Show Your Love:

The Anchor Chain Length Calculator serves as a valuable tool for boaters, assisting in determining the appropriate length of anchor chain required for secure anchoring. It computes the ideal chain length based on various crucial factors.

Formula of Anchor Chain Length Calculator

The formula used by the Anchor Chain Length Calculator is:

Chain Length (in meters) = Depth of Water (in meters) + Freeboard (in meters) + Scope Factor * Anchor Height (in meters)

Where:

  • Chain Length is the required length of the anchor chain in meters.
  • Depth of Water refers to the depth of the water where anchoring is planned (in meters).
  • Freeboard is the distance from the water’s surface to the boat’s deck (in meters).
  • Scope Factor represents a safety measure, usually ranging from 5 to 7, accounting for the amount of chain or line to be let out for proper anchoring, adaptable based on preferences and conditions.
  • Anchor Height indicates the boat’s bow height above the waterline (in meters).

Example of Anchor Chain Length Calculator

Suppose a boat with a Depth of Water of 5 meters, Freeboard of 2 meters, Scope Factor of 6, and an Anchor Height of 3 meters. Using the formula:

Chain Length = 5m + 2m + 6 * 3m = 5m + 2m + 18m = 25 meters

Most Common FAQs

Q: What is a suitable Scope Factor?
