Bare Resistance of the Delft Systematic Yacht Hull Series. Proceedings:211 International Symposium on 'Yacht Design and Yacht Construction' (14th). Held in 211 Amsterdam on November 11, 1996

摘要

The data of the Delft Systematic Yacht Hull Series published so far have always211u001ebeen derived of experiments carried out with the hulls with their appendages, 211u001ei.e. keel and rudder. Obviously to be able to perform tests with models of 211u001esailing yachts in the heeled and yawed conditions it is inevitable to add these 211u001eappendages necessary for the side force production. Only in the upright condition 211u001eit would make sense to carry out experiments with bare or unappended hulls. To 211u001eshorten the time needed for the experiments on the original series only appended 211u001emodels were tested and for the sake of consistency throughout the series the 211u001ephysical dimensions of the keel and rudder, used during the tests, have not 211u001echanged throughout the testing of the entire series, which spans a period in time 211u001enow of roughly 25 year, i.e. from 1974 to 1996.
