For others who may encounter the steering limiter problem or the knot catching issue, this is what I sent dealers last week. We discovered that shortening the up control line can clear the knot issue.

Tandem Island Steering
The steering on a Tandem Island may be restricted or conflict with other control lines within the hull.
Hint: All internal hull functions can be more easily understood or diagnosed by using a video camera lowered into the hull to inspect the functions. The best is to use something such as iPhone FaceTime between two phones or to an iPad. You can move the camera around while viewing on the other device.
• One issue is related to a limiter line used to keep the steering handles from over rotating. This line is at the rear control. The limiter line is attached to the control arm and runs directly across to the opposite side where it is tied off. This line could be too tight and restrict full steering. Knots are tied in the line to tighten it and it is possible that it was made to short with too many knots.
o If you have this issue, look inside the hatch near the rear seat and rear steering control. The limiter line is just aft of the hatch and within easy reach. You would need to detach this line from the steering control arm and untie a number of knots in the limiter line to make it a little longer. It seems that the limiter is not critical to steering function, so some users have simply removed it.
• The other issue is related to the rudder up control line. This line, if too long, allows a turning block and associated lines and knots to conflict with the steering line. This occurs at the aft steering control handle area.
o If you have this issue, you can shorten the up control line a few inches. Lower the rudder and lock it down with the down control line. While looking inside the rear seat hatch, feeling or using a video camera inside the hull, pull on the up control line until the turning block hardware clears away from the aft control line conflict area. Mark the up line where you want to adjust the up handle location to. Pull the line further and clamp off to hold. Pop the cap off of the handle. Pull the knot and line through the handle until at the desired location. Tie a new knot to hold. Test all rudder function before cutting off the excess line and replacing the cap.
