Wet rail - depends what you want to do
The truth is that dipping the rail slows us down, but its sometimes a lot of fun. Our children like to sit on the lee rail of our H23 and dangle their legs in the water. Sometimes, if we are not in a hurry, its fun to surprise them by heeling the boat so that the rail, and their bottoms, get a good dunking. Which causes them to beg for more! My wife also loves sailing on her ear.
