Hull Thickness on Modern Ships

Victor

On some modern ships, you can see where the frames are behind the hull, suggesting the hull steel is relatively thin.

Does anyone know what thicknesses are typical?

I dont know about ships,in smaller boats different areas have different thickness depending on the strenght thought needed.In smaller vessels there is a tendancy in recent years to go lighter steel as it makes them lighter on fuel leading to a "greener" vessel.Longterm i would not be convinced this will make economic sense as surely the life of the hull is shortened considerably.

Stovepipe

try half an inch and probably no thicker than three quarters of an inch. reinforced only where it needs to be.

LiamoSail

12mm is pretty standard, thicker (14 to 20mm) in way of anchor housing, keel, stem and waterline strakes. Ships of special construction may be thicker. Eg ice belt on Ice Class ship.
