Shipwrecks, with their loss of life and treasure were common in the early days of maritime trade. Incomplete charts were updated as new reefs, rocks, and saltings were discovered and named after the vessels unfortunate enough to have discovered them. Aids to navigation were few and far between and many were ineffective at night or were dragged off station by storms and currents. Prior to radar vessels steamed blind through fog sounding their foghorns in the hope that collisions might be avoided.
Other than San Pedro sailing out of San Francisco, each of the vessels listed here were owned by a steamship line operating out of Victoria.
