A. A keelboat is a sailboat with a keel- usually a long, thin underwater “fin” that serves two purposes. First, it is usually ballasted with lead or iron to help keep the boat upright and add stability. The second function is to reduce leeway (sideways movement) through the water. In other words, the keel adds “lift” which allows the boat to sail upwind.
