[quote=HULLFLYER]I promise you what I said will take care of the rudder problem (just try it) unless the part is completely worn out. I bought my first P-16 in 1977 and have owned several new P-16 P-18 P-18/2 P-19 and they all have the same rudder system. I have adjusted my own rudders and have helped several others in the past 30 years. The rudder has only 1 pivot point, so if you think about what happens if you screw the cam in or out, you will understand. Also do no overtighten the nut and bolt that hold the springs in place, as they have to be able to move to work properly.
The photo Kinlawk posted is the exact part that I am talking about adjusting, that is why is has threads. To futher help the rudders you need to take all of the slop out of the system. Start by putting spacers between the rudders and the castings then raise the rudder to the up position and tighten the pivot bolt so the rudder stays up, and then back off the nut just until the rudder drops, then make sure that there is no slop where the tiller connector bar joins with the rudder casting arms, and finally make sure that the tiller (hiking stick) connection has no slop. Put the rudders down and measure up 22 inches from the bottom and make a mark on both the leading and trailing edges. Measure the distance between the leading edges and then the trailing edges, adjust until they are the same. Hobies like 1/4 inch toe in but I find that Prindles run best if they have no toe in.
Seriously, I have owned and sailed Prindles over 30 years and have helped many sailors with the exact problem.[/quote]
