New weather forecasts
When the hull is clean and newly painted the hull roughness parameter should be 0 and the
ship performing according to the curves.
With increase of roughness the performances of the ship decline and the consumption
increases. The navigator controls the effect of the roughness by entering a coefficient in hull
roughness (Around 5% per year for example).
