Hi Tim, I'd also suggest the TillerClutch. Good quality product, works well, good company, USA made. Have one on our M15 & S17. sal '86 M15 Justus In a message dated 7/25/2012 8:35:43 P.M.

I like the forespar lock box that is used with a forespar tiller extender. One negative right off is that I'm going to have to cut a sizable hole in my beautiful boat. I do like that system however. Then it seems like a lot of you have hardware on the tiller with a line running through it. Friction on the line holds the tiller in place. I would appreciate some feedback. Thanks, Tim Erwin.
