Grahame-White Type XIII
The Grahame-White Type XIII was a racing seaplane built to compete in the Daily Mails 1914 Circuit of Britain air race, to be flown by company founder Claude Grahame-White. It was a conventional single-bay biplane with staggered wings of equal span braced by N-struts. The forward fuselage featured a highly streamlined aluminium engine cowling, with the rest of the construction being wood and fabric. The landing gear consisted of twin pontoons, with a small third pontoon carried beneath the tail.
