balance the weight of the person taking the measurement is a good idea. This is also true of any
temporary list the vessel is experiencing. On small survey vessels, a person leaning over the side, to
take the draft measurement, can induce upwards, or exceeding a 10cm error in depth readings
during survey operation.
On some vessels it is advisable to take draft readings during the survey or immediately after
completion of the survey, as the draft will change that much.
All offset information should be recorded in the daily survey log and the vessel’s permanent survey
record.
