[1] The lines of the hull were designed around the desired marine qualities of the flying boat; it proved itself to handle well when subjected to five-foot waves.

While the flying boat's duralumin elements proved fairly durable, its steel fittings were not so long-living, despite the application of a protective baked enamel.

[4] The submerged portion of the fuselage was entire1y covered with either a double or triple boarding of Cuban mahogany, upon which a protective layer of bituminous dope was applied.

The portion above the waterline was covered with birch plywood instead, which had a special filler applied to it to absorb ultraviolet light and thus better preserve the condition of the wood.

General instrumentation included a drift meter, altimeter, inclinometer, and a pair of compasses; some aircraft were outfitted with 12-volt generators to power apparatus such as cameras.

[11] Anchoring was aided by the presence of a two-part hatch in the upper surface of the forward deck; baggage was held within a separate compartment just aft of the rear-most pair of fuel tanks.
