DOCK LINES


The Best Custom Boat Lines, Custom Colored Ropes, & Special Assemblies made to Your Specifications

Bow, Stern, and Spring Lines - Most average sized boats can be moored using two groups of dock lines (4 dock lines). For the first group there is one each of a Bow Line and a Stern Line, which are +/- 2/3 the length of the boat, and are used to make fast the bow and stern to the mooring. For the second group there is an After Bow Spring Line and a Forward Quarter Spring Line, which are +/- the same length of the boat. The spring lines cross each other forming an x-pattern to the mooring. A simple rule of thumb is have two long dock lines and two short dock lines in addition to any other mooring lines.

Breast Lines - Larger and heavier boats use the same lines mentioned above, but can also use relatively short lines that connect direct from a boat cleat to the nearest cleat directly across on the dock approximately at a 90 degree angle. Breast Lines are often employed on houseboats in a slip. Breast Lines are sometimes substituted for the use of Spring Lines.

Large Boat in a Slip - When any boat is moored for long periods of time in a slip, use the classical dock lines techniques already mentioned, but often dock lines are utilized on both the port and starboard sides of the boat. Therefore, a large boat may need two bow lines, four spring lines, and two stern lines. Add breast lines as required. Slip Dock Lines are often short due to the close proximity of the cleats on the boat and the dock. Chafe Protection for slip dock lines is highly recommended.

Concerning The Dock Line / Mooring Line Table Of Part Numbers Please consider that most of our dock line requests are for double braid nylon construction; however, we can generally utilize any of the rope materials described in Chapter 2 “Rope Selection Guide” and Chapter 5 “Bulk Rope”. Secondly, there are additional diameters and rope lengths available upon request. Note that a 300 foot minimum production run may apply. Do not see what you are looking for, just ask

colored double braid nylon dock line house boat

A custom colored double braid nylon dock line for a house boat in a slip. For long term mooring applications please consider to have the eye splice covered with chafe gear “covered eye”. If the cleat’s fairlead hole is too small for the rope to be pulled back through the center, consider to have the eye splice sized to be about 2/3 the overall length of the cleat.

A double braid nylon dock line for a boat in a slip. In this case, the boat’s pop-out cleat fairlead hole is large enough for the covered eye splice to be pulled back through the center for a secure connection.

Measurements
Please consider the sketch of a dock line or any mooring line pulled taught as to measure the overall length (OAL) of the line Secondly, consider the sketch of the eye splice pulled taught as to measure the length / size of the closed loop “L”. The eye splice size / length is measured this way as to equal the one way length measured from the splice to the tip / far end / crease.
The total length of rope required to make the eye splice would be 2 x L + bury of the splice, where the bury is often equal to 18 x the diameter of the line. The amount of chafe guard to cover the eye splice would be 2 x L.

 

Heavy Duty Cleat boat - dock lines If the cleat’s fairlead hole is too small for the eye splice to be pulled through, select the length of the eye splice to be 2 inches less than the overall length of the cleat horns for a snug fit around the cleat.

If the cleat’s fairlead hole is adequately sized for the eye splice to be pulled through, select the length of the eye splice to be 1.5x the overall length of the cleat horns for a secure eye splice fit.
If chafe gear is used to cover the eye splice (covered eye) additional clearance is required.
Dock Lines - heavy duty stainless steel dock cleat

If the dock line passes through the boat’s chock hole and subject to chafing, chafe gear can be sewn in place along the dock line’s wear area.

These guidelines are subject to verification to the boat owner’s actual equipment dimensions. Standard for double braid rope (yacht braid), is the whipping of the bitter end and the throat of the eye splice.  The owner may choose different whipping colors as to distinguish between different lengths of lines.  Available whipping twine colors include white, black, natural, red, blue, green, and yellow.


Additional diameters and rope lengths are available upon request. Our standard in-stock colors are white*, black*, and navy blue purple*. However, we often have additional solid colors available like red, royal blue, hunter green, teal, and several remnant combinations in any given diameter as our inventory fluctuates daily. Colors and combinations that are not normally in-stock, require a total new production run of at least 300 feet in a specific diameter. Give us a call as our colored rope inventory changes on a daily basis.

Note: All lines are custom made-to-order and further customization can be specified (i.e. double ended lines). Double Braided Lines are whipped and sewn at the throat of the splice and at the bitter end.

Dock Line Selection Process
1. Choose Rope Diameter
2. Choose Rope Length
3. Choose Rope Color / Combination
4. Choose Loop / Eye Splice Size (9”, 12”, 18”, 24”, etc). Measure your cleats (perform test t) to determine what loop / eye size will work best to secure your boat. We assume the other end of the dock line is bitter.
5. Choose Optional Black Nylon Cordura Chafe Guard “Covered Eye”. Additional locations upon request (i.e. chock protection). Chafe Guard is strongly recommended for Long Term Mooring applications.
6. Choose Quantity of Dock Lines
7. Repeat Selection Process for each type of Dock Line (bow, stern, spring, mooring lines, houseboat shore lines, etc)
