The dive site Offshore Barges is an offshore recent wreck in the Simon's Town area of False Bay, near Cape Town in the Western Cape province of South Africa.
This is one of the closest 40 m wreck dives to a convenient launch site in False Bay See also: Diving the Cape Peninsula and False Bay#Understand
North Barge 📍: S34°12.473' E18°30.950'.
South Barge 📍: S34°12.483' E18°30.936'.
This site is in the Table Mountain National Park Marine Protected Area, proclaimed in 2004. A permit is required.
The name "Offshore Barges" is a description of the main features of the site.
Maximum depth is about 40 m, and the top of the wreckage is about 38 m.
Visibility is variable and unpredictable. This is a site where visibility can be very poor in a band a few metres above the bottom, while quite a bit better above 30 m. The reason for this is not known.
The rather wasted wreckage of two rectangular steel barges on a flat sand bottom.
Geology: Sand bottom with shell.
The site will usually be at it's best in early winter, but there are also occasional opportunities at other times
This is an area which sometimes has a dark band of murky water below 30 m, caused by unknown circumstances, possibly seasonal, resulting in poor visibility.

Cold water is possible. Strong winds may develop over a short time. Nitrogen narcosis may be expected on air and Nitrox dives. If there is a current there is a risk of being carried away from the wreck if you do not descend and ascend on the shotline or anchor cable.
Competence and certification to dive to 40 m is expected. The ability to deploy a DSMB is strongly recommended. Training and competence in the use of other equipment that may be used is necessary. The charter skippers will generally only take divers that they know are capable or are under direct supervision of an instructor.

A DSMB and reel are highly recommended in case of being separated and off the wreck. There is seldom much current, so an upline is not required. A light is also strongly recommended as it is frequently quite dark due to overcast conditions and poor visibility above the thermocline.
Nitrox can increase no-stop time, and Trimix will reduce the severity of nitrogen narcosis. A dry suit will be warmer both during the dive and while travelling there and back, specially in winter. A fairly large cylinder will be required, and either a pony cylinder or isolation manifolded twins will give the peace of mind of an independent backup gas supply.
