**Apparent wind, seems important
combination of true wind and wind from the boat's own movement
think vectors
the two balances each other out
if true increases, apparent increases
if speed increase, apparent decreases
"When the wind blows astern, the boat is driven forward by the force of resistance to the wind. Thus, the bigger the sail area, the bigger the resistance, the faster the boat will move."

Types of waves
Ripples When the wind is light, ripples appear on a smooth water. Once the wind is gone, so are the ripples. If the wind gains on strength, ripples will grow into seas.
Seas These are larger waves when the wind is stronger, and they don't go away when the wind stops. Instead they develop into swells.
Swells Large waves that are not related to the local wind conditions, they move away from their area of origin.
