George was born the son of George Moore (b.1857), a railway porter, and Emily "Emmey" Wareham (b.1859). Although George was born in Enfield in 1880 he appears on the 1881 census residing in Millbrook, Hampshire. George was working at sea by the age of 15. 

George was married in Southampton, late 1904 to Eliza Patterson, née Curson. A widower, she had four children from her previous marriage and would go on to give George four children too.   

On the day of departure from Southampton, George described a boat drill at mid day involving all able seamen. This involved two boats being swung out and lowered. 

On the night of the disaster Moore was off-watch and in bed.  He described a noise like a "cable running out, like a ship dropping anchor. There was not any shock at all." Botswain Alfred Nichols soon came to the seamen's quarters ordering the men to their assigned boat station.  Moore assisted in lowering lifeboats 5 and 7 and in swinging out lifeboat 3. Officer Murdoch then ordered him into lifeboat 3 to assist the women aboard. When no more women were willing or available, Moore admitted to accepting men aboard and judged there to be around 32 people aboard when the boat was lowered.

Moore took the tiller and believed they were about a quarter of a mile from Titanic when it sank. He described how it split in half and he heard two explosions. 

When providing evidence to the US inquiry he was pressed on why he did not return to collect those struggling in the water. He responded that many passengers onboard were strongly against the idea for fear of being swamped and he also explained the cries they heard lasted for only a short time and in the time it would have taken to row back it woul dhave been too late.

Moore continued to work at sea, being called up for military service for World War One and then worked on Oceanic repatriating Canadian forces. By 1920 he was employed by The P&O Company.  On passage returning from India he contracted smallpox so was put ashore at Aden in Yemen. He slept in the open with a only a basic thatched roof. Despite the basic conditions, he managed to recover and set to work in the Southampton docks or working cross channel boats.

George passed away due to a combination of heart and liver problems, aged 63, in 1943. His family fondly recalled him as a hardworking man, who was approachable and made little demands on others despite the hard life he experienced.
