Hyperdrive
The Xeelee hyperdrive functions by moving the ship from one point in space to another instantaneously. Though the travel time between points is zero, there is a short pause between each jump required to compute the parameters of the next jump. This pause was a couple seconds when a Xeelee Nightfighter was flown by Jim Bolder, however it is implied that Xeelee pilots operate their craft more efficiently. This hyperdrive can cross at least 100 parsecs in a single jump if required, however the Xeelee have been known to use much smaller jumps tactically, even in combat. The hyperdrive does not rely on the craft being entirely made of Xeelee construction material, as an instance of one jumping with another ship tied to its back was shown in The Ring.
