NCHORING MOORING AND TOWING
Mooring, anchoring and towing require specific skills and good seamanship. Always ask
for advice when needed.
It is the owner's and operator's responsibility to ensure that mooring, towing and anchor
ropes, anchor chains and anchors are appropriate for the vessel's intended use and in
good condition. Wear and impact of knots should be considered. Also, see chapter 3.10
(strong points).
Anchoring:
When you anchor or land temporarily in a natural harbour, ensure sufficient water
depth. Drop the anchor at a sufficient distance from shore, allowing time for the anchor
to drop and grip and to release enough anchor rope/chain. The anchor rope/chain length
should be at least 4-5 times the water depth. Choosing the right type of anchor and
anchoring method requires boating experience, ask for advice when needed.
Storm anchor:
If you lose engine power at sea and the waves are strong, keep the boat headed into the
waves by rigging a sea anchor off the bow (below principal figure). If there is no sea
anchor on board, use a canvas bucket or any object that offers resistance.
Mooring:
When coming ashore or mooring to a quay the boat must be secured properly. The
boat, when moored, should withstand high winds and rough seas. The boat should not
be moored with temporary fastenings if the crew is not nearby. Make sure other boats
cannot be damaged by your boat and consider the effect of the wake of passing vessels.
Mooring ropes should be long enough and as horizontal as possible. The boat should be
able to rise and sway without moving sideways. You normally need two mooring ropes
for both bow and stern. Only use the strong point cleats, not the stem eye or secure
eye. The ropes for the bow should be equipped with elastic shock absorbers and the
ropes for the stem should be about the length of the boat. The points of contact
between the rope and the clasps should be checked regularly for wear and tear.
