The Ship's Clock
The storm has passed, but Captain Mercer knows that damaged instruments can be as dangerous as hidden reefs.
The ship's chronometer survived the gale, yet its delicate mechanism received a violent shock. Although it now keeps steady time, it no longer agrees with Greenwich.
Using observations with the sextant, the Captain determines the chronometer is 48 minutes slow. Until the ship reaches a port where it can be properly serviced, every navigation calculation must include this correction.
"A clock need not be perfect," Mercer tells the crew, "provided we know exactly how imperfect it is."

Captain's Log
"The chronometer now runs consistently, though it remains 48 minutes behind Greenwich Mean Time. Every observation must therefore be corrected before it can be trusted."
