Calculate anchor line lenght

-Google Play is coming to the new application which calculates the necesary anchor line length.

-The permissions requested by the application are not used in the application at any time, we are studying how to remove them.

-The calculation made ​​by the application to know how much chain you have to drop, is based in the weight of the chain and not in the anchor, the key to a safe anchorage is based. The force exerted by the chain in the direction parallel to the surface of the water can be determined by the formula of the catenary. The wind exerts a force, also parallel to the surface of the water on the boat depending on the length. Ideally the two are offset. You can arrive at an approximate formula for the necessary chain for which the two forces are matched and the last link of the chain (the more close to the anchor) have a zero force, ie,the anchor is quietly resting on the bottom.

Actually the anchor is just a reference point, but only to the specified wind or sea currents without for greater wind anchor must, of course, be fully engaged because that's when he starts working. It is a length value for which you dont need to worry if the anchor is right or wrong hooked. This indicates also, in general, is that the longer the chain density (kg / m) much better and less we will have to occupy the anchor.

-Soon will make more updates in order to improve certain aspects of the application also incorporate your suggestions.
