We finally found time to try something we've wanted to do for a long time.
This project is an experiment to get a feel for how the performance of our BLENDED-WING fins is affected by the addition of a fence at the outside base of the fin. The idea behind the fence is to enhance the water flow over the lower section of the fin.
The shape of the fence is designed to push water upward from the base, which should improve the fin's effectiveness.
We are going to experiment with this fin a little differently. Instead of testing a set of fins, we will have one primary fin with the fence and another primary fin without it. That way we hope to gain some better insights into how the fence works.
People have experimented with fences similar to this before, but they have never used one on a fin like the GR8, and certainly never with the BLENDED-WING profile.
We wouldn't want to have to hand foil a lot of these fins, as it is a ton of work but rewarding in its own way.
Once we have it tested, we'll report back with the findings.
