What was the weight in tons of the Titanic's main anchor?

Titanic’s main, or centre, anchor weighed about 15.5 tons. It was the largest of the ship’s bow anchors and was carried in a special well on the forecastle deck, directly above the stem.

The enormous Hall-type anchor was manufactured by Noah Hingley and Sons in Netherton, near Dudley, England. Its size made ordinary handling impossible: approximately 20 Clydesdale horses were needed to haul it by wagon to the railway station. Titanic also carried two side anchors, each weighing roughly half as much as the centre anchor.

A powerful crane was installed on the forecastle to raise and lower the centre anchor. The anchor itself was only part of the equipment’s mass; the associated cable and chain added many more tons. The side-anchor cables alone weighed about 96 tons in total.

The wording “15.5 tons” usually refers to British long tons, not modern metric tonnes. The centre anchor was also sometimes reported as about 15.6 long tons depending on rounding. That small difference does not change the accepted quiz answer.
