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.
