What should I expect the response of my >kayak to be if I moved 1" forward or 1" backward ? Unless the seat is moved at the same time the center of gravity should not alter much and, as a result the boat will not be affected much. The biggest change will be in your comfort level. To find out how much change there will be ask your boat builder how much moment is required to change the trim one inch. For an average male moving the upper torso two inches should only produce about 15 - 20 foot pounds of moment. Typical sea kayaks will need about 70 - 80 foot pounds to alter the trim one inch. My experience is that this makes little difference except when surfing.
