Cape Town - The Port of Cape Town has been affected by gale force winds, forcing it to deny access to certain vessels due to safety concerns.MSC Cruises announced in a statement that the Cape Town Port authority will only allow the MSC Sinfonia, returning from a 3-night cruise from Mossel Bay, to dock at 06:00 on 11 December 2012 - if the wind conditions have eased.While the port is not closed entirely, certain vessels have been halted from sailing because it was too risky. Cruise liners are especially risky to launch because of their height, which offers a lot of wind resistance. This was combined with a narrow pathway that had to be negotiated in and out of Duncan Dock.MSC Crusies has advised passengers due to embark on the 4-night cruise to Luderitz to head to the the Southern Sun Waterfront for the night where arrangements have been made to accommodate them. The lost day has forced an itinerary change - the Luderitz trip has been cancelled and replaced with a 3 night cruise to Mossel Bay - scheduled to leave between 06:00 and 09:00 on Tuesday if the wind subsides and access to the port is allowed.Allan Foggitt, Marketing Director, Starlight Cruise said travel plans for those waiting to disembark have also be made. "All passengers booked on the next cruise who are not satisfied with the itinerary change will need to contact MSC cruises for an update on the compensations measures available to them," Foggitt said.
