Sailboat anchor issue: rope lifts shank, flukes can’t dig in, affected by wind direction.

Anchoring Rode and Scope

To hold a sailboat, the anchor must naturally be attached to the vessel. This is accomplished by using “rode,” which is either all chain or a combination of rope (nylon line) and chain. Learn from this interactive animation.
