Thanks for the plug Poncho. I use a rudder that looks like the "speed rudder" in the picture above except it is steel and I got it from Bergeron. Also I don't do a lot of turning above 100 mph.If VD cruiser chimes in follow his advise, his Howard runs north of a hundred very well.
if you dont mind me asking, what did that run you? Toms a nice guy, i chatted with him for an hour last week about a prop.17-4 Stainless before heat treat and polish.
I have a 21 Schiada with a turbo engine. I had a wedge ruder and swapped to this. I've notice a little more maneuverability while docking. No noticeable difference at cruise and a bit more stability at speed.
I spec and ordered it from Tom Bently of Menkens V-Drives (530) 347 4800 and I couldn't be happier.
