XVII. MOORING, ANCHORING, AND TOWING
CAUTION! (ISO 15084:2003)
.
● The anchor points for anchoring and/or towing are the 2 fore cleats, which have a breaking
strain of approximately 9000 kg. Rear and mid-ship cleats can also be used for mooring. They
have a breaking strain of approximately 6000 kg.
● The breaking strain of the lines/chains should in general not exceed 80% of the breaking strain
of the anchor points, i.e. in this case a galvanized chain of 12mm and a polypropylene line of
22mm max.
● Always tow or be towed at reduced speed. Never exceed the hull speed of a displacement
boat in tow.
● The tow line should always be made fast in such a way that it can be released when under
load.
Responsibility
It is the owner/operator’s responsibility to ensure that the mooring lines, towing cables, anchor
chains and lines, together with the anchors, are suitable for the boat’s intended use, i.e. that the
lines or chains do not exceed 80% of the breaking strain of the corresponding anchor point.
Moreover, the owner must take into consideration all necessary actions when attaching a tow line
to the boat.
