- how to measure wind effects and prepare ship specific diagrams to estimate required drift angles and also rudder angles for wind balance
- to be applied for voyage planning, considering expected operational conditions, specifically for preparing manoeuvring plans for Port arrival and departure planning!
- analysing theses data a simple formula could be derived to calculate the drift angle ß depending on absolute wind speed VA, encounter angle aA and ship speed Vs to:
ß= arctan (CD*(VA +Vs*cos aA)*sin aA)/Vs)
And all this is demonstrated by means of the unique SAMMON Planning software based on Fast Time Simulation of ship manoeuvres...
Enjoy, share and give some thumbs up, if you are satisfied with the movie - and my haircut!
