ABSTRACT:
An improvement in a known cable ship, including a drum type cable engine installed on an inboard deck and a bow sheave disposed at a top portion of a bow for receiving a communication cable payed out from a drum of the cable engine, resides in the provision of an intermediate sheave disposed between the bow sheave and the drum type cable engine. In order to dispose the bow sheave at a high position with respect to the water surface, the upper side of a guide section of the intermediate sheave is positioned at a higher level than the upper side of a guide section of the drum of the cable engine. The communication cable extends from the cable engine via the intermediate sheave up to the bow sheave. Preferably, a tension meter for the communication cable is disposed between the intermediate sheave and the bow sheave.
