How To Choose The Best Boat Anchor Rope – Buying Guide
There are two types of anchor ropes: laid/twisted and braided. The braided rope type is stronger and more flexible than twisted rope but has less stretch and is more difficult to splice than twisted rope. A laid/twisted rope is easier to splice and is often less expensive. If offers more stretch than braid but is stiffer and more likely to kink.
Rope can be made out of many different materials but by far the most common is nylon as it’s very strong, flexible which is great for shock absorption and light thus easy to use. It also sinks, which is what you want with a boat anchor rope. Synthetic materials like polyester and polypropylene are also used.
Breaking Strength and Max Safe Working Load
A rope’s breaking strength is the amount of weight that could be imparted on it before it breaks. Manufacturers give you the maximum breaking strength to help you gauge the strength of the rope. The max safe working load is a fifth of this number. Calculating the max safe working load will help you determine the suitability of rope for your boat anchor.
Boat size plays a major role when it comes to the anchor rope choice. The bigger the boat you have, the more stress it will put on a rope and the thicket the rope should be. As a general rule of thumb, you need an eighth of an inch of rope for every nine feet of the boat.
Q: What Anchor Rope Do I Need?
You need 1/8" of anchor line diameter for every 9 feet of boat length and a length 8 times the depth of the water you’ll be anchoring in. For a 27' long boat, this translates to 3/8" diameter, 5/8" for a 45' boat and 3/4" for a 54' boat. If you’ll be anchoring in 10 feet deep water, the rope should be 80 feet long. This is the general rule of thumb but you should also take into consideration the conditions you expect to be anchoring in.
Q: What Type Of Anchor Rope I Need?
The type of anchor rope you need depends on the type of boat you have and the type of water you will be traveling in. You need a rope that will be able to cope with the weight of your boat and also the rope length needs to be matching the water you’re traveling over.
Q: What Is An Anchor Rope?
An anchor rope is the rope you use to connect your boat to your anchor. It should have a lot of strength to withstand the constant tugging and ability to resist the harsh marine elements such as mildew and UV light.
Q: What’s The Difference Between Braided And Twisted Rope?
Braided rope is more flexible, stronger and easier on your hands but a twisted rope is easier to splice, cheaper and will have a higher degree of stretch. Braided rope is the more popular option but twisted rope is the best option if you're using a windlass and chain, and doing your own splicing.
Q: How Much Anchor Rope Do I Need?
For every foot of water you’ll be anchoring in, you need eight feet of rope. This is because an anchor doesn’t go straight down but instead drags along the bottom until it hooks on.
Q: What Is The Best Type Of Anchor Line For Most Situations?
Three strand or double braid nylon rope is the best boat anchor rope for most anchoring, docking and mooring situations. It has great strength, stretches to absorb shock and tugging, and is accessibly priced. It's also easy to handle and resists marine elements better than other types of anchor lines.
