When you are hove-to (that's the past tense of heave-to) you're probably about 40 to 60 degrees off the wind, wandering between the two--at 60 the main fills and heads you back upwind, at 40 the main luffs and the
jib is the stronger turning force, and heads you back down to 60, then repeat, repeat. Done properly, the tiller is tied down to leeward and you don't have to touch it. Takes a while to get the sail and tiller position right, but once you do, it's self-steering really. Whether it works well for you in a strong breeze you'll have to find out by experience. Try it in the lighter stuff first.
