The '''Felixstowe F.1''' was a British experimental [[flying boat]] designed and developed by [[Lieutenant Commander]] [[John Cyril Porte]] [[Royal Navy|RN]] at the [[RNAS Felixstowe|naval air station]], [[Felixstowe]] based on the [[Curtiss Model H|Curtiss H-4]] with a new hull.<ref name="orbis" /> Its design led to a range of successful larger flying boats that was assistance in promoting Britain as a leader in this field of aviation.<ref name='Golden'/>
==Development== Before the war Porte worked with [[United States|American]] aircraft designer [[Glenn Curtiss]] on a trans-atlantic flying boat. Due to the start of the [[First World War|Great War]] he returned to England, eventually to command of the [[RNAS Felixstowe|naval air station]] at [[Felixstowe]], Suffolk.<ref name="orbis" /> Porte decided that the original Curtiss flying-boats that the Royal Navy acquired could be improved and a number of modifications to in-service flying-boats were made.<ref name="orbis" /> The modifications had a mixed result so Porte using the experience gained, developed with his Chief Technical Officer [[John Douglas Rennie]],<ref name='Golden'/> a new single-step hull known as the Porte I.<ref name="orbis" />
The Porte I hull used the wings and tail unit of an original H-4 (No.3580) powered by two [[Hispano-Suiza 8]] engines; the new flying boat was designated the Felixstowe F.1.<ref name='Golden'/><ref name="orbis" /> During trials of the F.1 two further steps were added to the hull and a deeper V-shape which greatly improved the performance on takeoff and landing.<ref name='Golden'/><ref name="orbis" /> Porte went on to design a similar hull, the Porte II for the larger [[Curtiss H-12]] flying boat, which became the [[Felixstowe F.2]].<ref name="orbis" /><ref>{{cite journal|last1=Rennie|first1=Major John Douglas|editor1-last=Pritchard|editor1-first=J.
