Interesting. I thought the only good way to improve the directional stability was added tail area.Not only careless but illegal. The aux stabs or ventral fins are part of the float STC and are required. Cessna had a modification kit to eliminate the ventral fin; it involved a non-linear rudder return spring system that increased breakout forces enormously and improved directional stability while on floats.
Some seaplanes have used VG,s also, to improve stability.
