Hi Charlie. No drilling is necessary. I removed the most forward bolts from the stern cleats and replaced them with SS eye bolts On the clutch cord I fastened a STRONG 8 in length of bungee at one end and at each end attached a SS snap fastener. When sailing you have excellent response from the clutch. To secure a dock line to either cleat, you just unsnap the cord end at the appropriate cleat,attach the dock line and snap the clutch line back in place. Reverse the procedure when leaving the dock . No fuss, no muss. Pls destroy the unintelligible e mail sent earlier in error. Best of luck RTH. -----Original Message----- From: Charlie Fortner Sent: Tuesday, April 15, 2014 8:42 AM To: montgomery_boats@mailman.xmission.com Subject: M_Boats: TillerClutch control line on an M15? I sure do like my newly installed TillerClutch. Beats the old bungee by miles. However, tying the control line to the stern cleats is less than ideal for several reasons. I'm thinking of installing cam cleats on the transom to hold the line. But before I go drill holes I'd like to know what others have done. Charlie M-15 #411
