Re: Iowa Class Rudders
Probably to be in the streamlines (direction of flow of the water) at that part of the hull to minimize drag and present a zero angle of incidence to the water (not "turning"). Streamlines typically a bit vary based on velocity. I would think that the placement of the rudders was based up flow past them at a specific speed - most likely the highest, efficient cruising speed (around 15-17 knots).
Does anyone know why the rudders on the Iowa class are toed in 2 degrees (so that back is closer than the front)?
