Why would I test with parts blocked or locked? Then it would simply be an old fashioned fin. In all the testing that has never happened.Did you test your fin design with some of the moving parts blocked and how did they fare?
How easy do you think washing off dirt and salt will be from those tough to reach places?
Isn't the point to go the same speed you usually do, but using less gas?Most of us don't go diving to just swim fast underwater ...
a solution looking for a problem ?

What tough to reach places? I have never had any issues with rinsing the fins. Also the final version will be much sleeker and more streamlined.
Absolutely. And that is exactly what is going on. The spinoff is the ablility to go faster since it is using less energy. I am not advocating swimming fast. It is just nice to have the insurance in those rare cases where it is needed.Isn't the point to go the same speed you usually do, but using less gas?
So far there has never been a failure in the hinges. They will be made of the same material that has been in fins for decades. The prototypes are using a material which is much weaker than the final production version so the final result will be even stronger.Since every hinge is a point of potential failure, every time I look at your fins all I see is multiple points of potential failure. Not a reliable long term piece of potential equipment.
The point is they are designed to take plenty of abuse.
This is a good point. Is there greater potential for entanglement with the vanes. Also, if the kelp (or other entangling material) gets caught up in the vanes, can they be torn out as the diver is working to get untangled?Send a pair and let's see if they survive a kelp crawl in Monterey.

No doubt if you took a knife to it you could cut it but you can do that to today's fins too. If you put the MaxAir and a Rocket fin in a shredder they will both get shredded and I suppose the MaxAir will get shredded a bit faster. The point is they are designed to take plenty of abuse.
