Difference between a conventional (441) and an axle (442)
The axle is a form of the bow of a ship, characterized by a fully vertical pole and a relatively high and narrow forehead, a bow in the shape of an ax. The ship intersects the water as it were and stays with the bow in the water. As a result, the vessel is less sensitive to wave movements. Because the bow does not get out of the water, the ship does not suffer from wicking. This effect is achieved because the narrow hull of the fork has less buoyancy and thus slows down the movement. A small disadvantage of this hull shape is that the ship is by her greater length, less viable. This can possibly be captured by applying a larger stirrer. Another disadvantage is that the water resistance is slightly larger due to the larger hull surface.
The vertical pole is not unique in itself, which also occurred in the steam era. The innovation is in the narrowing of the bow, an idea that was developed by Lex Keuning of the Faculty of Mechanical Engineering, Maritime Engineering & amp; Technical Materials Sciences, 3mE (Mechanical, Maritime and Materials Engineering) of Delft University of Technology, advisor of the Damen Shipyards Group in Gorinchem, together with Marin (Maritime Research Institute Netherlands) in Wageningen, the Royal Navy in The Hague, the Royal Schelde Group in Vlissingen and the United States Coast Guard. It was designed Fast Crew Supplier 3507 and it was first performed at the Sea Ax, in aluminum.
