  Ship gets lighter as more fuel is destroyed. Ship gets heavier as it gets closer to light speed.

  At 90% of light speed, the ship’s mass would be around 2.3x its rest mass.

    the mass increase due to relativistic effects is really really small, significantly smaller than the weight loss due to fuel consumption, which btw is described by the Rocket Equation.
