2 400 The length of a knot for a thirty second glass is 50.66 feet = 50 feet 8 inches nearly

This log is hove from the lee quarter and as soon as the red rag is on the taffrail, the glass is turned and the speed of the ship will be the number of knots run over the rail while the sand in the glass runs down.

The examiner does not as a rule require the applicant to perform this calculation. The answer to the question as given on page 29, is all that is necessary.
