Kevan,
Those swimming area buoys are put in place by each individual property to mark their own swimming zones. They are not permanently anchored and can be pulled in during rough weather. They are not always put back in the exact same location, so that would account for how they can "change" over time. The excuse you were given was "super false".
The buoys are simply markers, they have no legislative value. Jet skis routinely would ride inside the buoys because there was no real law preventing them from doing so. Operators were asked to observe the buoys, and the Marine Police could warn the operators, but that was the extent of their legal powers.
The new, regulated jet ski zones would be much farther out by a factor of 5 or more depending on the current position of an individual property's buoys. The ban will not be lifted until all these factors, including easy enforcement are put in place.
As I have mentioned, the government is taking this very seriously. To quote the JIS (Jamaican Information Service):
"The Minister added that the Task Force will provide information on the requirements for licensing of all persons operating currently.
The Jamaica Constabulary Force, Jamaica Customs, Jamaica Defence Force, Tourist Board, Maritime Authority of Jamaica, Ministry of Tourism and Entertainment, National Environment and Planning Agency, Port Authority of Jamaica and the Tourism Product Development Company (TPDCo) are members of the Task Force."
There are 9 government agencies working on all aspects of these new regulations. The ban will not be lifted until all parties agree on the new guidelines and how they will be regulated, from importation and duty. licensing and taxation, safety of riders and swimmers, police and enforcement as well as the environmental impact. The will to enforce will have the powers of 9 government agencies behind it.
