The advice to Careen is good if you can't afford to slip but it's not just the matter of cleaning off the growth, unless you antifoul the thing the growth will be back in no time flat.
If the growth is really bad then you are going to need a water jet to clean it off or you will be scrapping for eons. You might also consider the fact that if the boat has been unloved for quite some time then there may be other work required below water line. Prop shaft anode to begin with, through hulls may be so clagged up that you'll need to take them off for cleaning or even replacement, rudder stock and shaft may need work.
It's also often the case when you pull a boat out of the water that the beard under the keel is much worse than the growth you can see from above water. You will be amazed by how much crap you are hauling around and you'll be absolutely stunned by her sailing performance when she is clean and painted.
