"His policy was both wise and strong. While not encouraging transoceanic adventure in the face of predominant Spanish power, he made possible the future liberation of his country's energies by the only means—the foundation of a Royal Navy... It was Henry VIII who built an effective fleet of royal fighting ships, with royal dockyards at Woolwich and Deptford; he also founded the corporation of Trinity House. Henry's maritime policy had a double importance. Not only did he create ships specially manned and commissioned to fight, and to fight in the public service alone, but his architects designed many of these royal ships on an improved model. They were sailing vessels better adapted to the ocean than the rowed galleys of the Mediterranean powers, and better adapted to manoeuvring in battle than the more clumsy ‘round’ ships of the mediaeval type in which the English merchants sailed the sea, and in which the Spaniards crossed the Atlantic. The new type of English warship was three times the length of its beam or more, while the normal ‘round’ ship was only twice the length of its beam. Hitherto sea-battles had consisted of ramming, archery and boarding, very much like the battles of the old Greek and Roman navies. But a new age was at hand. From the port-holes of Henry VIII's fleet protruded the iron mouths of great cannon in a row, ready to give the shattering ‘broadside,’ the operation of war to which, more than to any other, British maritime and colonial power owe their existence. It was Henry VIII himself who had insisted that his naval architects should mount heavy cannon in the body of the ship; they had devised the expedient of piercing apertures in the very hold itself through which the great shot could be discharged."
