1.6.3. Towing
The anchor line can be used for towing. However, a special towing line of the same strength is
more suitable. Fasten the towing line in the shape of a bridle to the two bow cleats. In case of
longer towing distances wind a rope of the same strength around the entire boat in order to
distribute the towing forces. Other points, e.g. the guardrail or the mast step, are not suited for
towing. A towing line may only be attached in such a way that it can be slipped under load.
Abrasions must be avoided!
Please note that, when towing, the speed of both the towing and
the towed vessel must be below the so-called hull speed,
otherwise the towing forces can damage the boat. This boat’s hull
speed is approx. 7.5 knots (=13.9 km/h).
Depending on the weather conditions, swell and depth of the water, it could be necessary to
reduce this speed considerably, since the occurring loads can lead to damages.
1.6.4. Mooring
The cleats arranged on the bow and stern, which are sufficiently dimensioned to deal with the
normal forces in protected ports, are used for mooring.
Use the onboard winches or cleats in pairs to position the boat.
In case the boat is unattended for a longer period of time, protect the mooring lines against
wearing through and unintentional detachment.
Before starting a voyage, the skipper must make sure that
•
the anchor and the chain are clear;
•
the necessary docking and towing lines are on board and in
working order.
Only use the cleats and winches to moor the boat. The guardrail
and other points on deck are not suitable.
