Could this be the future and solve all our problems? (World peace is near)

 
Yeah, without price comparison it's just interesting.
 
Can it be tuned up after a hit to the prop?
 
I wondered how it compared to a Bravo 3?

And I had assumed that plane speed was more a function of the hull design than the prop.

I’ve always understood it to be more a function of slip, especially in heavy cruisers. Slip must be considerably less on these props versus their traditional counterparts since they tested very similar pitch

Pretty amazing results.

It was glossed over a bit, but it seems like a significant contribution to prop inefficiency is the vortexes generated off the tips of the blades. Vortexes cause lots of drag. The new prop’s blades don’t have tips and therefore don’t generate drag-inducing vortexes.
 
I'd love to visit the manufacturing facility and see how they are made, especially the ones big enough to push a ship. I also wonder how they will price out.
 
You can fill out a sales inquiry on their website and order direct from factory....no mention of price.

The "recreational" category is listed as "coming soon". Since they have inboards listed as available, I'd guess recreational includes stern drives and outboards.
 
I'm also curious. I sent them a message asking if they make props in a 30" diameter and what the cost would be. No answer yet.
