I've a cast iron keel that has been rusting quietly under my boat for
the last few years. Most of the antifouling paint on the keel is on
rusty 'scabs'.

What is the best way of removing the paint and 'scabs' from the keel?

Unquestionably shotblasting as others have said, you will get the whole boat
cleaned and primed in a day.
However if you have a few weeks /months free time and wish to spend a
similar amount of money using an angle grinder (disks at £5 each) you could
take pictures and claim an ididit diy award.
