I've had my rudders apart and now my boat is slow.... :(
Rudder rake and mast rake have been set -- now just a little helm to weather.

1) ARE there port and starboard rudders?

2) What is the best way to align the rudders? My method:

Measure 15 inches down from the top of the rudder, and make a mark ( I use a grease pencil).
Draw marks, straight across from the 15 in mark on the leading edge and on the trailing edge of both rudders.
Measure rudder to rudder the leading edge seam at the mark , measure rudder to rudder the trailing edge seam at the mark and compare. Adjust at tiller if needed.
Should the rudders be towed-in with the trailing seam bigger than the leading edge?
Should the rudders be towed-out with the trailing seam less than the leading edge measurement?
Or should the meaurement be the same?

Port and Starboard rudders? No... Assemblies? YES!

The upper rudder castings are not symetrical on Hobie USA boats. They should bow the tiller arms towards the centerline of the boat. If they were reversed, they would cause the rudders trailing edges to be far outside the leading edges. This would mean you have two rudders dragging (slightly) sideways through the water.

Look at the rudder from the rear of the boat. Line up the blade with the hull and look at the tiller arm. The arm should be angled towards the center of the boat. Leave that rudder in-line with the hull and then look at the opposite sides rudder alignment. The blades should (generally) line up.

The true test of alignment requires measuring the difference between leading and trailing edges. On a 16, the leading edge should be about 1/8 - 1/4 inches closer together (Toe In).

MMiller,

Thanks for the reply... Well, I've been measuring the rudders again.. And Again, And Again. The measurements were changing :x .. Now, I started to look at everything. Rudders, castings, gudgeons ( a little sloppy), tiller tubes, tiller adjusters and tiller connections. To my surprize one tiller connection was loose. Not enough to wable, but loose enough to make a new location when stressed.... I'll check everything out on my sunday sail.... :D

My tiller connections are a "ball & socket" and came with the boat when I bought it last year. I can't seem to find a replacement. Where did they come from?

Maybe Santa will treat me with new tiller connections like the Miracle 20 style this winter...

Harry

Those are likely Kisseme (sp?) parts. I think they are long gone. The best kit is the 1953 tiller connector kit. Works great and has been the standard on most of our cats for many years. Hobie Parts catalog page 35 upper left corner.

Thanks Matt.

I've just made another order to my Hobie dealer and I'll have to wait to order these the next time I order...


Probably, when I do the winter rebuild.


Thanks again
Harry
