Would this work?

No.

Airboats with just the fan go 70 mph, even over wet grass. I haven't seen
any sails on any of them to increase speed.

Let's think....If we put an airboat engine/fan on the bow blowing through
all that wind resistance of rigging and sails and tackle and measure the
speed.....then, clean the deck of all sailing paraphenalia and let the
airboat fan power the boat with no sailing equipment, its drag, its weight,
its moment pulling the boat over...

Which do YOU think would be faster?

I'm picking Door Number Two!
