Docking Your Boat

Do you want help with what docking/mooring line that is best suitable for your boat?

Docking/mooring your boat for a storm

Docking/mooring your boat for a storm is a very good old maritime rule, and one that should always be followed. It is very important to dock your boat properly and correctly so it can not escape and drift out to sea or out on the lake. Remember that different ports, docks and other situational occurences can vary significantly and therefore what is best practice at one site may not be best practice at another. Also remember that docking/mooring a boat can be difficult even for the most seasoned boat owner.


The line used when docking/mooring should have the correct dimension suitable to the boat’s weight. You can find which dimension is suitable for your boat under each respective docking line, see all the docking/mooring lines we offer here. The line should be able to withstand chafing, jerking and the sun’s UV-damage.

Our innovative docking lines Storm & StormX are equipped with two pieces of wear protection, one at the eyelet and an adjustable one along the line in order to provide maximum protection against chafing.

StormX has a braided casing consisting of 100% polyester silk which is optimal as this material sinks in water and you wont need to worry about a boat neighbor crossing over your line. The material is also maximum UV-protected. This docking/mooring line has an elastic core which means you do not need any additional shock absorbers, thimbles or shackles. It also works excellently when mooring (long-term).

Storm is a 3-stranded line made of 60% polyester and 40% shock absorbing fiber. The entire line length consists of this shock absorbing fiber which makes it extra durable and suitable e.g. when taking a boat through the lock. The docking line Storm has also won Best-in-Class several times.

If the docking line becomes damaged you need to exchange it immediately.

Dock without shackles or shock absorbers

With our docking/mooring lines Storm and StormX you, as we’ve mentioned previously, do not need any additional shock absorbers since the lines themselves acts as one. You also do not need to purchase any shackles when mooring if using our docking lines. Instead place the line through itself with the help of the eyelet. There is also wear protection which protects the line against chafing and other wear-and-tear.

Mooring at a dock

Mooring at a dock is usually done with the aid of Y-beams or bollards. When mooring/docking using a Y-beam you need to keep in mind whether it is one or two beams, as you can see illustrated below.

It is also important to keep in mind the water depth, which can vary significantly, when mooring/docking. Otherwise the strain placed on the line can become too much if e.g. the water level significantly lowers. If the water level increases there is risk of slacking lines and more movement of the boat.

When docking/mooring through a mounting it is important that the line always comes through the mount from below. See below image. This because the line can get caught under the mount when leaving the dock. Also keep in mind that the wear protection always should run through the mount in order to protect the line from chafing.

Docking/mooring boat between dock and buoy

When mooring at a dock with the help of bollards you need to make sure all of them are correctly and properly fastened/beaten down. Bollards located at the stern of the boat that are in deep water can move around which can in turn inflict damage on your boat.

When docking your boat at a dock with the aid of a buoy you need to know the water depth, which should not be more than 6m. If it is too deep the buoy chain becomes so long that the boat berth is difficult to control. Mooring/docking with a buoy should be avoided if many boats are located very close to each other at the same dock, in order to minimize the risk of the boats damaging each other.

When docking your boat with the aid of a buoy you need: a buoy weight with a loop bolt located at the bottom, chain or a docking line, a buoy that can easily carry the chain but not so big that it is pulled the surface during heavy strain.

Investigate the sea/lake bottom thoroughly before sinking the buoy weight so there are no major inclines/declines or any rocks under the boat. If there are this can make the buoy move to a different depth if the sea/lake bottom shifts.

Also remember to always use fenders. Here you can find the fenders we offer.
