When it comes to the boat, anchor plays a crucial role in holding a boat. But, what makes it hold is a ROPE or a CHAIN. While choosing or buying a rope, you shouldn’t rush yourself.

After researching for hours about the good ropes for anchoring a boat. I found Extreme Max 3006.2252 BoatTector Premium Double Braid Nylon Anchor Line with Thimble(linked to Amazon) (don’t worry, it will open in new tab)is the best rope for anchoring a boat. These ropes are made up of nylon material, which is very strong and will not float in the water.
Especially when it comes to a boat under 30 feet, this 3/8″ Extreme max rope is perfect for anchoring. The cost of the product is also not expensive, it is reasonably good. It is available in the range from 150 – 600 feet long(45m – 182m).
| Rope diameter (inches) | Load Limit (lbs) | Boat length (feet) |
| 3/8″ (0.9525 cm) | 4500 lbs | up to 27 feet |
| 1/2” (1.27 cm) | 8300 lbs | up to 36 feet |
| 5/8″ (1.5875 cm) | 13400 lbs | up to 45 feet |

Check my article on Choosing ropes and chains for anchoring a boat (don’t worry, it will open in new tab). In that article, I mentioned all the things you need to consider while buying anchor ropes and chains.
Consider these things while buying an anchor rope
The essential thing you should consider while buying an anchor rope is the material of the rope. Whenever you are buying a rope, don’t buy polypropylene rope. The issue with polypropylene rope is it will float in the water, which may cause some problems to other boaters.
The first thing you should consider while buying a rope is to check whether it will float in the water or not. If it is not floating, then it is fine. If the rope is floating in the water, it will create problems for other boaters.
Polypropylene rope (pool rope or ski rope) is a very lightweight synthetic so, it will not sink in water. Since it doesn’t absorb water, it resists rot, mildew, oils, acids, etc. Polypropylene can stretch when under load and can be uncomfortable to handle since it is stiffer than natural fiber.
Like, the rope may be caught up in some other boat propeller, it may cause a severe problem for you or to your boat. Nylon would be the best material for a rope because it will stretch, if any wave comes, nylon rope will stretch absorb the shock, and goes back to normal.
Any rope that doesn’t float in the water is good for anchoring the boat. The polypropylene will not absorb the water so, it will float in the water, causing problems to other boaters.
If you are anchoring your boat in a crowded area surrounded by boats, then you shouldn’t use the rope which floats. If you won’t go to a crowded area, then you can buy any rope.
Now, that you have selected the material of the rope. Let us see which rope is better (solid braid or three-strand rope).
What type of ropes you should buy for anchoring a boat?
There are two types of ropes used for anchoring a boat.
- Solid braid rope
- Three-strand rope
Both of the rope types are good for anchoring the boat, each type of rope has its advantages and uses. First, let us see about the solid braid rope, and then we will see a three-strand rope.
Advantages of solid braid rope while anchoring a boat
The advantages of solid braid rope are it is flexible and strong. Knots with a solid braid rope is much more effective than any other ropes. But the solid braid is a bit more expensive than a three-strand. The only problem with the solid braid is it won’t slice up as 3 strand rope.

The main advantage of the solid braid rope is the elasticity. It is more elastic than other ropes (but, not more elastic than three-strand). The nylon will absorb all the shocks from the waves in the sea and stretches accordingly.
Nylon braided rope is very suitable for various uses. Nylon rope will stretch when sudden pressure is applied, but it will not do so at the expense of its durability. This quality makes it an excellent option for construction or climbing.
Most people prefer to use a braided rope for mooring lines primarily because it has a better feel in the hand. But, a solid braid can be used for anchor rope as well.
In solid braid rope, there are two types of ropes
- Single braided rope
- Double braided rope
The difference between a single braided and double braided rope
The difference between a single braided and a double-braided rope is a double-braided rope is a single braided rope, which is braided on the top (exterior) with another layer. The inner braid rope is made from a stronger material, while the outer is a more abrasive resistant material.
Which one is more efficient, Single braided or double braided rope?
Double braid rope is more efficient than a single braid because the inner braid rope is made from a stronger material, while the outer is a more abrasive resistant material. So, combined will increase the strength of the double braided rope. You can use a double braid for anchoring a boat.
If you thinking to buy a solid braid rope for anchoring your boat, then the better option would be a double braided rope.
Advantages of three-strand rope
The advantages of a three-strand rope are these ropes are a bit less expensive than a solid braid. We can slice the three-strand rope better than a solid braid rope. Three-strand rope gives more grip than a solid braid rope and more elastic than a solid braided rope.
When it comes to three-strand rope, Extreme Max 3006.2303 BoatTector Twisted Nylon Anchor Line with Thimble(linked to Amazon) (don’t worry, it will open in new tab) is the best three-strand rope. This is the best three-strand rope for anchoring your boat. The image is linked to Amazon.
Twisted rope is generally preferred for anchor rodes because of its slightly greater elasticity. I find that it’s a bit easier to get a good grip on wet three-strand than wet braided rope.
- It costs less than a solid braid
- Easy to splice
- More elastic (stretches more)
What length and size rope you should buy?
It depends on the depth of the water too but, a 3/8″ (0.9525 cm) diameter with 250 feet (76.2 m) or more in length is best for a boat under 30 feet. If your boat is small, no problem, it is better to protect your boat with some extra strong rope. It is good to have extra length, don’t buy too short one.
The length of the rope depends on the depth of the water, it depends on what depth you will drive the boat. There is a rule of thumb for selecting the length of the rope.
If you are using the boat in calm water and there are no huge tides, then 5:1 scope is sufficient. For every one meter in length, you should use five meters length rope. This will be enough for small boats or dinghies.
But in general, if the water depth is more, then go for 250 feet. If the water depth is less, then go for 150 feet or 200 feet length ropes. The rule of thumb for selecting a rope length won’t work properly because the depth changes from place to place, and it is hard to tell.
So, buy extra length rope based on depth and scope. If you are using a boat under 30 feet, then go for 250 feet length rope for anchoring.
Other best rope for anchoring a boat
If you think Norestar is a bit expensive then go for Extreme Max 3006.2264 BoatTector Premium Double Braid Nylon Anchor Line with Thimble(linked to Amazon) (don’t worry, it will open in new tab) The extreme max rope is also good for a boat.
If you are buying an Extreme max rope than go for a half-inch diameter rope. When it is compared to Norestar, the Extreme max rope load limit is less. So, it is better to go for 1/2″ rope.
| Rope diameter (inches) | Load Limit (lbs) | Boat length (feet) |
| 3/8″ (0.9525 cm) | 3350 lbs | up to 27 feet |
| 1/2” (1.27 cm) | 4380 lbs | up to 36 feet |
| 5/8″ (1.5875 cm) | 8430 lbs | up to 45 feet |
| 3/4″ (1.905 cm) | 10500 lbs | up to 54 feet |
Conclusion
Both brands are very good and have a high-quality standard. While buying, don’t go for too expensive rope. I would prefer you to buy Norestar Double Braided Nylon Anchor Rope/Line with Thimble(3/8″ thickness). This is an excellent product.
