Shad your probably correct its only when you get into a real force ten that this glitch happenes when the height of the wave and its trough is higher/lower than the boat.....From what I have observed all the submarines have a "Touch" of bouyancy, they will move up and down as if in a swell but its very minimal....When your boat is in a big storm it becomes apparent that this up/down is just not enough to compensate for the high/low point of the BIG waves. Thus you start to ride on "Air".....
Deep six
