A while ago, I blogged about the Lunocet – a monofin fused with cycling shoes with a biometric design to increase efficiency of movement in underwater dolphin kick for SCUBA divers and snorkelers.

According to the manufacturer’s website, the fin helped swimmers reach speeds of 8 miles/hour underwater! A short term goal of the developers is to reach ‘true breach’ allowing a diver to dolphin-jump all the way out of the water. To do this, a swimmer would need to break the lofty 10 mph threshold.

I recently checked-up on the Lunocet to see if there were new developments since I last visited the site. I found several versions of the monofin, all with the flexibility and secure mounting of cycling shoes. I also found the following video of Lunocet testing:

This diver doesn’t use a traditional tight streamline, but has his hands apart in front of him. I wonder what kind of serious speeds a world class competitive swimmer could reach in a speedsuit and Lunocet fin! More importantly, if they wore a full body Jaked with this fin, would they be able to blend in with a pod of dolphins?
