I'm not to fond of drilling holes in the boat so what I'm thinking is to epoxy an aluminum plate on top of the mast head. Then add a block or two at the end of the plate for the halyard. Of course the paint of the top of the mast head would be removed, metal roughed up then JB Weld mixed and applied. Then paint it.



Is this a good plan? Maybe I'm overly concerned about chaffing and this modification is not needed? The boat does have two jib halyards available.

I think you over estimate the strength of JB Weld! That is absolutely the wrong application for that stuff. The loads on a spinnaker halyard can be pretty high. If the epoxies area proves too weak you will have a mess on your hands.

Why are you afraid to bolt anything to your mast? Bolting a block is not going to compromise the strength of the mast at all, but will give you a spin halyard you can have confidence in.

If you are not confident drilling and tapping your mast, perhaps you should enlist your local rigger to help.
