INFLUENCE OF DRAUGHT ON MANOEUVRING PROPERTIES FOR DIFFERENT SHIPLENGTHS

The HSVA (the Hamburg tank) has been carrying out investigations on the influence of ship-length on manoeuvring, propulsion, and wake, in experiments with a model of a single-screw bulk-carrier. The parallel mid-body of the model could be varied in length. The Author (of the HSVA) gives an account of the experiments that related to the effect of draught on manoeuvring properties, for different ship-lengths. Kempf standard tests were made at three different draughts (85%, 100%, and 115% of the design draught) and at four different L/B ratios (4, 5, 6, and 7), at a speed corresponding to 16 knots. The results are presented and discussed, and it is concluded that: (i) Increasing the draught of long ships (fast container-ships, frigates, etc.) has little influence on steering properties; reducing the draught has a relatively large influence. (ii)The influence of increased draught is relatively high for ships of small L/B ratio (tugs, etc.). Order from BSRA as No. 49,425.
