For example, when meeting a steep head sea, many boats run more comfortably and efficiently with the bow down slightly, allowing the sharper forward-V to knife through the waves. Conversely, in a following sea and when overtaking waves, it is often safer to run with the bow up a bit to help prevent stuffing into the backside of a roller.
There are three ways to adjust the running attitude of a boat:**
This is the most rudimentary method, and practical only on smaller boats. On big boats, moving loose gear and equipment forward or aft usually doesn't make much of a difference.
