Who invented the hydroplane?

Answer 1

Early designs of the 1920s were often designed by amateurs based on the designs of naval motorboats designed by the professional designers working in the boatyards. The amateurs employed the lightest materials available to them at the time, which were often glued timber boarding or plywood on the floor, 4-millimetre (0.16 in) plywood topsides, and varnished canvas decks. Most were about 4 metres (13 ft) long and stepped hulls were employed with a 75-millimetre (3.0 in) step to induce air under the hull, to enable the boat to float on air bubbles. The concept of 'planing' was not fully understood. Thus, hulls were flat bottomed with an upward curve at the bow and the step 2/3 of the way aft. The sheer weight of a 100hp. engine was enough to keep the bow from digging in. In Ireland the sport was managed by the Motor Yacht Club of Ireland who had a base at the Lough Ree Yacht Club near Athlone.

I believe in what this person said but because i had to research about inventions, i found that the hydroplane was invented by a person (not sure if boy or girl since i saw no picture)Bell, Alexander Graham
