Emerald was a steam yacht that was launched in Glasgow in 1902 for the shipbuilder, shipowner, and politician Sir Christopher Furness.

Alexander Stephen and Sons in Linthouse, Glasgow built Emerald as yard number 397.

[3] By May 1909, J. Samuel White of Cowes had replaced the steam turbine on her middle propeller shaft with a three-cylinder triple-expansion engine.

Lord Inverclyde acquired Emerald, renamed her Beryl, and registered her in Glasgow.

The Glasgow Herald reported: "Fire broke out in the after peak, spreading so quickly through the inflammable interior that before any substantial help could be brought to the scene, the vessel was a mass of flames, and practically beyond hope of saving."
