How many days does it take to travel to Jamaica from England by ship?

From Montego Bay to Southampton UK will take at least 9 days with most transatlantic repositioning cruises taking longer due to stops in Barbados and the Azores. Merchant ships will do the direct run to Kingston in 10 days if your lucky enough to find one. When I was a child there were many passenger runs from England to Jamaica but now there are very few, Last year there was only one and that was on Ocean Village cruises (and it took 14 days)
