We have no trouble anchoring from our bow, but occasionally we have had to put out a stern anchor also due to a strong current or because our neighbors were using such a setup. The problem with the stern anchor is that if we rotate even a little bit, the rode puts pressure on the rudders. A couple of times we've actually noticed that the rudders were perpendicular to the boat and once the extreme angle broke off the tiller bar sensor on the auto pilot.
Does anyone have a setup that prevents this? We've tried tying the rode to a cleat on the stern and letting the line run to the outside and another time to the inside. We've also had it run straight back from the winch that is in the middle of the back beam (not the stern tube which doesn't seem strong enough). In all cases, the line moved and pushed against the rudders or traveled under the boat and pulled the rudder to extreme angles.
We are trying to avoid putting out a stern anchor at all costs, but sometimes safety demands it. In those cases I end up staying awake all night just waiting for the sound of the rudder snapping in two.
Thanks for any help!
The other thing you can do if you have a netting beam right at the stern is put fairleads on it to pass the anchor rode through. I have used this sort of set up when towing dinghies and it seemed to do the trick, especially when there are 2 fairleads and a bridle (as Marty described) rather than one in the middle.
Another trick if the problem is yawing is to stream a drogue or bucket astern.
