Re: C&C 26 Spinnaker halyard
So you had an internal halyard and it's run out?
You'll need a good bosuns' chair, small twine/string and about 6 inches of bicycle chain. Get yourself or someone else up to the masthead in the chair, tie the string to the bicycle chain piece and feed it over the halyard block and into the mast slot.. Have someone at the bottom exit slot with a good flashlight and a wire hook of some sort. When the chain piece gets in the area of the slot he'll hear it and can snag the string.. pull it through, attache the new halyard securely and pull that through.. voila there you go.
The spinn halyard probably did not have anything to do with the masthead assembly other than the crane for the block.. .. it should be out on the crane and then re-enter the mast a foot of so down from the top, so pulling the cap wouldn't help much.
