Quick Summary

Types of keels
Types of keels

A fin keel is a component used in shipbuilding, particularly for shallow boats like yachts. It is a long, narrow plate, often made of metal, that is attached to the main keel and extends downward from the hull. The primary purpose of a fin keel is to provide lateral resistance, which helps prevent the boat from sliding sideways. Many fin keels are also supplemented with a bulb, typically made of lead, to enhance stability. In essence, a fin keel improves a boat's ability to sail effectively and maintain stability, especially in shallower waters.12
