For the sail head connection on the flying drifter, I installed a Racelite Mast Hound available at Duckworks. The small size, I think, but do measure to be sure.http://www.duckworksbbs.com/hardware/rigging/rl325/index.htm
I don't have close up pics, but I believe I mounted the hound just barely above the upper shroud bolts through the mast, then put a smallish swivel block on the end of the hound, with dedicated halyard. Now since the CP19 is a masthead rig it allowed for this mounting location. The location would be considerably lower on the Eclipse, I think...
You do have to be careful to ensure there is no interference with the furler halyard, swivel and rolled up sail in that area. Mine fits well but I seem to recall hemming and hawing over this quite a bit before drilling the hole and ordering the sail (custom since the luff is unique). I actually run the main and drifter halyards through the port side aft led blocks and the jib halyard I cleat to the mast. That way you don't have halyards crossing the furler and have control over the drifter from the cockpit.
You could also consider just getting a nice size genoa instead with lightweight cloth, or even nylon.It might point a little better? I went with the drifter because I didn't want to take down the jib/genoa on the furler. Too much hassle and if the wind picks back up again it's a whole lot easier to douse the flying sail than removing it from the furler and re-installing a jib.
And yes, I can go dual headsail wing on wing if I want to. I did try it once just for fun but generally just let the main fill the headsails instead and tie on a preventer to the boom to keep the main from creating an accidental gybe.
Capt Nemo is right...nylon is the right way to go when considering a light air sail.
Also, don't underestimate your technique as you can squeak out more speed without these sails. Maybe not much, but sometimes that's enough.
Loosen halyards, let the foots breathe, don't pinch too tight, watch rudder (brake) angle. Loose footed fully battened mains are real nice in light air too.
