crew and passengers was married to the hull, aft of the wings these became separate, so that the
Kittiwake was somewhere between a flying boat and a single float seaplane in appearance. This separation made it straightforward to mount the tail high up and well clear of the water. There was a variable-incidence tailplane with unbalanced elevators and bearing three wire braced fins, the central one carrying a balanced rudder.

The two radial engines were also mounted mid-plane in seven sided nacelles, supported by the innermost duralumin interplane struts and steel strut braced to the fuselage. Their faired fuel tanks sat immediately above them, protruding from the upper wing surface.

This had its own enclosing front and side windows and held seven passengers. Though the forward part of the fuselage containing

Saunders and Saunders-Roe flying boats.

As an amphibian the
Kittiwake needed to have a retractable undercarriage, a most unusual feature at this time. The two main wheels were retracted with a hand crank into boxes within the hull, placed between the first and second step. These boxes had cam-operated doors to preserve the hull surface.
178:
Inevitably, this arrangement led to a very narrow track undercarriage. At the rear of the hull/central float was a combined water rudder/ tailskid. Stabilising floats with planing bottoms were fixed to the lower wing below the outermost interplane struts.

The
Kittiwake was a four bay biplane with high aspect ratio, parallel chord Consuta covered wings without sweep or stagger. The lower one joined the fuselage at the top of the hull, with two pairs of struts to just above the
