: . . . I'm considering building a small"form" in the bow to retain the
: dooky and then boring a hole in the center of the deck to inject the dooky
: and anchor the toggle rope. I'm thinking of making the rope part of the
: pouring process. This would provide an anchor and seal. maybe a knot in
: the buried portion of the rope.

Don't anchor the rope in your epoxy. You'll regret in in a few years.

1.) If the rope cannot move then all the wear and tear will happen at the point where the rope meets the hull. A freely moving loop will wear more evenly. Rope for a toggle-type handle may need replacing a bit more frequently.
2.) The rope will wick water into the "sealed" area and loosen its bond with the epoxy. Thanks to the trapped water, the rope will rot and weaken just inside the hull. It becomes a messy area in a very visible part of the boat.
3.) Even with the best care and cleanliness you will want to replace that rope every year or two, particularly if you use it as a bow tie down, or for attaching your safety ropes when tying your boat onto a rack for transporting.
4.) When replacement time eventually comes you'll have to drill out the old rope. That could be a sloppy job. The drill bit will probably shift around during the process, so you'll have an irregular hole. You'll probably want to fill it and redrill it.

Best move is to embed a tube (plastic or copper) through which you can later insert your rope--and then tie a decorative knot in the rope, or attach a toggle to it.

For security reasons you may want to either make the tube large enough to take your rope and a steel cable, or make it so you can remove the rope to insert a steel cable. A locked steel cable passing through the boat will deter casual thieves from making off with your boat. Rope is far too easy to cut.
