The no-strand rule now asks whether the ship could leave the
destination on a full tank where fuel is sold, or on what is left
after the leg where it isn't. Emergency fuel is offered to an idle
ship that can't reach anywhere when the player can't afford the
shortfall: the cheapest leg's fuel at 2.5x the local price.
