Frequently Asked Questions

What do you mean when you say pressure hull/cabin? The term "pressure hull" is an industry term that actually means the opposite of what it implies.  A pressure hull is a cabin that protects the crew from changes in pressure.  In other words, it is better described as a pressure boundary cabin wherein, once you close the hatch, the atmospheric pressure captured at that time is maintained regardless of the changes in depth.

What are we seeing pictures of?  You are seeing pictures of our proof of concept R&D vessel.  It was built to prove the effectiveness of the concept (speedboat/submarine hybrid) is not certified, meaning it was not built to DNV-GL or ABS standards. Its main purpose was simply to prove that a speedboat and submarine hybrid could in fact work as we had advertised. To keep costs down this platform was built using steel and was not equipped with a long life cycle or certification in mind.  

How does something shaped like that withstand the pressure at depth?  The only items that withstands pressure at depth is the cylindrical cabin and battery tubes.  The surface hull is completely flooded during a dive and therefore experiences no pressure differential.   

How deep has the Hyper-Sub gone? We installed a cabin rated for 100 feet so we kept our depth below 40 feet. The cabin seen in our photos incorporated variable geometry for its promotional value. If we had installed a cabin rated for 2,000 feet, which is available, we could have taken her to 500 feet. The only limitation to depth is the cabin you install.  

Why so many flat surfaces?  There is a lot of drag there.  Yes, we intentionally incorporated many flat surfaces for promotional reasons.  This would not be the case with industrial or government versions.  

You say that the Hyper-Sub historic. Why do you say that? The Hyper-Sub MSV, even our limited concept version, has shown that the solutions required in order for a speedboat and submarine hybrid to function properly have been resolved.  From an engineering stand point, it was supposed to be impossible for a vessel to have the power to weight ratio required to be a speedboat while also being capable of  diving as a submarine.  It is this solution that grants a new level of independence and economy for sub-sea access.  Beyond this, our concept vessel proved, whether empirically or demonstrably, what is now possible through the incorporation of standard engineering and manufacturing practices.  For example, because of our cabin selection, we limited our dives to 30 feet but any engineer who is familiar with the Hyper-Sub's design will tell you that it is capable of diving to 1,000 feet simply through the incorporation of a standard certified cabin.   

Is there more than one Hyper-Sub?  I notice it looks different depending on the photo I am seeing.  No, there is only one Hyper-Sub.  Over the course of testing we changed the bow.  There are actually three bow configurations.  Originally, the Company did not intend to prove anything beyond the crafts ability to transit from surface mode to subsurface mode and to function properly. However, over time, as we acquired additional skills and funding, we realized that we might also have an opportunity to demonstrate the Hyper-Sub's surface speed capabilities.  Hence the changes in the bow design.  Though testing was suspended prior to focusing on the crafts high speed capabilities, its surface speed will be demonstrated during the next phase of testing.
