Pender was recorded as the second master of the admiralty survey vessel, HMS Plumper, in 1857 when he arrived at Esquimalt.[1] He was promoted as the ship's master in 1860. He was, however, transferred to HMS Hecate a year later after the Plumper was deemed too small and unsuitable for the coast's waters.[1][2] When the British government commissioned the Hudson Bay Company to continue the hydraulic survey of the coast, he was given command of the company's Beaver.[1] He replaced Captain George Henry Richards, who was recalled to Britain after he was appointed as the Hydrographer of the Royal Navy.[3]
