Docklines are an essential tool for any boat owner, whether you’re a seasoned sailor or just starting out.
They serve as the primary means of securing your vessel to a dock or other mooring point, keeping it safe and stable while you’re not on board.
In this article, we’ll cover everything you need to know about docklines, including the different types of lines available, how to choose the right length and diameter for your boat, and the proper techniques for tying and handling your lines.
What Are Docklines?
Docklines are ropes or lines that are used to secure a boat to a dock or other mooring point.
They are typically made from nylon, polypropylene, or other synthetic materials that offer a combination of strength, flexibility, and durability.
Docklines are available in a range of lengths and diameters, and the type and size you choose will depend on a variety of factors, including the size and weight of your boat, the conditions in which you’ll be mooring, and your personal preferences.
Types of Docklines
There are several different types of docklines available, each with its own advantages and disadvantages. Here are some of the most common types of docklines:
Nylon Docklines:
Nylon is the most popular material for docklines because of its strength, elasticity, and durability. Nylon docklines are available in a range of diameters and lengths and are ideal for most mooring situations.
Polypropylene Docklines:
Polypropylene is a lightweight, inexpensive material that is popular for use as a backup line or for temporary mooring situations.
It’s not as strong or durable as nylon, but it floats and is resistant to rot and mildew.
Double-Braided Docklines:
Double-braided docklines are made from two braided layers of nylon, which gives them extra strength and durability. They are ideal for larger boats or for use in heavy weather conditions.
Three-Strand Docklines:
Three-strand docklines are made from three strands of nylon twisted together. They are less expensive than double-braided lines but are still strong and durable.
They are ideal for smaller boats or for use in moderate weather conditions.
Choosing the Right Length and Diameter
Choosing the right length and diameter of dockline is essential to ensuring that your boat is safely and securely moored.
Here are some tips to help you choose the right dockline for your boat:
Determine the Length:
To determine the length of dockline you need, measure the distance from your boat’s bow cleat to the dock cleat or mooring point. Add an extra 2-3 feet to this measurement to account for any slack or stretch in the line.
Choose the Diameter:
The diameter of your dockline should be based on the weight and size of your boat. In general, the larger and heavier your boat, the thicker the dockline you’ll need.
Most boats will require docklines with diameters between 3/8 inch and 5/8 inch.
Tying and Handling Docklines
Tying and handling your docklines properly is essential to keeping your boat secure and avoiding damage to your vessel or the dock.
Here are some tips for tying and handling your docklines:
Use Proper Knots:
The most common knot used for tying docklines is the cleat hitch. This knot is easy to tie and adjust and is ideal for securing docklines to cleats.
Other knots that are commonly used for securing docklines include the bowline, the round turn and two half-hitches, and the sheet bend.
Avoid Knots in the Docklines:
Knots in your docklines can weaken the line and make it more difficult to handle.
Whenever possible, use a single piece of line that is long enough to reach the dock cleat or mooring point without the need for knots.
If you must tie knots in your docklines, use a knot that is appropriate for the situation and tie it securely.
Properly Coil and Stow Docklines:
Properly coiling and stowing your docklines is important to keep them in good condition and avoid tripping hazards on board.
To coil a dockline, start at one end and make large, loose loops.
Make sure to avoid twisting or kinking the line as you coil it. Once the line is coiled, secure it with a line holder or bungee cord to keep it neat and tidy.
Use Chafe Protection:
Chafing is a common problem with docklines, particularly when the line rubs against a rough or sharp surface. To avoid chafing, use chafe protection devices such as chafe guards or sleeves. These devices can be made from a variety of materials, including leather, nylon, and PVC.
Tips for Docking
Docking a boat can be a challenging task, particularly in windy or strong current conditions. Here are some tips to help make the docking process smoother and safer:
Approach the Dock Slowly:
When approaching the dock, reduce your speed and approach at a slow, steady pace. This will give you more control over your boat and make it easier to make any necessary adjustments.
Use Fenders:
Fenders are inflatable or foam cushions that are placed between the boat and the dock to prevent damage.
Make sure to position your fenders correctly and adjust them as necessary as you approach the dock.
Communicate with Your Crew:
Good communication between the captain and crew is essential for a successful docking.
Make sure to assign roles and responsibilities to each crew member and establish clear lines of communication.
Secure Your Docklines:
Once you have approached the dock, secure your docklines to the dock cleats or mooring point using the appropriate knots.
Make sure to adjust the tension on your lines as necessary to keep your boat secure and stable.
