With GPS enabled, the software recognizes where you are. All you have to do is click on “Drop Anchor” and it notes where your car is parked.
打開GPS，軟件識別出你的所在，你所要做的就是點一下 “Drop Anchor”（下錨），它就會在你停車的地方標上個記號。
For example, a scope of 7 to 1 means that with a water depth of 17 feet and the boat’s bow 3 feet above the water (total vertical drop of 20 feet), 140 feet of anchor rode would be let out.
例如，a scope of 7意味著儅水深爲17英尺，船頭距水麪爲3英尺時（縂共的垂直落差爲20英尺），140英尺的錨纜將被放出。

So why not be able to pick up and drop anchor for the sake of cohesion?
