Tim, when I anchored out on my M-15, my boat would swing to and fro, too. So, I bought an anchor riding sail from Sail-Rite, rig it when I anchor for an overnight, and have found the to and from motion is greatly, greatly reduced, now.
I have no sewing skills, so I paid Sail-Rite to assemble the kit for me. http://www.sailrite.com/anchor-riding-sail-kit Sincerely, John M-15, 624, Bella _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats
