And you can move the floats further in front you are then getting your step in position at or near the CG. If the tips were at the prop you could move them 3 inches forward and voila!

The plane will dip less at the front and the prop will pick up less or no water, when taxiing, also.

You should have mounts on the floats that allow for fore and aft mount flexibility. You move the float attach points allong the float to change the setup.

Just my .02.
