The plan was to key the bottom of the bottom and get any flakey patches off.
Then apply the antifoul as you would normally.
I was wondering if it would be best to just antifoul the part of the hull that would be getting submerged or to make it look tidier would it be okay to paint the whole bottom off the hull up to the edge of the tubes and the back of the transom. To give the bottom of the hull one colour rather than having half anti foul and half original hull colour.
what do you think?
I would antifoul the bit that's underwater when the boat's at rest, and add a couple of inches to allow for the splash zone. Leave the rest, which I suspect is only a bit of the bow area, as I don't think antifouling paint does well out of the water. It's certainly not glossy like the gel coat. If your Humber's like mine, you'll need to antifoul the after end of the tubes as well. My tubes are navy blue and you can't see the navy antifouling, it's exactly the same colour.
Of course, only do this if you keep the boat afloat during the season, otherwise as others have suggested, get it off.
