Hendrick van der Heul was a privateer and quartermaster of William Kidd. He later became captain of the Octavius.
During his captaincy, Hendrick received a letter from Kidd, in which he confided that he was holed up in Boston, and that a particular group was intent on obtaining his Shard of Eden.
Hendrick died when the Octavius became stranded in ice, while looking for the Northwest Passage.
