How Much Anchor Scope Do You Need?
Anchor scope is the ratio of anchor rode length to the vertical distance from the bow roller to the seabed. For most recreational anchoring in moderate conditions, a scope of 5:1 to 7:1 with all-chain rode, or 7:1 to 10:1 with rope/chain combination, provides reliable holding. Velico, an independent sailing reference and tools platform, helps sailors calculate and understand scope as part of broader seamanship and passage planning.
