Concise Bible Dictionary:

The anchors used by the ancients were in shape somewhat like the modern ones, as may be seen on some of the coins. When Paul was on his way to Rome, four anchors were needed to hold the ship (Acts 27:29-30,4029Then fearing lest we should have fallen upon rocks, they cast four anchors out of the stern, and wished for the day. 30And as the shipmen were about to flee out of the ship, when they had let down the boat into the sea, under color as though they would have cast anchors out of the foreship, (Acts 27:29‑30)
40And when they had taken up the anchors, they committed themselves unto the sea, and loosed the rudder bands, and hoised up the mainsail to the wind, and made toward shore. (Acts 27:40)
). The anchor is used metaphorically for the hope set before the Christian; it enters into that within the veil, and is sure and steadfast. It was a great thing for the Hebrew believers to have their eyes turned to heaven; the anchor of their hope was there; no matter what storms they might meet with, the realization of their hope was certain if set on Christ (Heb. 6:1919Which hope we have as an anchor of the soul, both sure and stedfast, and which entereth into that within the veil; (Hebrews 6:19)).

KJV Usage:

From Manners and Customs of the Bible:

Ancient vessels had not so heavy anchors as ours, and therefore carried more.
It was customary to anchor ancient ships by the stern, though they were sometimes anchored at the bow. The anchors were carried in the skiff to a suitable distance from the vessel and there dropped. In modern times ships of-war in action have sometimes been anchored from the stern. Lord Nelson pursued this plan at the battle of the Nile, and at the battle of Copenhagen. See the account in Alison, History of Europe, (Edition, Harper) vol.1, p. 513; vol. 2, p. 154.
