SELECTING AND DRAWING TRACKSELECTING AND DRAWING TRACK

1. Calculate, mark and shade LDLLDL = DRAUGHT + SAFETY (2m) - HOT

2. Isolated Dangers

3. Effect of early / late arrival

4. Selecting track- Good leading marks- Centre / Stbd side of channel- Charted recommended track- Directions from Sailing Directions- Blind PIs

DISPLACEMENT OF CLEARING DISPLACEMENT OF CLEARING BEARING FROM LDLBEARING FROM LDL

• 90º = l

• 45º = 7/10 l

• 30º = 1/2 l

15º = 1/4l

l

Angle indicated in each case is the maximum inclination to the LDL permissible for that clearing bearing

6. Mark distance to run- to berth, anchorage, ETA- time past key points- virtual ETA

7. Mark “Wheel Over” positions

8. Note Tidal Stream & CTS

9. Draw up Blind plan
