Toroidal propeller for eFoil

Since yesterday we are testing a toroidal propeller for eFoils. It is an aluminum prototype.

Here you can see the aluminum prototype next to other eFoil propellers:

There will be a full review soon, but here are some initial impressions:

What is the conclusion after the test? Was it more efficient?

We have no hard data yet, but the prop will be modified.
