 A measure of the success of Porte's work is that the Curtiss Aeroplane and Motor Company manufactured the F.5 as the F5L and Aeromarine 75.Acutely aware of the flying boat's limitations, Porte pioneered the use of a small towing lighter with a planing hull to increase their effective range.The lighter was designed to be "trimmed down" with water ballast to enable the flying boat to taxi up on to the deck.
