3 nautical miles (6000 yards offshore) would be the limit of California law, at least by the definition in 43 USC 1312:US Code Title 43
I believe California claims out to the 12 mile limit but can't confirm it.
Search here for California firearms carry laws:California Code
Caution: I have two brain cells. Sometimes they both work at the same time.
