no muscle tension to muscle tension. I suspect that it makes your reaction time a tiny bit quicker, and may also provide better feedback about what the kite is doing. I also suspect that the muscles that rotate your hand down are a bit stronger than the ones that rotate it upwards. I know that a mid-hold will soon result in sore muscles along the top of my forearms. The most comfortable hand position (for me) is with the thumb being a nearly straight extension of the forearm and the fingers angled slightly down.


In Topic: Never used music. Am l missing out?

11 March 2013 - 06:57 AM

I never fly to music. For me music of any kind is one of two things: the absolute focus of my attention to the exclusion of EVERYTHING else, or really annoying noise. I like music, but not while I'm doing something else. Exceptions are dancing (of course, although I have been known to totally ignore my partner) and while driving (music and driving seem to occupy different parts of my brain).


In Topic: Brand New Midvent Pros!

I have to note that those seem an odd color choice for someone from Columbus, OH.

I thought that Maize and Blue were forbidden colors down there. Posted Image

In Topic: Obliviots

OMI (Obliviot Motorized Infantry)
[...]
Note the tire tracks going over my flip flops, two kite stakes, and 8 lines. 5 feet from my sitting position lawn chair next to pick-up.


You need a chunk of pipe, as heavy as you are willing to carry, which you can drive in next to your handle stake. Put a banner on it if you want something decorative. Two five-foot pieces of 1/2" with a coupling should be enough, and fit in the bed of the pickup easily.

BTW, Obliviots are not found only on the sand-side of the waterline: I once had another boater try to go between my boat and the boat I was towing.
