Dominican Republic Anchor Data Analysis


Anchors of the 15th and 16th century are typically square in cross section. The shank is the largest piece of iron to which everything else is attached. The arms of the anchor are typically attached at the bottom of the shank. At the end of the arms are flukes. These are used to dig into the ground and hold the anchor in place. The proportions of the anchor give clues as to the time period from which it came.

The Caballo Blanco Anchor

Shank = 11 feet

Arms = 2.73 feet

Angle between the shank and the arms = 69 degrees +/- 4 degrees

The Santa Maria

Angle between the shank and the arms = 65 degrees +/- 4 degrees

  • It is possible that both the Caballo Blanco anchor and the Santa Maria anchor are from the same time periods. However, the angles between the shank and the arms don't fit the description of anchors before 1550.
