Hello Rupert,

The Gazelle is built on a 300 ton hull with a J5 drive and my recreation, with the exception of cost, seems to match the details in CT Supplement 7.

The J4 drive is designed to move a 300 ton hull + 100 tons of fuel in drop tanks four parsecs. My apologies for not being clear at the start.
