well.. my 2p.. weight has no bearing on a "space" ship surely? Being 0 gravity an all. I suppose it won't be able to get as close to a star or land on a planet as a smaller ship can (lighter)...
I'd say make it out of Tungsten the hardest metal known to man. But then again we are talking future space, so maybe aluminium fused with some random stuff is OP.
Sindroms. I love you. Not in a weird way, but your video has gotten me into Disco and I am loving every second.
Oh and I want a shark ship with a lazer cannon attached to it's head. Pretty please...
