Bradford,
If your talking about an outrigger hydro, because of our counter
clockwise prop rotation we always race in a clockwise direction.
These boats are not ment to turn left. As far as the rudder placement,
there are a lot of different thoughts about that and you will see
them mounted center, left or right. The turn "Fin" is a whole different
ball game. These boats are ment to run on 3 points. The trailing edge
or very back of the front sponsons and one blade of the prop. The
hull is out of the water and has no V bottom in the water to keep it
in line. If you try to turn with no turn fin up front the boat will slide
sideways and be out of controll. If you put the fin on the left sponsion
it will flip over in a fast turn to the right. If you put it in the center of
the boat the faster you go in a turn the more it will want to flip. If
you put it out on the right sponson it grabs the water just like
if you had a string tied to it and swung it around in circles. If you had
the string tied to the center line of the the boat and one to the transom
it would swing on it's side. if you tied the front string to the right sponson, it would swing level. I prefer to mount my rudder to the
right side of the transom for the same reason.
We also will bend the bottom of our turn fins to the left at the water line to give it even more grip.
Hope the clears things up. :
Anyway, welcome to the forum.
