![]() she may let the wind do the work more and not do the same kind of pumping and stuff that you do to get going. Example: What is the area of kite with diagonal-x 22 units and diagonal-y 5 units. Your gf's technique may be adapted to sailing overpowered if she is used to always being on sails a bit big for her weight. Maybe you could try using a handheld wind meter in conjunction with the calculator, and rigging your gf for the lulls?Ĥ. So a small person may need to rig a bit bigger than recommended to keep power and momentum in the lulls. A bigger sail integrates the gusts and lulls from a larger section of wind, and a bigger rider has more inertia to coast through lulls once up to speed. Small sails that your gf uses are shaped for heavier riders in higher winds, maybe with not enough belly for light air planing.ģ. are a greater portion of the total weight when the rider is light, so it becomes a problem that the calculator doesn't consider gear weight.Ģ. Is that your observation or hers? There's a couple reasons I can think of why that could be the case.ġ. That's interesting that the calc isn't working well for your gf. We can calculate perimeter of a kite when we know the length of each side of. So take the wind speed versus kite size recommendations with a grain of salt, and be careful. The perimeter of a kite can be explained as the overall distance around the kite. BUT the particular relationship between kite size and wind speed depends on the style of the kite, the quality and direction of the wind, the type of board, length of lines, etc. I also included approximate wind speeds in the right hand columns that you can match to your weight and kite size. Practice Question: Calculate area of kite for the following problems: N.B.: After working out the answer of each of the next questions, click adjacent button of see the correct answer. E.g., if 110 lb Tina is perfectly powered on her 8 msq kite, then 230 lb Lars should use his 16 msq kite. ![]() Pentagon is a two-dimensional polygon with 5 sides. I made this table so people of different weights can translate those recommendations for themselves, or figure out proportional kite sizes relative to what their lighter or heavier friends are using. We get the area of a kite by multiplying its two diagonals and dividing that number by 2. Most kite manufacturers make wind range recommendations for their kites based on a "typical" kiter who weighs about 170 lbs (77 kg). **Note #2: My famous WINDSURFING CALCULATOR is available at this link.** To see why this is so, imagine drawing a rectangle around the kite. If we represent the two measurements by W and H respectively, then the area of the kite is (1/2)WH. ![]() I have an updated version of the calculator, which incorporates wind ranges and board sizes and a graphical chart, at this link.** The width of a kite is the shorter distance between opposite points and the height is the greater distance between the other pair of opposite points.
