HMS Pelorus displaced 2,135 tons and had a top speed of 20kn. She had reciprocating triple expansion engines and Normand water-tube boilers which could give for limited periods of time with forced draught, and under natural draught. It carried a crew complement of 224 men and it was armed with eight QF 4 inch (102 mm) (25 pounder) guns, eight QF 3 pounder (47-mm) guns, three machine guns, and two 18-inch (450-mm) torpedo tubes.
Pelorus served in the Channel Fleet under Captain Henry Charles Bertram Hulbert, when in February 1900 she joined the Eastern division of the fleet.[2] In 1901, the ship was stationed at Gibraltar under the command of Commander Ernest Troubridge. The following year she paid off at Devonport, had her boilers repaired,[3] and in August was towed to Clydebank to be refitted by Messrs J. Brown and Co. in Glasgow.[4]
In 1906, the ship was assigned to the Cape of Good Hope Station under the command of Commander James C. Tancred. In 1908 the captain was Arthur W Craig.
