[2] The hull was internally divided into three large compartments that were separated by a pair of water-tight bulkheads, one of which was outfitted with a door that would instantaneously close.

[2] The manufacturer claimed that these water-tight compartments in the full, in conjunction with those in the wing, meant that the flying boat was practically unsinkable.

The central compartment contained the flying boat's sizable and relatively luxurious cabin that could accommodate as many as 15 passengers along with an lavatory.

Considerable attention were put into noise dampening measures as part of wider efforts to maximise passenger comfort levels.

Additionally, rubber bands were present in between the protective fittings of the spars and the upper and lower edges of the fuel tanks that rested against them.

They were also positioned relatively close to the hull, which made it easier to simultaneously alight upon them; they were connected to the central section of wing.

[5] The vertical empennage comprised a fin and a pair of shield-shaped auxiliary surfaces that could turn about their axes of symmetry during flight and functioned as correctors.

[15] All the flight controls were rigid and mounted on ball bearings; a maximum of two supports were present between any two joints in order to obtain straight shaft lines even in the event of the framework sustaining deformation.
