Tight Anchorage
There are degrees of tightness in anchoring. If you have room for the boat to swing around without hitting anything, then you can just use a two anchor V, where the angle between the two anchors is fairly large (between 140 and 180 degrees, closer to 180 for less movement, but requiring larger anchors). This keeps the bow in one place, but allows the stern to swing around, keeping the wind head on (this is usually more comfortable for sleeping.) However, if there isn't room to turn the boat around, either due to other boats, the shore or underwater objects, then you need to set a V anchor set at the front, and an additional anchor at the back. This keeps the boat stationary, but tends to be less comfortable. An alternative, if the wind is coming from the stern, is to put the V anchors at the stern and a single anchor at the front. Sometimes you can use trees on land as one of the anchors
