Depends on the boat
I do not have much experience with full keel boats, which I understand will heave-to well, i.e., somewhere in the range of 45 degrees off the wind.
The fin keel boats I sail tend to heave-to on a beam reach. I takes a sone fiddling with the rudder, the main and the foresail to get the bow up in to the wind.
