Snip good comments.

One disadvantage of the double hull used for streamlining is that there is a lot of mass 
(in this case water) within the total hull envelope that the motors have to start and 
stop.  Thsi would imply either a larger motors and props to overcome the inertia, or put 
up with sluggishness.
