Same drives work about as well for a small fast ship, or a big slow ship.

I was figuring up to 40% c for Fuel sail.

If you can get a multigeneratin ship out at any non-laughable speed - you can 
get a small short duratin ship up to far faster speeds.

For what purpose?  The risk goes up tremendosly, but adds little benifit.
