anchor = a metal device lowered on a line or
chain and used to secure a
vessel to the sea bed.
Also used to secure nets. Anchors have flukes
(points
that dig into the bottom or grab rocks;
the flattened part is called a palm)
connecting
by arms to a crown, a shank (a vertical bar)
rising from the crown, many also
have a stock
(a horizontal bar that prevents rolling over)
which passes through
an eye, and a ring (where
the rope or chain is attached). There are many
different type and sizes
of anchors, e.g. see
killick, Admiralty
pattern anchor, ice anchor
and trawl anchor....more
