    This rudder setup drove Dan Newland and me crazy when we first saw it. The designer (Clint Chase) had a preferred construction.

    It is on the list of changes.

    What do you see that makes this less than ideal?

    The curved rod, to match the curve of the ...hm... "aft stemhead"??? Not gonna work unless the pintles are really thin or really loose. They're going to bind.

    Alan is right about the pivot rod. The gudgeons and pintles are not on the same axis, the rudder does not turn freely. The slop in the rod allows about 30-40 degrees of movement to each side. Then, the rudder binds up and stops. Also, the rudder portion of the attachment is captive within the hull portion. The lower portion (kick-up part) of the rudder is removed with a wing nut. To remove the upper portion of the rudder, a hammer and drift is needed to drive the curved rod out of the system.

    The designer has plans to get the pivot points in line by recessing the upper and shimming put the lower. Short pins are designed to make it easy to install and remove assembly. To enhance the kick-up feature, a shock cord is attached to the front of the lower portion of the rudder to pull it down, but allow it to kick up if an object is hit. A line and cleat allows the lower portion to be raised manually.

    Fun sailing is the result of well thought and executed details.
