WTF? Can't they put a muffler system on them, or is it the blades that
make the most noise?

Trust me. *The engine is loud.

The prop is much, much, louder.

Down at Wootens the make the passengers and the drivers wear ear
protection. I don't know of anyone who doesn't.
I do know a couple guys down in Everglades City who have airboats.

So, why not put a shroud round the prop, it shoudl at least silence it
some?- Hide quoted text -

The hovercraft I built had an optional build for a close fitting
shroud that actually was supposed to boost thrust a little. I made it
and installed it. As I recall it didn't help noise much if any at all.
