Anchor is Essential

Any yachtsman knows how important an anchor is. 
 
It is a calm night or daytime anchorage. And our last hope ("handbrake"), if an unguided boat is drifting to leeward shore, and the only thing you can do is to throw the anchor, hoping it will reach the bottom before the drifting boat reaches the reefs. 
 
So it's important to know how to handle the anchor, the winch, and the chain competently. And that's one of the basic skills we teach our cadets. Of course, we hope no surprises happen to their boats. But they'll be prepared for those...
