What are the typical sailboat speeds that can be achieved in different wind conditions?

Sailboat speeds can vary depending on wind conditions. In light winds of 5-10 knots, sailboats can typically reach speeds of 2-5 knots. In moderate winds of 10-20 knots, speeds of 5-10 knots are common. In strong winds of 20 knots, sailboats can reach speeds of 10 knots, with some high-performance boats reaching speeds of 20 knots.
