Calcule la sonda bajo la quilla en el momento del atraque:We enter Barbate at the time of the second low water of the day with a maximum draught of 1.66 m and berth at a charted sounding of 2.20 m, the Tide Tables giving a second low water height of 0.76 m. Calculate the water under the keel at the moment of berthing:
Show the answer
Correct answer: b) 1.30 m
Why it is correct
At low water there is no correction: 2.20 + 0.76 − 1.66 = 1.30 m.
Why the others are not
- a) The result is different.
- c) The result is different.
- d) The result is different.
How to work it out in the exam
- Water under the keel = charted sounding + height of tide − draught.
- The height of tide is the low water plus the additive correction from the Anuario.
