Abstract:

This report describes an experimental investigation of the behavior in calm water and in waves of a model equipped with extremely large bowand stern-bulbs. Results of the calm-water resistance tests are presented for the model without bulbs, and for the model with the bulbs in three different configurations. Results are also presented for tests of one-model configuration both in regular and irregular waves. On the basis of the test results, the performance of the large-bulb ship is evaluated in comparison with other hull types. Practical advantages and disadvantages of the design concept for naval application are discussed. Author
