In determining the scope of anchor line to pay out when anchoring a small boat, one must consider the __________.

Correct Answer: Option A — depth of water, including tidal differences

When determining scope, the total depth must include the charted depth plus the height of the tide. Failing to account for tidal rise can result in an insufficient scope, causing the anchor to drag as the water level increases and the vessel's position shifts relative to the seabed.
