The English Electric M.3 Ayr was a British three-seat coastal patrol flying boat designed and built by the English Electric Company. The aircraft refused to become airborne and the project was abandoned. DevelopmentWhile the company were working on the Kingston they decided to experiment with a design for a small flying boat. The aircraft was a single-engined biplane flying-boat named the Ayr and was built in 1924. The hull was designed by Linton Hope who had designed the Kingston hulls. The lower wing was mounted low on the hull where the root was fully submerged while on the water, and inclined with considerable dihedral. It was designed to both provide lateral stability while on the water, and to carry bombs. During trials the aircraft rolled to the right and was unable to become airborne.
