MODEL SHIP CORRELATION DATA
The extension of model/ship correlation data to other forms of manoeuvre widens the number of variables to be considered. On the evidence available there appears to be some justification in recommending that considerably more attention should be paid to matching the model condition to that of the ship. This means not only achieving correct draught, trim and VCG but also obtaining similar characteristics for the propulsion machinery and rudder operation. At least for the slender ships these factors appear to have more importance than scale effects. For the full bodied forms there is clearly some influence of scale effect which can produce in the model entirely different steering characteristics to those of the full scale ship. This result is not consistent and may be due to the formation or otherwise of trailing bilge vortices on which a separate Committee report has been made. This report has considered some of the information that has been made available during this session primarily because it contained elements of difference from previously reported results.
