<p>hi kim,</p>
<p>i installed a raymarine st1000 in my former tiki 26, polynesia, similar to gerald's; in fact i took the idea from him. no bullseye fairlead in my case, and it worked pretty well; never a problem.</p>

<p>Robert,</p>
<p>Perhaps leverage is the key. My Tiki26 came with a Raymarine ST1000, but I am unclear as to how it was set up or how well it performed, so I've been wrestling with how to reinstall it. From the physical evidence, the best I can figure is that the base of the tiller pilot was mounted on the inboard rail of the port hull about a foot behind the aft beam, and connected with a short "pseudo" tiller that hinged at the aft beam and met the tillerpilot at a right angle.

<p>Perhaps leverage is the key. My Tiki26 came with a Raymarine ST1000, but I am unclear as to how it was set up or how well it performed, so I've been wrestling with how to reinstall it. From the physical evidence, the best I can figure is that the base of the tiller pilot was mounted on the inboard rail of the port hull about a foot behind the aft beam, and connected with a short "pseudo" tiller that hinged at the aft beam and met the tillerpilot at a right angle. It looks like this was attached to the tiller bar where they intersected.</p>
<p>Looking at your setup, I imagine you could increase the tillerpilot's leverage by lengthening the short rod attached to the rudder head, although this would alter the angle to your base mount and proportionally stress the rod. Imagine trying to steer with your own hand using that rod, versus at the tiller bar. That would give you a sense of the torque that the tillerpilot has to deal with. Given the "hysteresis" built into the tillerpilot's programming, I would assume there is a sweet spot in the torque needed: too much torque demand (i.e. too short of a lever arm) and it would need to work too hard and potentially understeer, and too little torque demand might cause it to oversteer.</p>
<p>This may not be very helpful, as I don't have the Raymarine specifications at hand, but the goal would be to get as close to them as possible. Would two rudders mean one would halve the necessary lever arm to arrive at the correct torque at the rudder pivot? Or would the turning moment of two hulls cancel that out? Seems like a question for a Raymarine engineer, but one that could ultimately be solved with a little math.</p>

<p>Robert,</p>
<p>That's very useful - thank you. I've been wondering how to do this on my Tiki 21 and will definitely use your system when the budget allows. I had a look around online, and one approach could be to use stainless aftermarket automotive tie-rod arms and universals.</p>

Yes, ineffect the rod coming of the tiller acts as the tiller and we are using an overlong push rod. The problems are around minimising movement in the linkage and flex on the rods plus the inherent problem of the weight of the tillers and the angle of the rudder attachement to the hull as discussed in the thread above.

<p>Does the tiller pilot work OK in the fore-aft position, given that the Raymarine instructions say to mount it athwartships?</p>

<p>Below is a pictur4e of the prototype. The rod coming off the tiller was bending so I am going to replace it with stainless steel tubing, otherwise it worked pretty well. The swivel joint is produced by RWO for tiller extensions. I need to come up with a better way of connecting the tillerpilot to the push rod, currently it slots inside the tube and a pin is pushed through to hold it but this is a bit cumbersome.
