Re: Bob Perry's take on Wolfenzee's dream boat
You mention the risk of an outboard rudder sucking ir down the low pressure side . How do you feel about the option of a cavitation plate on both sides , just below the surface, such as those used on outboard motors? Regardless of such surface air, the high pressure side is still diverting a huge weight of water , generating a huge side force.
I have never had a problem with such surface air being sucked down, in 38 years of sailing with outboard rudders.
