Navigation General · Tidal Currents
To find the velocity of a tidal current at an intermediate time between slack and maximum, the navigator uses the Tidal Current Tables with:
- ATable 3 (velocity of current at any time)✓ Correct
- BThe Light List
- CThe deviation card
- DA star finder
Explanation
Table 3 of the Tidal Current Tables gives the factor to apply between slack and maximum to estimate the current velocity at any intermediate time, just as the Tide Tables interpolate tidal height.
