Pythagoras theorem and similar shapes

Swimmer A and boat B, shown in the diagram, are 80 m apart, and boat B is 1200m from the lighthouse C. The height of the boat is 12m and the swimmer can just see the top of the lighthouse at the top of the boat's mast when his head lies at sea level. What is the height of the lighthouse?
