Thomas,
    My M-17 came with one, and i have used it *alot*, mainly when motoring.  I find it works very well.  you have to be conscious of the effect your position has on the attitude of the boat, and hence, its course.  If you shift to port, the boat will slowly veer to starboard and vice versa (because of longer water line on the lower side, i suppose).  So if you get the tiller-tamer set up neutral with you in the center of the boat, you can then leave it for an extended period of time, and steer by your location.
    this has allowed me to make a couple cold, ugly 4 hour motoring passages alot more pleasant by sitting on the edge of the companionway under an umbrella, just peeking over the cabin top to watch for traffic.

Has anyone put a "tiller tamer" on an M17? I'm trying to set mine up for single handing so would like to be able to leave the tiller for a brief period of time.Tom
