Building a Wharram-designed Narai MK IV
Wilson, close the gap between hull and rudder, you have some options to do this...
Rogerio, it's not really installed -- just hung there temporarily.What kinds of options are you thinking of?
I noticed a lot of turbulence behind our new lashed rudders. You can't close the gap more than the diameter of the rope, and you can't provide a fixed fairing like with a pintle/gudgeon hinge, since the rudder isn't pivoting from a fixed axis.My idea was to attach a flexible rubber strip on each side of the hull and having it extend a few inches past the lashing on the rudder, so both sides always cover the gap between hull and rudder.But Wharrams are fast enough regardless of a little turbulence back there :)Looking good!
