If you have an exceptionally heavy boat or are anchoring in exceptional conditions (typically greater than gale force winds) you may consider going up one size of anchor or larger. This is referred to as the scope, in this case 8:1. If your boat is heavier than typical boats of that length, or presents more windage, you.
However, smaller inshore boats like skiffs and bay boats may want to get a heavier anchor (like a sea claw) to avoid having to use any chain. Marinenow folding square anchor choose 13, 19, or 25 lb (19 lb) features. When choosing the right size boat anchor, it is recommended to select it based on the 30 mph wind rating if it will be used as your primary front anchor. If your engine fails and you are drifting toward a lee shore, having a properly sized anchor ready could save your boat.
