Any experienced mariner knows the anchor is a vital part of any vessel. Without it, ships can be dragged and tossed around by the waves and, if you spend the night on the water, you may wake up far away from where you settled down. Therefore, for new or seasoned mariners, we reviewed the best sea anchors that will keep your ship locked in place through whatever conditions you need to overcome.
For those who just purchased their first boat, or are looking to purchase their first boat, we answered some frequently asked questions about anchors below.
1. What Is a Sea Anchor?
It is a piece of equipment that is attached to your boat by a chain or rope and then thrown overboard, usually underwater, to secure your boat into place. They come in many shapes and sizes that change depending on how deep you cruise and what type of surface the bottom is.
2. What Does an Anchor Do?
It prevents your boat from moving with the waves or current when your engines are turned off. This is important as without an anchor your ship may get slammed into a reef, get dragged out to unfamiliar waters or even pushed onto the shore.
3. How Does It Work?
It works by grabbing hold of the water’s floor as your boat is moved about. The sharp angles drag through the sand or rock until they either find a perch or dig deep enough to hold almost still. Second, the chain creates friction that counters the motion of the ocean. While it is impossible to completely negate any movement, anchors will keep you relatively in place, allowing you to sleep comfortably overnight, scuba and swim off the side or continue to attack a great fishing hole.
4. Where Can You Buy One?
Anywhere boats are sold or online. We provided the links to all our sea anchors below.
5. What Does a More Expensive Anchor Do?
Usually, paying more money for an anchor will guarantee you a more reliable and long lasting product. If you like to explore deep waters and the open ocean often, then we recommend spending a little more to guarantee you an anchor that can handle the rough ocean conditions. If you are just cruising on a calm lake, then a cheaper anchor will probably be more than enough for you.
6. Do You Need Multiple Anchors?
If you are going to different areas with different seabeds, then it may be in your best interest to have multiple anchors. An anchor that works best with a sandy floor may not work as well on a rocky floor.
