When i was new to sailing, not that long ago, I had no idea how to deal with the increased weather helm
as the wind and heel increased. Once I had full rudder away from weather
and could not turn down wind to head
home. Since the heel was pretty extreme and letting it turn up wind would have meant momentarily heeling even further I kept my foot on the wheel and slowly eased the main, which eased the weather helm
allowing me steerage to leeward. I no longer sail with heavy weather helm, Adjustments to the main can fine tune the feel of the helm very quickly. Obviously having the right amount of sail for the conditions is the first step, but when lazy and the wind picks up, I can just let the main out enough to to dump some the wind and right the boat but keep up a good clip until reefing is a must.
