Can any one who’s has a 27.3 with an Assymetric send some pictures of the halyard set up ( above gib I assume), the position of top pulley and if run through mast or externally? I have in mast reefing so reticent to cut into it. Thank you

The spinnaker halyard will always need to be ahead and above the jib halyards. No matter the boat. Because the sail rides ahead and outside the upwind sails. If it's a fractional rig, where the forestay attaches to the mast somewhere below the tippy top, you can mount a good quality rotating block directly to the mast. With a masthead rig, where the forestay will attach at the very top, often mirrored to backstay, you might need an extension(crane) on the masthead fitting to get the spinnaker halyard block out ahead of the forestay.... especially with a roller furling headsail or a spinnaker dousing sock.
I've always preferred an external spin halyard. Easier for foredeck crew to set and "jump" the halyard. Less chance to affect preexisting internal mast rigging and wiring.. Finally, it's just easier to set up.. i.e no cutting. keep everything at the mast,

Thank you. I’m a little nervous as the rig is a B&R with no backstay. There is not a lot of space between the top of the forestay and the radar reflector and additionally I’ve seen comments to say the spinni shouldn’t be above where the shrouds run into the mast ….. which is the height of the forestay on the mast. ( Please see pictures.). Hence query, as I understand that it is OK to put Assymetrics on these boats.

Also, as a thought, would a single rivet into the mast be sufficient? Or do I need a more substantial mast connection?
