Wrapping up an earlier thread... We decided to install our series drogue chainplates along the caprail. My initial thought was to place them along the topsides near the transom, but we've got a diesel heater that would interfere. So, our chainplates are installed under the pushpit. They're bolted through the deck joint, so there is lots of "meat". Unfortunately, we couldn't fit a full-length backing plate, so we have a series of individual backing plates on each bolt. There are 5, 3/8", bolts (2 are hidden under the pushpit stanchions) attaching the chainplate - plus the bolts for the cleat and the stanchions. So, a total of 11 fasteners, all with backing plates. I'm pleased with the location, and, aesthetically, they blend in well enough. You don't notice them from a distance because of their orientation.
