Shock Absorbing Polyester Dock Lines

Synergy Marine's dock lines offer the very best in protection available for securing your boat to docks, pilings and moorings. The shock absorbing feature is unique and far more functional than any other solution currently available on the market.
All boats while moored are susceptible to damaging wakes from passing boats, waves, current and tides. Finally a product is available to protect your boat with a simple and cost effective alternative to nylon dock lines and springs or external snubbers.

Synergy has coupled the shock absorbing abilities of a multi filament rubber insert with the superior performance properties of braided polyester in an effective and innovative dock line for recreational boats. The polyester remains soft and easy to tie and coil under all circumstances, while providing protection of the revolutionary rubber shock absorber inside.

The rubber shock absorber insert is completely protected from damaging UV rays inside the double 16/8 braid polyester rope. The Jet Black polyester rope is made from high tenacity multifilament yarns that are spin dyed. Each dock line features a hand-spliced 30cm eye on one end and the bitter end is whipped and heat sealed.

The shock absorber dock lines are available various popular lengths and in 4 diameters:

•12mm - 1/2"
•15mm - 5/8"
•18mm - 3/4"
•26mm - 1"

Properties of Synergy's Polyester line:

All Synergy Marine Dock lines are made of high tenacity multifilament polyester. While polyester is the most popular general purpose rope in the boating industry, you will find that there are several types of polyester on the market today - monofilament, split filament, multifilament. The main reasons for choosing high tenacity Polyester multifilament is that it is stronger and more durable than other types of polyester lines.

Synergy's high tenacity polyester has very high strength, and because of the low stretch nature of such fibers, these lines do not shrink when wet. They also have excellent resistance to UV, abrasion, acids, chemicals, oil and will not rot.

Dock & Mooring Lines


What to look for
Dock lines must have a superior combination of strength and stretch:

  • For simplicity, nylon is suitable. Both three-strand and braided construction are common. Three-strand nylon stretches more than polyester, is very abrasion- and snag-resistant compared to polypropylene, and is more affordable than high-tech alternatives. Braided nylon is also a great choice, ofering extra strength, has a nice "hand" feel, and often is available in various colours..
  • Polyester is typically of higher strength than nylon, but has less stretch. Therefore, polyester rope is unsuitable for dock lines. However, when an external dock snubber - or better, an internal shock absorber - is implemented, you can receive ample stretch with huge strength! The extra strength of polyester will give you piece of mind; if a severe storm suddenly blows in, the polyester is more likely to endure than nylon. In this scenario, the rigid properties of polyester may cause minor damage to your boat's (or dock's) hardware in this case, but possibly far less damage then you would incur having your boat blown onto the rocks if your dock lines fail.

Diameter
Let's keep it simple and talk about nylon rope when determining diameter; we recommend 1/8" of line diameter for every 9' of boat length. Larger lines will wear longer but stretch less - remember, some stretch is good! This takes the load off your boat and reduces "line snap" which can damage your boat and its hardware. See the chart below:

Boat Length Up to 27' 28'-31' 32'-36' 37'-45' 46'-54' 55'-63' 64'-72'
Dock Line Dia. 3/8" 7/16" 1/2" 5/8" 3/4" 7/8" 1"

Length
Transient dock lines should be about 2/3 of the boat’s length when used on the bow and stern. Spring lines should be equal to your boat’s length.


Docking and Mooring Techniques

Ah, the fine art of coming to shore. It can be the icing on a perfect day on the water, or a total catastrophe. Indeed, many of the nicknames and embarassing clubhouse anecdotes happen after particularly memorable docking occaisons. Therefore, it's probably a good idea to brush up on your docking technique and how to tie your dock lines properly.

Below are a few brief examples, but we recommend further reading if you intend to become a pro.

Typical docking techniques c/o the Royal Hamilton Yacht Club:

"A well secured boat will have at least four and preferably six dock lines: 2 bow lines, 2 stern lines and 2 spring lines. As a general rule, the length of bow and stern lines should equal two-thirds of your boat's overall length. Spring lines should be slightly longer, approximately the same length as your boat. Spring lines keep the boat snugly near the dock by preventing it from moving fore or aft, while allowing for the rise and fall of the tide. Keep in mind; the position of cleats on your boat and dock may affect the length of the dockline. Unless your boat is unusually heavy or will be subjected to severe conditions, a bow line, stern line, and two spring lines are recommended. If your permanent slip has outboard pilings or a moor as well, you will need an additional bow and/or stern line."

Mediterranean Mooring c/o Sail-World.com:

"Step 1, lower the anchor, well out and then drop back to the dock on a longish warp. If "lazy lines" are supplied, definitely use them instead of an anchor - check other boat's systems before deploying your anchor. After dropping back to the dock, secure the quarter lines. Step 2, adjust all lines so that you are the required distance from the dock."

Note from Clive: When preparing to Med Moor, remember to have your stern lines ready to go - cleated to your boat and handy to be thrown or taken ashore by the helmsman - especially if there are only two people aboard. However, since no one will be paying much attention to the stern lines while backing up, be careful that the stern lines can't fall overboard and wrap around the prop during this critical stage!
