Neapolitan galleasses combined galley speed with galleon firepower in a partly successful design

Evidence

The galleass was an attempt to combine the speed of the galley with the fire power and sea-keeping qualities of the galleon. The attempt was not altogether successful, but they were formidable ships. The galleasses of Naples with the Armada mounted fifty guns apiece, some quite large, and were manned by three hundred soldiers and sailors and another three hundred rowers. — Garrett Mattingly, The Defeat of the Spanish Armada, 922
