Use the tangent ratio to solve this problem because in effect you have the outline of a right angle triangle: tan = opp/adj adj = opp/tan adj = 60.50/tan 20.24 degrees The boat is 164.0806104 (or 164)) metres from the base of the cliff.
30 degrees
On approaching waves you should reduce your speed and approach the wave at a 45 degree angle allowing the boat to ease up and over the wave rather than smashing head on. Never travell parallel to the wave as you risk capsizing the craft.

When operating a boat in large waves and high wind, you are advised to reduce your speed and head into the waves at a slight angle.
