Throwbal black 9cm
To throw both precisely and over a long distance, we fill the Throwing-ball with water, so it gets a weight of approx. 335 grams.
Tie a light rope to both the Throwing-ball and the larger heavy mooring rope. Throw the Throwing-ball to the crew waiting on the wharf or quay who afterwards easily can pull over the heavy mooring line and secure it safely to the bollard.
