So am I correct in stating that the S-band radar is typically used for

Basically correct. *The National Weather Service uses S Band radar for
weather tracking out to 200 miles or so using high power and large
antennas.

I'm not sure that it is safe to assume that large ships will always be
using an X Band radar if that is what you are driving at.

What are the radar requirements for ships up to 300 tons and over 300 tons?

CFR
Subpart 32.15—Navigation Equipment
32.15–30 Radar—T/OC.

Pretty basic requirements Geoff. 1,600 ton+ must have a radar, no
specific type or back-up required.
