Weight on the mast is 7 more important than weight in the hull therefore try removing all the unnecessary shit from the mast. Strip halyards, change all the rigging to synthetic.
Then mast is as light as you can afford ho through the deck. Remove all unnecessary winches, fittings etc.
Carbon wheel is a waste of money, but carbon rudder could give you exceptional results.
Inside the boat, some weight might be saved by making composite floorboards. Also look into your headliner if it is made from plywood panels or other heavy stuff go for foam covered with vinyl or similar lightweight solution. Remove all the doors that are hinged, remove salon table. Afterwards go sailing and look which items are necessary for you and which you can live without. You will be surprised to see how many shit is not required.
