Often, when you think of kayaking, you don’t think about anchors. You want to move! But if you are using your kayak to fish, hunt, or take pictures, you want (need) to stay in one spot.
One of the most common mistakes involving anchors is using too little anchor line when trying to set the anchor. For boats, the golden rule of anchor lines is 7:1. That means for every 1 foot of water you are in, you will need 7 feet of anchor line. For example, if the water is 10 feet deep, you would need 70 feet of anchor line. For kayaks, 7:1 may be a little extreme, but it’s always better to have out too much line, rather than too little. The idea behind the golden rule of anchoring is that you do not want the anchor line to be straight up and down in the water. If it is, the anchor will not fall on its side and will not catch the bottom effectively. Too little anchor line will result in dragging. With a longer anchor line, the angle of the anchor line to the bottom will be much less, allowing the anchor to dig in to the bottom much more effectively.
Keep in mind that as the water level changes with tides and currents, you may need to adjust your anchor. When in doubt, always use more anchor line than you think you will use.
