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

Mooring Pendant (type of mooring line) is a relatively short length of line used to connect a vessel to a mooring buoy (or mooring) usually via the boat’s bow eye or bow cleats. The boat can free wheel about the mooring depending on the wind direction.



Buoy Field Mooring - When a boat is moored in a buoy field, a custom mooring line can be utilized i.e. a Mooring Pendant, which have characteristics of both dock lines and anchor lines and the associated hardware connections. A typical line will have a dock line eye splice (covered eye) for connecting to the boat’s cleat or a hard eye for connecting to the boat’s trailer bow eye via hardware. On the other end, a hard eye with a stainless steel swivel hook, spring clip, anchor swivel, and or shackle for making fast to the buoy connection. The mooring line might well be fitted with a buoy or rope float(s). Mooring Pendant Bridle assemblies have the shape of a V or Y depending on the Owner’s preference.



Thimble Eye Splice — Mooring Pendants like anchor lines are provided with a thimble eye splice on one end (even both ends), which provides rope chafe protection for the connection to a shackle, swivel eye hook, anchor swivel, or spring clip. The hook or clip connects the thimble eye of the mooring line directly to the bow eye of the boat being moored and or the mooring buoy. The mooring line might well be fitted with a rope float(s). Simply select the required splices and hardware for each end of the mooring pendant as required for your application.



Permanent or Shackled Connections — The connection between the mooring pendant and the swivel eye hook or shackle can be a permanent spliced connection (the hook is connected directly to the thimble) or a temporary connection (the hook is connected to the thimble via a shackle).



Covered Eye Splices — To protect an eye splice from chafing on a cleat, the eye splice can be providing with chafe guard tubing. The same chafe guard tubing can be also installed below the eye down the line to protect the rope from chafing against hawser holes, etc.  Several Chafe Guard Options are Available.



Hardware — As the working load limit of the Mooring Pendant increases, the type of hardware that may be used becomes more critical (HD Thimbles, Quick Release Snap Shackles, and Trigger Release Shackles). We have both galvanized and stainless steel hardware.



Freeboard — Is the distance from the water line to the deck. For boats with a low freeboard, it is usually possible to have access to the trailer bow eye in order to connect a single leg mooring pendant. Motor Yachts and Sailboats with a high freeboard and no ease-of-access to trailer bow eye and or they do not have one, it is then necessary to use the bow cleats in order to connect the mooring bridle legs to the mooring system.



Overall Length — The rule-of-thumb for the OAL of the mooring pendant assembly = 2.5x - 3.0x the freeboard minimum unless otherwise directed by the mooring field manager or other AHJ. For Y-Bridle applications, the length of the bow bridle legs is 2x the distance between the bow cleats minimum in order to keep the inside angle formed by the bridle legs at the Y-Point very acute.



Rope Fiber and Construction — Our most popular choice for mooring line applications is Double Braid Nylon Construction (DBN) selected for its shock absorption properties, which we manufacture ourselves on our own rope machines. All our mooring lines are spliced-to-order. The minimum length of rope we splice for DBN is 6ft. If the line is shorter, we then switch to 3-Strand Nylon because the spliced length of the bury is much shorter.



12-Strand Dyneema — Selected for its high strength, high abrasion and wear resistance, but with no stretch and higher cost. Dyneema rope is often used to substitute a portion of a bridle assembly that would otherwise be made from DBN rope. For example the bridle legs or buoy leg will see a reduction of 3/8” in rope diameter as compared to same strength of DBN rope can be realized. We do recommend that some portion of the mooring bridle assembly be constructed from DBN rope in order to provide the desired shock absorption properties.

Rope Strength — The Mooring Line Strength (WLL or MBS) can be made in consideration of the Boat’s Dock Line Size, the Anchor Line / Anchor Chain Size, and or the Mooring Characteristics. We’ll then size the mooring line assembly to match and or exceed these components.



Single Leg Mooring Pendant — As the name implies, a single piece of line is assembled with the required splices and or hardware on each end of the line (bow connection and buoy connection). The mooring pendant might well be fitted with a buoy or rope float(s).



Double Leg Mooring Pendant — As the name implies, two independent single pieces of line are assembled with the required splices and or hardware on each end of the line (bow connection and buoy connection). The mooring pendant might well be fitted with a buoy or rope float(s). Many owners might well specify a Primary Mooring Pendant with all the preferred features and options, but also a smaller diameter and longer length Back-Up or Secondary Mooring Line with only the basic features needed. Another option is to use two full sized independent mooring pendants instead of a spliced bridle arrangement.



V-Shaped Mooring Bridle — Usually for boats with a high freeboard, one piece of line (V-Leg) with a dock line eye splice (soft covered eye) on one end of the line and the other end of the line is bitter. Each for connecting to the boat’s port and starboard bow cleats. Chafe guard can be applied to the middle of the line. A second piece of line (Buoy-Leg) is passed through the first in the middle via a slippery thimble eye splice or soft eye splice. The other end of this line is connected to the mooring buoy via a hard eye splice and hardware. The buoy leg might well be fitted with a buoy or rope float(s). With a long V-Leg, the amount of line paid out can be adjusted at the bitter end. However, the buoy leg can move unpredictable along the V-Leg with severe weather and wave action. This arrangement is not often used for mooring pendants, but more often utilized for towing applications.



Y-Shaped Mooring Bridle — Usually for boats with a high freeboard, two pieces line each with a dock line eye splice (soft covered eye) one for connecting to the boat’s port bow cleat and the other line for connecting to the starboard bow cleats. These two lines (bow bridle legs) are joined to a third piece of line (buoy leg) via soft covered eye splices. At the Y-point, hard eye splices and hardware can be substituted for the soft covered eye splices. The other end of the buoy leg is connected to the mooring buoy via a hard eye splice and hardware. The mooring bridle legs might well be fitted with a buoy or rope float(s). This arrangement is our most popular bridle arrangement, both for mooring and towing purposes.



House Boat Mooring Pendant — The same design concept as the single leg mooring pendant, but applied to a large boat like a houseboat. Larger diameter mooring rope and heavy duty hardware is required for this application. Wire rope can be substituted for fiber rope, but stainless steel wire rope and hardware is recommended. High Performance 12-Strand Dyneema rope is a good choice for this application. The mooring pendant might well be fitted with a buoy or rope float(s).

Anchor Chain Bridles, Anchor Chain Snubber Pendants, and Mooring Bridles — Have the same design concepts as the mooring pendants and mooring bridles described above; however, they are used to provide a degree of shock absorption for a boat’s anchor chain. One end of the line connects to the bow cleat(s), while the other end connects to the chain via a hard eye thimble splice and hardware (shackle, hook, rope, etc.).

CONCERNING CUSTOM MADE-TO-ORDER MOORING LINES — Please consider that many of our mooring pendant 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”. Note there are additional diameters and rope lengths available upon request. All our mooring lines are custom made-to-order so we do not have part numbers for custom assemblies. Do not see what you are looking for, just ask.
