Chart work Flashcards
1
Q
What are the Leeway rules?
A
CTS - Counteract leeway
Everything else - allow leeway
2
Q
How do you get minutes to degrees on the calculator?
A
Minutes / 60 and then press degree button
3
Q
How to plot tide experienced?
A
- Do the maths in question
- Plot your initial position
- Lay off W/T
- Plot your second fix
- From then end of W/T to second fix is your tidal vector
- plot G/T
4
Q
How to plot running fix?
A
- Do the maths in question
- Plot single line of position
- Choose a safe and realistic EP
- Lay off W/T and tidal vector to get a second EP
- Transfer first line of position onto second EP
- Lay off second line of position
- Your fix is where the two lines of position meet
- EP to EP represents your direction and length of G/T
- Transfer your “G/T” to your fix to get real G/T
5
Q
How to plot EP?
A
- Do the maths in question
- Plot a position
- Lay off W/T
- Lay off tidal vector from end of W/T
- End of tidal vector is your EP
6
Q
Course to steer? (No Time Given)
A
- Do the maths in question
- Lay off G/T
- Lay off tidal vector from initial fix
- From tidal vectors end, arc (distance according to time interval) on G/T, this is an EP
- End of tidal vector to arc is your W/T
7
Q
Course to steer? (Time Given)
A
- Plot position (start & finish)
- Lay off G/T
- Lay off tidal vector (same time interval)
- From the end of tidal vector to G/T is your W/T
