We don't have to worry about frozen spray like you do but we still use
the antifreeze just to be on the safe side.

I just did some research on this. Sea water density increases as it get
colder until the temperature hits 4 degrees celsius then expands until
it freezes. So don't take a loaded boat too far north.

Winter displacement will be more affected by frozen spray than any variation
due to temperature. Not to mention the required antifreeze for the crew.
