With the #while loop in place your macro returns a number of objects (800 
boxes) rather than an object, so when it hits the second object it should 
complain. You can use a union:
union { ship () translate <.1,0,0> }

or you could wrap your #while loop in a union statement within the macro, in 
which case it returns a single consolidated object which is a union of your 
800 boxes and your object statement should then work fine.
