Tom, I think your suggestion of removing some portion of the toe rail and using at least one pre-existing hole on each side is the way I'm going to go. Do you, or anyone, know why the toe rails are staggered at the bow? From the headstay chainplate to the first hole on the port side is 5 1/4" and on starboard it's 3 1/2". The toe rail is not even at the stern either, but to a lesser degree. It's hard to believe that such a nicely put together boat would have the toe rails put on in a haphazard way. What size chock did you use and do you have a preference between a straight bow chock and a skene chock? Thanks, Rick Langer M15 #337 Rick, I removed a few inches of toe rail on my M15 to accommodate bow chocks. I liked the idea of reusing one existing hole (the foreward-most toe rail attaching point), and only having to drill one new one on each side. This approach had the added advantage in my mind of situating the chock over the deak/hull seam, which is a very strong point on the deck. I personally hate the idea of drilling through the balsacore deck of the M15--it's an invitation to damage the integrity of the sandwiched material. The chocks are slightly uneven side to side (because the bolts attaching the toe rails are located different side to side), but it's no big deal to me, and it looks good. t Tom Smith and Jane Van Winkle M15--345 Chukar M17--064 Unnamed
