Tension on a cable

  1. Oct 28, 2009 #1
    A cable is being deployed in the following scenario in the ocean. It is snapping coming around the bicycle wheel on the stern of the ship. What should be looked at to minimise the amount of tension on the cable?

    *EDIT* The boat should actually be going the other way since it is picking up the cable

    From what I know the least tension will be to try pick up the cable with the boat vertically over the point on the cable where it leaves the sea floor. Will the speed the cable is picked up effect the tension? It means the 1.4km of the cable is in the water column for a smaller amount of time, is this a significant variable to effect tension? How will waves and swells effect the tension on the cable? When the boat rises due to swells surely that will increase the tension on the cable and thus picking up the cable in calm seas is more desirable?

    Any thoughts on this issue?
