Hadn't thought of that wind_magic but channel 22A in the US is a heavily used Coast Guard channel, so I'd think the FCC would be less than amused at the 'rebroadcast", and the anchorage/marina frequency police would be all over that too.
The author didn't say whether the interference was constant or intermittent. Outside the US, the rules, if there are any, are far less enforced.
