The Jet Boat:
My first skethup design, woohoo.
Anyway, I was looking around, and this concept was never addressed, so here it is.
I tried to make it look as "marsy as possible, hence the coloring.
How it works: most boats, as you probably know, are powered by propellers, but not this one, this one is powered by a jet engine. The basic idea behind a jet engine in an airplane is the same as the idea behind a propeller, however, it uses a compressor, allowing the air to be expelled out the back at a much faster spees than is possible with a propeller. You can clearly see the compessor in this design, however, it is quite obvious that there is no turbine. I thought about this for a long time, and decided that a turbine would not be the best way to propell a boat, so I tried a giant propeller with a compressor, but I couldn't get it to work.
This design is similar to an air jet, except instead of expelling air out the back, it does water/lava.
this design allows for maximum control, as it is both thrust vectored, and has a rudder (to come)
Please provide criticism and comments, without them, 2 things would happen, I will never get better a sketchup, and this design will never get better.
