My Design

 

     The design I have chosen is a culmination of many changes and modifications I have made since I first began working on this project.  A number of factors have driven the evolution of my design.  

 1)  The necessity to launch the sub from a trailer and to be able to tow behind a vehicle. 

 2)  Speed

 3)  The ability to build a successful sub at reasonable price.

 4)  The common problem that all small submersibles have, which is the amount of freeboard between the open hatch and the waterline.

 

  The inspiration for part of my design came from the submersible "Deep Flight Aviator" .   The submarine designer needs to make certain design criteria before anything can be done simply because the size of the submarine can become so enormous that once you're done building it you may not be able to get it to the water.

  One aspect to my design which is rather unique can be traced back to a ship that must have made a big impression on me when I was a kid.   The ship was "Flip" Floating Instrument Platform, operated by Scripps Institute of Oceanography.  Flip is a one of a kind vessel that is able to change it's orientation from a horizontal position to a vertical position by flooding ballast tanks.  Flip is so stable in the water that it has withstood 100 mph winds and 40' seas while deployed for ocean observations.

   Since there exist the very real problem of swamping your sub in heavy seas, or even moderate seas,  the idea that I could gain extra freeboard by reorienting the sub made a lot of sense.  With this added feature though a second hatch is necessary at the back end of the sub.
