Profit is connected with time. The longer a ship is exploited the greater profit she yields. Then famages cause not only the direct losses of supposed profits that the greater, the longer is ship repair time.

The calculation presented in this article has been worked out in different variants including offer repair costs in foreign and country ship repair yards. The place and extension of average, the cost of towage and the waste of time are also considered in this paper.
