Of course the wind is never constant; in addition to this output board in planning mode affects the shape board, your weight, and your level of skill. However focusing on means you can quite easily find out what you need to sail for the most comfortable ride. It's the place where your sail will be large enough to maintain a gliding boar. If the wind is weak and vice versa it may be small enough not to lose control of the rush. For example, if your weight is above average, and the average wind speed 9.6, it is probably right for you to sail. 6.6-6.4 sq m defines strongly averaged wind power and is best suited for people who only started planning. The term "Power of Wind" means power of the wind measured at a sufficiently long period of time (10-20 min).
If the wind suddenly turned sour, and you are far from the shore, shovel will be much easier if you tie yourself to the board for a trapezoid, and you yourself will be floating in front of the board. If the size of the board allows the boom can be tied to the back loops, so that the tip was on the board do not move in slow motion, of course if you have one in spare.
If you break off the fin to reach the shore, you can tie a trapezoid of the rear board. It will help you more or less to keep course. If you break down half the boom, you can turn it over so to hold on to the integer part of the boom on a favorable tack to shore. In case of damage to carry any sail with him on a gurney roll of duct tape, preferably not the usual transparent and gray, it's a little thicker, but it sticks very firmly. Apply on both sides of the tape and you can go on, but at the first capabilities necessary to carry sail for repairs.
