Various aspects of the flying boat eased aspects of its operation; it was relatively easy to dismantle for ground transport; the wings comprised three detachable sections while each of the hulls could be entirely detached from the centre section along with the tail unit.

The engine nacelle was inclined, placing the line of thrust from the engines at roughly eight degrees off from the horizontal, this exerting a constant but slight upwards push throughout flight. A key reason for this arrangement was to direct the generated

The twin hulls of the flying boat were spaced roughly 13 feet apart, ran for just over half of the total length of the flying boat, and had a single-step V-shaped bottom. They were constructed in a manner that permitted the internal space to be configured into a series of cabins, accommodating a
