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:

Very interesting - thank you for the test! I am looking forward to the result in some days.

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

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