Reference 1 describes tests of sailing yacht models in breaking waves. For these tests the largest model was 16.1 inches in length. It was considered desirable to repeat these tests with larger models to improve the accuracy and to confirm that there are no effects of scale which would significantly alter the conclusions. . For the tests described in this section, a model with an overall length of 36 inches was used, thus the effect on Reynolds No. was more than doubled from the previous tests.
The object of these tests was to investigate the dynamic behavior of a sailing yacht model when it was struck by a breaking wave, to evaluate the effect of using a drogue, to obtain information on the loads on the boat and drogue, and to provide data for a computer simulation which would aid in interpreting and projecting the test results.
