Summarize this article in one sentence.
You will want a beginner or training kite with high stability, a wide wind range, and moderate turning speed. Beginner kites are usually smaller and advertised as such. Maximum upwind drive is also important. As you get more experienced you can feel free to pick a kite board that suits your individual style and needs. Be sure to pick a kite that is appropriate for your bodyweight. They should be clearly labeled. Normally a beginner will practice with a soft trainer kite first; this has a size of 0.5 to 1.5 meters squared. Then you'll buy a bigger kite depending on the local wind conditions. This kite will be in the size range of around 7 to 13 meters squared. You use bigger kites for lighter wind and smaller kites for stronger winds. If you are unsure, ask a dive or surf shop employee. Choosing the right kite surfing board is essential. Every kite surfer is different, and you'll need to find one that is comfortable for you. Beginners will usually want larger, more stable boards. Be sure to pick up a board that is advertised for your weight. Your board shouldn't be too heavy. You should be able to carry it in one hand. Make sure it has secure bindings to keep your feet connected to the board. As you become more skilled you may want to get a smaller board, with more rocker so that you can learn to do tricks. In addition to having secure bindings on your board you will need safety equipment. You'll want an impact vest and a helmet at the very least, especially if you are a beginner. Be sure to also equip yourself with a safety leash to be able to use your kites safety release function. You may also want to wear a wetsuit, especially in cold water. A secure bathing suit is necessary. A string bikini probably won't do.
Pick the right surf kite. Select a kite surfing board. Get together your safety equipment.
