A, Frederick Savery was born in 1840 Sheerness Kent, the 1861 census he is in the Royal Navy, by 1881 he is listed only as a seaman in Minster Sheppey Kent. He marries Sarah A E Moon in Minster 19 Aug 1884, on the 1901 and 1911 census they are living in Portsmouth. He dies in Portsmouth in 1913.
There is a F. Savery listed on the HMS Shah medal Roll with clasp 1879. I expect this is the same man.
