Important Information about Dock Lines for Boats

When at the marina, MI boaters want to inspect all of the elements of their boat, including the dock lines. You want to know more about dock lines in general, how to tell when they are in good condition and the various materials that are used. This helps to ensure that you are making the right choice for your boat and the docking needs that will help to keep it secure when it is at the marina.

Exploring the Materials

Nylon is one of the most popular material choices when it comes to creating dock lines. In some cases, they are straight nylon, while in others; it is mixed with another type of fabric, such as polyester. When combined with polyester, the dock lines tend to have a better stretch to them. This is good for all boats, but especially those that are larger in size and need to be adequately held in place when tied to a dock, pier, slip or a seawall. The three primary reasons nylon is such a solid choice when it comes to being a dock line material includes that it is stretchy, strong and heavily resistant to being damaged by sunlight.

Polypropylene is another option and some people choose it because of its ability to float. However, it tends to be slick and stiff. So, while it definitely has some benefits, nylon is often considered to be the better choice.

Looking at the Construction of the Lines

When you are looking at the different dock line options, you will find that there are two primary ones available when exploring nylon material choices. This includes a three-strand twist and a braid. The braided type comes with a number of benefits, such as not tangling often, resisting abrasion and it is also often considered to be the stronger option. However, on rough pilings, braids can snag.

The three-strand twist does not snag. It tends to be more cost-effective and you can easily splice it. Compared to a braid, it is also often considered to be a stretchier choice.

Protecting the Lines from Chafe

Some dock lines will come with items that can help with this. However, no matter the material of your lines or your methods, chafing happens eventually. This does not mean that your lines are poor in quality or not being used right. Just replace as necessary.

Dock lines are important for boats. There are different materials and the needs of all boats are going to be different. With this information, it makes it a lot easier to choose a dock line that will secure your boat to the marina in MI to keep it safe.
