New Ida Rudder

[K3v1n]

Anyone have this as of yet, it is new.

a new CP19 rudder assembly now available, it is complete, offers the gas strut hold-down and one-line raise lower system. Blade raises 180 degrees
for trailering and mooring. High performance NACA foil sized just for
the CP19, about 10" deeper than the original rudder, helps control
the boat in puffy winds or at higher angles of heel which normally
make the boat round up. Helps pointing as well as docking.

I've only seen pictures when I went to the Ida website.

I do have a question though.

Is the stock rudder really that bad on Compacs?  I recently purchased a CP 23-3 and have yet to sail her.  What should I expect?  Should this be my first purchase?

The new Ida rudder helps with performance but that doesn't mean the stock rudder doesn't work at all. I don't believe the rudder is bad, I'll talk to my friend who has a 23 and get his thoughts or perhaps he'll see this thread, he is on here from time to time.

Roger, very body I know who has tried one loves these rudders.
A blade is not bad. It works. But this is better. Skip.
Many post on this site praise this rudder on any Com-Pac size.
The new Ida rudder looks too expensive for me.  skip.

ooh I like the looks of that rudder.  The Idasailor rudder is on my planned list of upgrades at some point in the next year, may have to save up more boat bucks and get one of these when they release it for the c-16.  Thanks for posting the pics.

Although the stock rudder on the 19 doesn't perform as well as the Ida (which I too plan to buy and retrofit to sooner than later), the stock one is so danged sturdy. I know sturdy doesn't help me point as high, but man, the longer I own my 19 I muse at how dang well-built the thing is! The stock rudder is just a solid blade of steel, or some kind of mid weight metal. And the stock/pintle that holds the thing on/and the transom mount are just beefy as all get out.

I was waxing my 19 the other weekend at the marina (on the trailer) and just stood there for a moment, looking at the transom, loving how solid this little boat looks (and is). The problem with performance with the stock blade is that it doesn't have a lead-in/bevel on the leading edge. It has right angle/corners on all side of the blade...no sloping/beveling at entry or on the aft end.

A little off-topic, but had to share that.

That's cast aluminum bolted to the transom with an aluminum blade in the water.
Just a slab of metal alright.. skip.

The stock rudder does seem like it's indestructible.  That's a big plus in my book.  Does the Ida rudder have any durability issues?  Is it prone to certain problems or failures?

What would you say to rounding the edges on the stock rudder a bit? Not so much pointy but something better than square.

Hey Guys,
I'm still here, a foot and a half of snow, some days the high temp has been zero.  Hard to think about boats.
The Ida Sailor foiled rudder makes sense.  It is a foil much like on a jet's wing.  When it presents to the flow of air or water at an angle it creates a low pressure and high pressure area.  It takes longer for the water to flow around one side vs the other.  So the foil turns by pulling you around and disrupts the flow of water only slightly.
Now take the blade - the stock rudder.  It works by deflecting and uses drag.  So when you turn the boat you are slowing down because the rudder is presenting a huge area to the flow of water.
Stick your hand out the window when you're driving and make a flat rudder, now turn it - it is pushed to the side of least resistance.  The foil rudder is pushed and pulled.  Takes less movement or deflection to create the turn.  Less deflection less drag.  If you had a section of a foil the size of your hand and did the same you would notice more turning power with less deflection.
Would you notice this when sailing? 
At hull speed, you have so much excess power the rudder isn't a big issue.  At less than hull speed you will slow down more with a blade.  At really slow speed you may not notice it either because your sails just aren't getting much power.
If you are racing, then this is a big and noticeable improvement.
Hey, if you have the money, it sure looks pretty.  That plastic is tough and much more slippery in water too.

With the rudder that came with my 19 I thought that a nice razor sharp leading edge would help cut through the weeds that arrive each summer in the 'cut' between Lake Michigan and the bay of Green Bay. These weedy buggers actually reach up and stop my boat. It happens each time I try to make the top-O-hour bridge opening...so let's just cut it! Ouch!

By the way, my sailing buddy managed to go aground in a snow storm and was flipping the outboard motor back and forth and also his IdaSalor rudder on the back of this C-P 19, Wind Rover back and forth. So luck would have it, the two got together and deep gouges were chopped into the rudder. Filled with bondo and all is good. skip
