Tips for Choosing the Best Anchor River

Choosing the right anchor for your boat and boating style may seem daunting because of many different options. But don’t be dismayed. Here are six tips that will help you make the right choice.

top 8 river anchors

1. Consider the Size Your Boat

The right anchor size you need depends on the size of your boat. By size, it generally means the overall length of the boat. In general, the longer (or bigger) your boat, the larger and heavier the anchor should be. To be safe, get the largest possible anchor for the size of your boat.

2. Consider the Bottom Conditions of Places Where You Usually Anchor

The conditions of the river bottoms, where you usually fish and anchor, will considerably influence your choice. If you are not sure or are anchoring in different places with varying bottom conditions, get a multi-purpose anchor.

Such anchors will not have so many problems when anchoring in many different kinds of river beds. They can set and hold in mud, rocks, hard sand, weeds, and irregular structures.

3. What Is the Speed of the Current?

Many rivers indeed have calmer currents. But there are also some rivers with currents that move fast. So, think about the average current conditions in places where you usually anchor. The characteristics of river currents can influence your choice, too.

Naturally, an anchor that can hold a boat in a river with a swift current can also hold it in calmer currents. So, it is wiser to get a storm anchor. It will hold your boat securely, whether it is anchored in a river with a calm or fast current.

4. Consider the Rated Holding Power of the Anchor

You already know the size and weight of your boat. Now, you need to choose an anchor that can hold that size and weight. Refer to the anchor sizing tips of the river boat anchors that you are considering.

But remember, it’s not always true that the heavier the anchor, the greater is its holding power. Some anchors only weigh 5 pounds, but they can hold a load of up to 1,000 pounds.

5. Consider the Materials

Another consideration is the material construction of the anchor. If possible, get an anchor made of sturdy and durable materials and are highly resistant to corrosion.

6. Consider Its Convenience

Generally speaking, an anchor that can be easily deployed, retrieved, and stored will get the thumbs up.
