Hartzell Propeller announced today (February 25) its new Falcon composite-propeller series. The Falcon series kicks off with the Kestrel, a light-weight, constant-speed propeller designed specifically for aircraft powered by the Rotax 916 engine. Piqua, Ohio-based Hartzell said the Kestrel has received ASTM approval and FAA certification is expected later this year. The launch application for the Kestrel is the CubCrafters Carbon Cub UL.

I doubt it would be durable for floatplane operations.

Looks like nice work by Hartzell. Now all that has to happen to make it a great combination with the Rotax 916iS is for Rotax to consistently make those engines with properly hardened crankcases and gearboxes.

Looks Like my old Whirlwind with a Hartzell sticker. Buy a company slap some stickers on their products and call it new.

Why?

Composite propellers are more delicate than aluminum props and seaplane activities are about as unforgiving for props as you can find short of sandstorms I would think. The best seaplane props are usually long two bladed aluminum props which generate a large volume of air for takeoff as opposed to a smaller cone of higher speed air generated by a multi-bladed prop.
