I have a steel boat (28 years) not aluminium one but the paint systems are similar if you are going back to bare metal.
The antifouling paint flaking off in the photos looks to me like the last coat of primer was left too long before over coating so no chemical key was possible. In this case the primer should have been lightly sanded to provide a mechanical key before the antifouling was applied. I have had this issue on decks and topsides
I always remove the anodes. I am going through sand blasting at the moment and the only anode I left on (the shaft one) was very well painted by the yard as well as the anode studs. Not Impressed but retrievable
