>having the sword air-delivered with rocket at the last minute
the only non-stupid-jap-sentai-ranger version of that I've ever seen is Iron Man's Hulkbuster suite in Ultron, which was both cool and made sense
>Your "cargo ship" is more of a barge to me
it's thin but should still mass at least a thousand tons
>frigate go as low as 2,000 tons around its size, plus hiding volume underwater
ships, even warships, are very buoyant with lots of air inside so they are actually surprisingly light for their volume
even a submarine - the most cramped ship - has basically the density of water, for obvious reasons. a surface ship is much much more buoyant for its size.
>machinery rather than mostly water
>boat don't let water in
no, treat a Jaeger as a scaled-up human, made of metal rather than flesh
we are 60% water, a Jaeger isn't. scale up a 2 metre tall human to 80 metres, and s/he would weigh about 7,000 tons. now replace the water with steel and machinery? steel is over 7x the density of water. if you replace 3,500 tons of the water in that 7,000-ton humanoid with steel, you get 28,000 tons
even if you argue that not all the water in a human body is turned into steel machinery in a Jaeger - after all, there must be plastics, gas tanks, chemicals and lubricants, and plenty of air for maintenance crawlspaces - it would still be much heavier than 7,000 tons. if it was 7,000 tons, theoretically a Jaeger can swim, just as humans can...
