Catamaran aqualab concept

Something I did during a section of my advanced structural drawing class towards the beginning of the semester, when our teacher told us we could draw whatever we wanted.

It's a concept for an oceanic lab that can lower its middle portion into the water, acting as a submarine. It can later be reeled up, secured, and can then be transported away above the water more quickly than it would below it.

This is by no means a very refined concept, but I put it up here just to give a sense of what I'm also interested in doing.
