<div style="text-align: justify;"><span style="color:#00008B">In August, 1876 the Fenians agreed to finance the construction of a prototype. By this time Holland had been influenced by the industrial revolution and the design that he had built for the Fenian demonstrations was considerably more advanced. Now officially dubbed the "Holland I" by its inventor, this boat was 14 feet long and 3 feet wide and was designed for a one man crew. It was built in a local iron works in Paterson, [http://vintagemachinery.org/mfgindex/detail.aspx?id=860 '''Todd & Rafferty's'''], with some elements manufactured at the Albany City Iron Works in New York City. Iron hulled and riveted together, manufacturing was kept simple by making the cross-section of the boat square, allowing the simpler cutting and bending of the iron plates without having to roll them into a circular shape. It was no longer human powered. A 15 hp, two cylinder [https://en.wikipedia.org/wiki/Brayton_cycle '''Brayton Ready Motor'''] was installed just forward of the operator station, turning a two blade propeller. One set of diving planes was sited amidships, where they could be easily worked by the single operator. A small cylindrical conning tower with a single forward viewing deadlight porthole was sited center topside. The operator's head would be up in the conning tower while seated below it and aft of the engine. | |||

The early years
On a cold and windy February 24, 1841, John Holland Jr. was born to parents John Sr. and Mary Scanlan Holland in a small coastguard cottage on Castle Street. He was the 2nd of what was to be four siblings, all boys. John Sr. eked out a modest living as a member of the Royal Coastguard Service, and his father's service instilled in John an interest in the sea. County Clare was traditionally Irish, with English spoken only as an aside.
In fact, John did not speak any English until he attended the St. Macreehy's National School just down the street from the house in Liscannor. John proved to be a capable student, but struggled with serious health issues, including poor eyesight. His family survived the Great Famine in Ireland relatively intact only because his father's employment gave them a relatively clean and well maintained house. John witnessed the depredations of the Great Famine firsthand, and the British government's lack of response instilled in him a deeply seated animosity towards the British.
John took to his studies with vigor and by 1853 his family moved to Limerick with John attending the Christian Brothers School there. By age 17 he joined the brotherhood and was given the Christian name Philip, which he retained for the rest of his life. He was soon accepted as a teacher. During this period he fell under the influence of Brother James Dominic Burke, a renowned man of science. John took to the science studies with gusto, displaying a tremendous mechanical aptitude. Brother Burke was conducting experiments in underwater propulsion using electricity and the firing of torpedoes against ships in a model basin. These activities struck a spark in John, and he began his lifelong fascination with submarines.

The Brayton engine was the only means of propulsion. There was no battery or electric motor for submerged propulsion. Compressed air tanks fore and aft supplied air for the engine, breathing, and blowing ballast tanks. Exhaust from the engine was vented overboard. Using less air than a modern lawnmower gasoline engine, running the Brayton engine while submerged was at least practical, if not incredibly dangerous.
