The re-righting performance of three yacht hulls has been assessed experimentally. The three hulls are considered to be representative of modern racing yachts. It has been shown that two different experimental techniques provide the same relative results between the three hulls, leading to the same conclusions. Correlation of re-righting performance with basic hydrostatic parameters has been shown for these three hulls, however a simple case when this correlation is non-existent is noted.
