Strains and pressures were measured in the antipitching fins on USS COMPASS ISLAND (EAG 153) and were correlated with simultaneous measurements of sea state and ship motions. A maximum principal stress of 14,000 psi was obtained when the fins slammed in a State 6 head sea at a ship speed of 18.8 kno...
