Sea anchor
Modern commercial sea anchors are usually made of cloth, shaped like a parachute or cone, and rigged so that the wider end leads and the narrower end trails. When deployed, this type of sea anchor floats just under the surface, and the water moving past the sea anchor keeps it filled. Some varieties are cylindrical, with an adjustable opening in the rear that allows the amount of braking to be adjusted when deployed.
Anchor coinage
The anchor coinage was a series of four denominations of silver coins issued for use in some British colonies in 1820 and 1822. The name comes from the crowned anchor that appears on the obverse of the coins. The denominations were sixteenth, eighth, quarter and half dollars, indicated by the Roman numerals XVI, VIII, IV and II on each side of the anchor. The reverse design was the royal coat of arms.
