Vertical (up/down) acceleration is a measure on how hard a boat rides in waves. The phenomenon is called “pounding” or “slamming”. The acceleration is usually measured in terms of G’s, this is why it is also referred to as G-force. Because waves are not alike on any two occasions, it is very difficult to say that a boat has exactly X G’s in sea state Y. Measurements of vertical acceleration are therefore usually relative and comparative.
