The model represents a study for a boat that can ram enemy vessels. The hull of the ramming boat is very strong, with no sails and fitted with a metal ram just under the water level. The rowers are protected by a mobile shield. The hidden artillery is used to take the enemy vessel by surprise. The most significant characteristic of the boat is its high speed and its consequent collision strength. High speeds are reached thanks to the shape of the hull, which has a 12 to 1 ratio between length and width.
