Installation for towing with the boat an enveloped iceberg respectively a resultant water-bag (1). The water-bag (1) has at least at one towing end a tow-bar (9) which is transversal with respect to the towing direction. On the tow-bar (9) are attached rolls (a, b ...) of loops (4) next to each other and used as flexible traction mechanisms. Tow neighbouring loops (4) of a row of loops are connected by another loop in order to form the following row of loops which comprises consequently one loop less until, after forming an acute-angled towing net (5), only one loop or more loops remain to attach the water-bag to a tow-boat. Thereby a uniform distribution of the traction force and a reduction of specific stress in the loop areas are obtained so that the problems of towing the water-bag are eliminated thereby making the towing operation possible with a reduced slide friction coefficient. |
