As I said, The dropoff is rapid (from the crew's point of view) and 
leaves the ship going about .88(I have the numbers at home) of C.  I n 
addition, the sail would be subjected to extreme stress.  While this 
might be acceptable if you are expecting to use a lineac to finish your 
decell, it's too risky IMHO if you are expecting  are expecting to finish 
off with a sail.
